Massive Terraria CRT

Irrelevant Part Just to Remove an Inaccurate Calc
So first thing's first, we have the Celestial Towers at Brown Dwarf level for moving moons very fast. But as you can see, even in the comments of the calc, those aren't moons, they are planets. The Wiki says this, and this comes from an official developer changelog.

I don't know if the image loaded, so the source site is here. It's the bottom text. With the time frame the moon calc gives, even with the closest planet, the speed is FTL. The feat would be nerfed to wherever the GBE of the planet is. Puts stuff that scales to this to Planet who aren't Celestial Towers, Endgame Terrarian and Moon Lord, for the reasons you'll see below.

Now for the juicy stuff.
Galaxy Statement and Supporting Evidence
The tooltip for the Nebula Fragment states that it contains the power of a whole galaxy, pretty straightforward. These are used to craft armor and weapons. Should scale to end-game Terrarian, Celestial Towers, and Moon Lord. Now how is this not just some random one-off statement and actually impressive? Well first, the Celestial Towers pulling the planets close is easily a very casual feat, since it's done as a byproduct by their presence, and they still have the power to have a whole army to fight the Terrarian before being defeated.

Second has to do with Terraria's official lore. In the lore, Cthulhu (just Moon Lord but before he fled) was able to threaten the fabric of Terraria, before all the Dyrads' combined power and their ambiguous magical empowerment from the planet allowed them to severely weaken him into fleeing to the other side of the Moon.

"Hey hey, wait. But doesn't it say Cthulhu was trying to destroy all life on the planet specifically?"

Yes, in the paragraph before. However, the lore uses the word "Terraria" to refer to the universe as well. The statement "fabric of Terraria" makes very little sense if said in the context of the planet. It is far more likely referring to the universe of Terraria ("Fabric of the Earth" compared to the "fabric of the universe/reality"). Additionally, the lore images are in the perspective of an observing historian, and so they use the word "seemingly" when talking about Moon Lord's plan, and given they live on the planet that is being endangered, it makes sense for them to assume their planet is the one being targeted.

"If it was written by someone who isn't a godly being, how do they know about the creation of the universe?"

The events of Moon Lord are still a current event at the time it was written. The creation of the universe and other various things such as the Corruption and Crimson are things that are likely to have been figured out hundreds of years ago through experimentation and whatever magical ways they found that out. That, and they explain the creation of the world earnestly with zero doubt, unlike talking about the Moon Lord, who they write with unsure-ness. It would also be impossible for them to find the true motive or plans of Moon Lord, given they fled to "this day".

Of course, Terrarian wouldn't scale to a full-power Moon Lord. This is because Moon Lord was weakened when retreating to the Moon, and is said to be regaining his power presumably, which is told further when they explain that the Mechanic's Mechanical Bosses were all meant to fuse with Moon Lord to gain his power to full again. Even in-game, we see Moon Lord having no lower body, meaning they are clearly weakened, and the Terrarian just beats them in smaller chunks.

"Bruh, so why you saying all of this"

Why is any of this relevant? This is just to show that massively powerful beings such as Moon Lord (debatably Uni+ for threatening the fabric of the universe, but doesn't matter, point is that they're insanely powerful and above Planet level) do, and have existed in Terraria, and thus the statement about the Nebula Fragments holding the power of a galaxy within them isn't an outlier written on a whim, and does actually fall in line with levels of power in the series. Additionally, it's something that is on every piece of Nebula Fragment you get, and every Fragment type has a different statement about the nature of them (note that the "fury" of the universe isn't really something quantifiable since we have no clue what this suggests, so no Universal Terraria, but Galaxy is very blatant).

Edit: Moon Lord at the end of the game has two eyes, a skull, a spine and a brain, meaning his body healed back to full power, and thus those scaling to him should be Universe level+ as well.


