I think I've figured out things Cosmologically;
Each world is a
reality, that much is stated, and the Wild Route, where we basically become the world,
tells us that we have no beginning or end. It is also
stated that every decision we make sends
us down a path to see entirely different worlds.
In the Stranger Route, we are shown just how many of these paths exist. Each
step on a staircase, branches into another staircase, and their steps branch into another staircase, and each of those steps branches again, and so on and so forth. These staircases are
described as patterns, and these
patterns are stated to be endless.
Because of that,
everything is described to happen at once on the Stranger Route. It is confirmed there is
no beginning or end to the number of Princesses when the Player goes on the Stranger Route, and in every moment they hold every possible sensation, and then the next moment they hold them all again. At that
moment they were everything.
So basically, there was an Infinity ^ Infinity of worlds on that route, and it's stated that all happened, in a
single world.
Moving on, the Multitude is also stated to be infinite, with a Princess like the Wild & the Stranger still just being fragments to her. The Multitude is stated to exist within the Long Quiet, as once the world is 'destroyed' in any scenario, or simply vanishes due to the Princesses influence, it's all we see.
The Long Quiet is also stated to be an endless nothingness.
Then you have the Construct, which is stated to exist in multiple places at once. This is because the Construct exists in every world, on every path, and contains the Multitude and Long Quiet. We know this because it's the reason we come back to life every time we die, and it activates on all routes, no matter which one.
It is described as having infinite sides and angles, with even the Wild which was essentially endless, needing to exert itself beyond its limits to find its end and create the smallest hole in the construct.
Next, you have the Awakened Long Quiet & Shifting Mound. Just like the Wild, it was stated the Construct limited their size. However, we learn this is only because they believe they are limited by it. Their only limits are the ones they set for themselves, so the moment they stop doing that, they break free.
Lastly, you have the absolute reality, which is stated to be infinite and endless, something outside of the Long Quiet & Shifting Mound.
Still despite being outside of them, awakened the Long Quiet & Shifting Mound are capable of reshaping absolute reality as they please, making