Agree for Galaxy (actually just Large Planet) + Universe level: 13 (ObberGobb, Zurawi, Dalesean027, Greatsage13th, Lou_change, BestMGQScalerEver, Napoleondevious, Deidalius, Pyro9278, Super_Ascended_Sean_Pazdera, Saqphire, AyOgUyS, Abscoolguy)
Agree for only Galaxy: 1 (YmTheSuper)
Disagree:
Neutral:

 

[YmTheSuper]

I agree with the celestial pillars' feat having nothing to do with the moon. The celestial objects in the background are clearly planets and are never mentioned to be moons (even the picture of the achievements clearly showcases them as planets)

Disagree with the Moon Lord/Cthulhu scaling to universal or using it as supporting evidence for galaxy scaling.
1. The statement of "the very fabric of Terraria itself seemed on the precipice of doom" is extremely vague and it can't be really used to scale him to a certain level or AP as the description is unclear (the fabric of Terraria could refer to the universe, space-time, life or it could be hyperbolic for all we know, point is this isn't really a clear statement)

Yes, in the paragraph before. However, the lore uses the word "Terraria" to refer to the universe as well. The statement "fabric of Terraria" makes very little sense if said in the context of the planet. It is far more likely referring to the universe of Terraria ("Fabric of the Earth" compared to the "fabric of the universe/reality"). Additionally, the lore images are in the perspective of an observing historian, and so they use the word "seemingly" when talking about Moon Lord's plan, and given they live on the planet that is being endangered, it makes sense for them to assume their planet is the one being targeted.

Why would the historians know that the universe as a whole was in danger while thinking that only their planet is targeted?

The lore itself states here that Cthulhu arrived to your world to rain destruction on it and have dominion over all of its sentient life and the fabric of terraria became in danger only after he arrived to your world and attempted to take over it leads me to believe that this is only referring to the world not the universe considering they aren't the same and the unsureness of the narrator of the lore makes it more likely that the fabric of Terraria seeming in the precipice of doom doesn't actually to the universe in danger of being destroyed. This is further supported by the statement "The Dryads, with their unparalleled connection to the planet, were Terraria's truly last hope as they joined together to save all life from annihilation." making it apparent that the planet was the thing that was threatened.

In conclusion due the vagueness of the statement (not really scaling to any AP) and other interpretations of it being more likely i think we can't really use it as an argument for uni+ or even as a supporting argument for galaxy level.

As for the nebula fragments I am unsure about using the item tooltip for an upgrade this big but it definitely is a better argument than the Cthulhu lore and I'm neutral on it in particular for now.

 

[ObberGobb]

Personally, I don't think the Celestial Pillars scaling makes sense anyway. Why does the pillars making planets appear in the sky have anything to do with the attack potency of the Lunatic Cultist?

I agree with the Galaxy level scaling, and even though its a tooltip its fairly explicit and I think is much stronger than any of the current Hardmode scaling we have. Universe level seems good too.

 

[Dalesean027]

The statement of "the very fabric of Terraria itself seemed on the precipice of doom" is extremely vague and it can't be really used to scale him to a certain level or AP as the description is unclear (the fabric of Terraria could refer to the universe, space-time, life or it could be hyperbolic for all we know, point is this isn't really a clear statement)

As far as low 2-C goes the universe and spacetime would be the same thing in this case because all low 2-C really requires is significantly affected a universe sized body with some kind of effect which if the universe is terraria then saying the very fabric of the universe is in danger that's pretty explicit.

Why would the historians know that the universe as a whole was in danger while thinking that only their planet is targeted?

This isn't an argument and there's nothing to suggest they don't know the scale of it, in fact its just outright blatanlt what we're told that the universe is terraria alongside the other statement of the "frabric of terraria" so I'm not seeing how you're getting anything differnt when its very clearly analogous with "the universe" in context.

The lore itself states here that Cthulhu arrived to your world to rain destruction on it and have dominion over all of its sentient life and the fabric of terraria became in danger

Nothing here really suggest the planet only when this for one is the completed cthulhu so the lore is our only gauge and they outright give it the same statements that its power is "immeasurable" and that its a threat to the "fabric of terraria" more that would suggest the universe itself.

only referring to the world not the universe considering they aren't the same

Nothing here says that aren't the same and if anything it supports it (side not if you take a series at times refereing to its universe the world sometimes as somehow to mean the planet only then ya gotta expand yourself because this happens quite commonly) anyways in this scan they refer to the universe as the "world of terraria" and the "terraria universe" quite blatanly and even talk about other planets in the universe saying "Each world of terraria" which further suggest you're dealing with a structure larger than the size of mulitple planets at worst

Overall your scans if anything support the statements in the OP, if anything having the nubulae fragments say they contain the power of a whole galaxy is even further support for so I'm fine with low 2-C

Common sense kinda kicks in too cause like no one says "the fabric of the planet" is in danger

 

[FriendOfTheTeaParty]

I heard this from DMUA but the "power of a galaxy" taken literally is just 5-A. but you can probably multiply whatever exact value it is by 60x since the most fragments the pillar can drop is 60

There's also solar fragment having fury of the universe but it's a bit more vague than power of a galaxy.

I think universal stuff is fine tbh and stuff IS intended to be on a cosmic level.

 

[YmTheSuper]

This isn't an argument and there's nothing to suggest they don't know the scale of it, in fact its just outright blatanlt what we're told that the universe is terraria alongside the other statement of the "frabric of terraria" so I'm not seeing how you're getting anything differnt when its very clearly analogous with "the universe" in context.

I was just responding to OP where he stated that the historians only thought their planet was targeted and in danger.

Nothing here really suggest the planet only when this for one is the completed cthulhu so the lore is our only gauge and they outright give it the same statements that its power is "immeasurable" and that its a threat to the "fabric of terraria" more that would suggest the universe itself.

"In the blind spot of the universe, there exists a planet of unprecedented potential: your world!"
And immeasurable is just a word that's used hyperbolically in fiction, it's meaningless without context. Considering the danger of destruction only started when Cthulhu arrived to your world (planet) and that his sole goal being raining destruction and having dominion over the sentient life in "Your World", him not affecting the universe but rather only the players' world isn't a baseless assumption. (also the fabric of terraria could be referring to space-time on a local level which is not absurd considering the summoning of the Moon Lord in-game causes the screen to distort or it could be a hyperbolic statement to showcase his overwhelming power)

Nothing here says that aren't the same and if anything it supports it

"Countless living worlds were created a now exist within the Terraria Universe" with one of them being "Your World" since "In the blind spot of the universe, there exists a planet of unprecedented potential: your world!".

Common sense kinda kicks in too cause like no one says "the fabric of the planet" is in danger

Fair enough but the usage and meaning of the fabric of reality varies a lot across fiction.

Another thing is that assuming the fabric of terraria refers to the universe itself, the usage of seemed in "The very fabric of Terraria itself seemed on the precipice of doom" implies uncertainty and I'm not sure if we can really scale Cthulhu to Low 2-C because it seemed that the universe is almost doomed. It's very vague.

I understand where you're coming from and while yes the statement can be used for scaling to low 2-C i just don't think it's clear enough to get an upgrade this large to the verse (although this would only apply to Cthulhu so It doesn't really matter for the rest of the verse.)

As for the Nebula Fragment, after thinking I agree with it having the power of a galaxy, the statement is pretty clear cut and there isn't really any way to portray it in game other than tooltip info and the devs clearly have the intention of the verse being cosmic in scale and the usage of such tooltips in games in general should looked at in a case by case basis which I think here is fine (although I imagine the scaling would be to the energy produced by a galaxy and not to the energy needed to destroy it)

 

[Zurawi]

Moon Lord is described as being without limits to his powers (Bestiary entry and official lore pages), wouldn't that be High 3-A at the very least?

 

[YmTheSuper]

That would be NLF

 

[Dalesean027]

"In the blind spot of the universe, there exists a planet of unprecedented potential: your world!"

Yup this still ≠ Terraria itself being just the planet

As they still say "Each world of Terraria" so your world would just one of said worlds in Terraria, again it just is clearly implicating that terraria itself would be a structure higher than just a planet so when the say the "Terraria universe" that's just pretty concretely imo at least what they're going for with that

And immeasurable is just a word that's used hyperbolically in fiction, it's meaningless without context. Considering the danger of destruction only started when Cthulhu arrived to your world (planet) and that his sole goal being raining destruction and having dominion over the sentient life in "Your World", him not affecting the universe but rather only the players' world isn't a baseless assumption

This is valid they do actually say "your world" specifically and "the world" (in the context of the planet not the world of terraria as a whole which would be the universe) for that Cthulhu portion so that is at least a threat to just the planet for that part ai I'll concede there

the fabric of terraria could be referring to space-time on a local level which is not absurd considering the summoning of the Moon Lord in-game causes the screen to distort or it could be a hyperbolic statement to showcase his overwhelming power)

This is a no though for me, they do refer to Terraria as the universe as a whole and very much when they mention "Terraria" say it in a way where it is a structure larger than just a planet or even multiple, they literally do say the terraria universe so that local affect thing I don't agree with when they do at least make a clear distinction of when something is just affecting the world as in the planet or terraria as in the universe.

Gameplay limitations aren't an argument against since they have to depict it some way.

"Countless living worlds were created a now exist within the Terraria Universe" with one of them being "Your World" since "In the blind spot of the universe, there exists a planet of unprecedented potential: your world!".

This was moreso not for the one that explicitly did say one world but for how they refer to terraria itself, again i.e "Terraria Universe", The "World of Terraria" or statments implying higher size "Each world of Terraria". This is just all to say again when they reference terraria as a whole they mean the universe

Another thing is that assuming the fabric of terraria refers to the universe itself, the usage of seemed in "The very fabric of Terraria itself seemed on the precipice of doom" implies uncertainty and I'm not sure if we can really scale Cthulhu to Low 2-C because it seemed that the universe is almost doomed. It's very vague.

Yeah can drop it for the full power original Cthulu but moon lord should be good regardless as I said given the additional context the frabric of terraria should be in reference to the universe itself which does fit our sites current criteria for low 2-C as all thats required is significantly affecting the universe in some way that would cause its destruction, even if its not destroyed or anything in screen the statement should still qualify

 

[Zurawi]

That would be NLF

Fair enought

I think I agree
Terraria's 2-C now
wild

 

[Topaz404]

Hol' on now, you need staff votes to actually see if it applies to profiles-

 

[MaybeWantsToEdit]

Just to clarify, since I hear about the literal energy output of a galaxy irl being used, what tier would straight up an entire galaxy's energy output be. There's the light, but also the motion of all the stars and planets within it. (I'm not sure if this is the way to go though because the tooltip is vague on exactly what "energy" of a galaxy it's from. So pretty sure it's just meant to be baseline Galaxy)

 

[Napoleondevious]

i agree with galaxy tooltip

That would be NLF

how is that nlf when hes stated to have no limits to his power ? i disagree with this statement anyway

You should probably seperate the votes between those who agree with low 2-C, those agree with the galaxy scaling and those who just disagree.

Personally you can put me for agree low 2-C however, funnily enough though the average galaxy has 100 million stars so so like 100 million * 3.83e26 W (suns per second output) = 9.154 Yottatons (5-A), but the milky way has 100 billion stars so like that'd be 3.83e+37 Joules or 5-A+

 

[MaybeWantsToEdit]

Personally you can put me for agree low 2-C

Do you also vote for agreeing with galaxy tooltip?

 

[Dalesean027]

Do you also vote for agreeing with galaxy tooltip?

I said its fine as support but I'd say the low 2-C is what I mainly agree on

 

[YmTheSuper]

Yeah can drop it for the full power original Cthulu but moon lord should be good regardless

This is confusing me since the feat would only be used to scale Cthulhu in the first place who himself is full power Moon Lord before he became weaker.

 

[Dalesean027]

I thought we didn't have outright confirmation of this? If we did get confirnation then the moonlord should still scale to low 2-C then regardless

 

[Dalesean027]

Well regardless its implied at least I suppose

 

[YmTheSuper]

I thought we didn't have outright confirmation of this? If we did get confirnation then the moonlord should still scale to low 2-C then regardless

Well it is stated that Cthulhu had his eyes, parts of his skeleton and parts of his brain removed which lead him to retreat to the dark side of the moon to regain his power and that the cultists are trying to bring him back (and in-game they are attempting to bring back the moon lord which lines up perfectly)

Also the eyes that spawn out of the Moon Lord during his boss fight are called True Eyes of Cthulhu and his bestiary entry states "freed from his lunar prison" further supporting him and Cthulhu being the same.

Yup thats fine then been a while since I played but yeah being that they're one and the same the statement of him threatening the frabric of the universes and that he'd destroy the world of terraria should still hold up both things can exist as the isn't mutually exclusive , he can be a threat the planet and universe as he has statements for both

 

[Zurawi]

I believe that even developers said Moon Lord and Cthulhu are the same being and the statement that ML was Cthulhu's brother was a joke

 

[OrangeFR]

For the "Contains the power of a galaxy" statement, shouldn't we take into account the fact that almost all galaxies contain a supermassive black hole in the center? That might put it a bit higher.

 

[OrangeFR]

So I decided to look at all of the tooltips (Link to the tooltips page on the wiki) in the game, and I saw 3 that might actually get something, the Solar Fragment's says that "The fury of the universe lies within this fragment" (IDK if this is 3-A or actually lower cuz it would only scale to the energy produced per second or something). Similarly, the Solar Eruption's tooltip says that with it you can "Strike with the fury of the sun" (Probably scale to the energy produced by the sun or some shi). Lastly for a lifting strength feat, the Lunar Hook's tooltip reads as this: "You want the moon? Just grapple it and pull it down!" (Probably Class P).

 

[Dalesean027]

For the "Contains the power of a galaxy" statement, shouldn't we take into account the fact that almost all galaxies contain a supermassive black hole in the center? That might put it a bit higher.

Maybe but I'm not sure, we'd need a second CGM opinion there

Strike with the fury of the sun" (Probably scale to the energy produced by the sun or some shi).

That's high 6-A

the Lunar Hook's tooltip reads as this: "You want the moon? Just grapple it and pull it down!" (Probably Class P).

No discernable timeframe but no that'd be way higher than class P

 

[MaybeWantsToEdit]

The "fury of the universe" is too vague to site as Uni. Zero clue what it's referring to, celestial objects in Terraria are inexplicably sentient so could be referring to that, etc. Also would contradict with the fact that the Terrarian fights against a Uni+ character being split amongst uneven levels of power. And given the Celestial Pillars are all roughly the same in power I think they all are generally Galaxy off of the blatant galaxy statement. The fact that it says fury instead of power implies this too

 

[OrangeFR]

Maybe but I'm not sure, we'd need a second CGM opinion there


That's high 6-A

No discernable timeframe but no that'd be way higher than class P

It might be safest to just say class P since we have no time frame.

 

[Vzearr]

Maybe but I'm not sure, we'd need a second CGM opinion there

Can you summarise what needs to be evaluated?

 

[Dalesean027]

Can you summarise what needs to be evaluated?

they were wanting to know for just calculating the energy per second generated by the galaxy outside of using every star in a galaxy should we also be considering the black hole in a galaxy for energy generation as well

 

[Vzearr]

they were wanting to know for just calculating the energy per second generated by the galaxy outside of using every star in a galaxy should we also be considering the black hole in a galaxy for energy generation as well

I believe we should be yes.

 

[AyOgUyS]

At the very least, the Galaxy scaling via the Nebula Fragments is pretty blatant so I agree with it. I'll leave it up to more knowledgeable members to decide whether or not the other stuff is alr.

 

[Greatsage13th]

I finna agree with both options.

 

[Lou_change]

I mean to further support this the terraria bestiary uses the terraria the term god a whole two times one for the name of the torch god an unknown being who goes undefeated and is implied to have let the Terrarian live do to them being willing to grant them favor. The other use of the term is saying the Moon Lord is practically a god and his power knows no limit. Lastly there is one use of the term goddess referring to the Empress of Light who during the day at full power can one shot the Terrarian better then the skulls, doing 19,998 damage at the base difficulty with any projectile. To my knowledge the only other time gods are referenced outside the bestiary is them creating the world I don't think these statements are meant to be taken lightly.
Source
I agree to them scaling to the power of the galaxy.

 

[ObberGobb]

Would the Uni scaling be Low 2-C or 3-A?

 

[Dalesean027]

low 2-C for threating the fabric of terraria (the universe)

 

[Lou_change]

The fabric thing might be questionable the definition of fabric used is most likely the third shown here, the structure of anything. Given Cthulhu was after the power of the planet Terraria I think it makes more since to say it's just the planet. While Terraria is used to refer to both the planet and the universe I would argue it is similar to comic books referring to the universe as earth, an earth or earth [insert number].

Its not used to refer to the planet at all, we went through its uses above they only use it (Terraria) in regards to the universe

how they refer to terraria itself, again i.e "Terraria Universe", The "World of Terraria" or statments implying higher size "Each world of Terraria". This is just all to say again when they reference terraria as a whole they mean the universe

 

[Lou_change]

Bolds and stuff in parentheses added by me this is a copy of the lore text otherwise. I would argue around three examples for each.

Welcome to the World of Terraria (This use is just to give use the proper name, but also it is called a world). A land full of mystery and wonder, with much of its destiny left up to the wildest imaginations... however, a few legends of old have made their way to our present time. Passed down by countless generations of the Order of the Guide, these few scraps of information will serve to help you navigate your journey and overcome threats lurking in the shadows. This knowledge is now passed on to you, the brave adventurer, with the hope that it will aid you in your quest to save our world...

In the beginning, the Gods established a balance to guarantee fairness for all living creatures. This balance was to be of paramount importance, with no cost too great in seeking its fulfillment. Eons have passed since the Gods first began testing the complexities of life in their fairness experiment. In this process, countless living worlds were created and now exist within the Terraria universe (This use refers to the universe). Each world of Terraria is a sentient being that knows all that goes on and can feel the thoughts of all living creatures: with their sole purpose being to ensure that the desired balance is maintained – often violently so (This use is defined referring to the universe). The worlds utilize many defense mechanisms to ensure the balance is upheld at all costs – some of them are known as the Hallow, Corruption, and Crimson.

The Crimson​

The Crimson is a single emergent living being connected directly to each world, sharing a hive mind, and solely focused on restoring balance at all costs. Thousands of worlds before the one on which you stand now have been absorbed by this being. Many misguided people have made the horrific mistake of raising the Crimson to the level of a deity – conducting human sacrifices to it to placate the monstrosity or seek its favor. The Crimson gladly consumes these bodies, becoming one with them and producing terrifying beings, who lose the ability to feel and blindly follow the hive mind.

The Corruption​

The Corruption is a cancer caused by the sins of those living in the worlds of Terraria (This use refers to the universe). The vile actions and thoughts present in all beings feed the growth of the Corruption as it spreads relentlessly across each world. The Corruption knows nothing else but to consume everything it touches, leaving behind terrible creatures of hate that exist for the sole reason to cause pain in punishment for the unearned pleasure experienced by living things. After the Corruption restores balance to life, it destroys it with the goal of turning the world into a desolate abyss void of life.

The Hallow​

The Hallow, on the other hand, is of an entirely different nature. Within each world is a Guardian who serves as the worlds master and core. Once this creature is destroyed the world will release the Ancient Spirits of Light and Dark to expedite the process of finding a new Guardian. It is here when the Hallow is created and functions as an overcompensation of purity, taken to the absolute extreme. The Hallow cures threats that would attempt to violate the critical balance of life, killing anything in its path as though it were treating an infection – whether friend, foe, or neutral party. Ultimately, the Hallow serves to push back against the never-ceasing encroachment of control.

Your World​

It is against the backdrop of this precious balance of life, desolation and pain that the great battles of legend and the adventures of our time take place. In the blind spot of the universe, there exists a planet of unprecedented potential: your world!

Your story begins with Cthulhu – a creature of immeasurable power and unknown origin – who arrived long ago with its seemingly sole purpose being to rain destruction on and to have dominion over all the sentient life that flourishes on your world.

None could stand against the advances of Cthulhu. The very fabric of Terraria itself seemed on the precipice of doom (The universe and the world both work here). At last, when all hope seemed lost, the ancient race of Dryads arose to wage battle against Cthulhu. The Dryads, with their unparalleled connection to the planet, were Terraria's truly last hope as they joined together to save all life from annihilation (The universe and the world both work here).

The Dryads were alas unable to kill Cthulhu. However, with the Dryads combined power they were able to cripple Cthulhu's ability to wreak further damage on Terraria by ripping out Cthulhu's eyes, part of its skeleton, and chunks of its brain (On the universe technically works but at the moment he was only trying to destroy the world and on the world likely makes more sense). Ultimately this substantial damage forced Cthulhu to retreat to the dark side of the moon, where it dwells to this day, gathering strength for another attempt at total conquest. As for the Dryads, sadly, all but a single member perished... and the sole survivor has not been seen for many, many years.

Lunatic Cult​

Much time has passed since the Great War of Cthulhu. However, rumors tell of a Lunatic Cult led by a fanatical zealot that is methodically seeking to revive Cthulhu to its former power and bring about the end of the world. As a part of these efforts, a renowned genius – known simply as the Mechanic – has been kidnapped and forced to rebuild the parts needed to make Cthulhu whole once again. Hushed whispers tell of the results of these experiments: horrible mechanical simulacrums of Cthulhu's organs. The Mechanic has nearly completed her work, only needing to finish the Mechanical brain to restore Cthulhu to its full destructive power.

Passing travelers hear construction and screams emanating from the Dungeon – an evil, demonic fortress of the dead in which the Mechanic is supposedly held prisoner as she conducts her work.

Many across Terraria have fallen under the possession of the cult, including the benevolent Old Man who oversees the Dungeon, a once thriving city full of life until a curse forced all its inhabitants to go mad – living beyond the point where their bodies rotted away and they became mindless undead servants of evil (I don't think they have space travel they had to kidnap a mechanic this is probably referring to the world). Without some intervention, some force to stem this tide, some hero to save the day, Terraria's doom is nigh at hand (the cult is only explicitly trying to destroy the world not the universe but either works)!

This brings us to our adventure. It begins with you – in humble beginnings and shown your path by the faithful and mysterious Guide. As this world's champion, you will experience communications from the world to help protect your mission. The world has brought you to this specific location at this specific time – will you stand up and fight for Terraria against the growing shadows of impending doom (The world brought you here but it could still be either the universe or the world)?

 

[Dalesean027]

Welcome to the World of Terraria (This use is just to give use the proper name, but also it is called a world).

Not uncommon for universe and world to be synonymous in this case, its in fact very common that lots of series do call it the world and universe,

Terraria universe (This use refers to the universe). Each world of Terraria is a sentient being that knows all that goes on and can feel the thoughts of all living creatures: with their sole purpose being to ensure that the desired balance is maintained – often violently so (This use is defined referring to the universe).

Yeah another instance 2 of which back to back which refer to it as the universe or at worst a structure containing numerous worlds.

The Corruption is a cancer caused by the sins of those living in the worlds of Terraria (This use refers to the universe).

Third one

The very fabric of Terraria itself seemed on the precipice of doom (The universe and the world both work here)

again in this case world doesn't have to explicitly refer to planet as many fiction switch using both synonymous as meaning the universe.

Your story begins with Cthulhu – a creature of immeasurable power and unknown origin – who arrived long ago with its seemingly sole purpose being to rain destruction on and to have dominion over all the sentient life that flourishes on your world.

this is the only one that outright says your world (as in the planet) but it also doesn't say Terraria in reference to anything larger which works again as evidence that when mentioning "Terraria" that is again referring to the universe.

the rest kinda all follows that where world and universe can be swapped or synonymous
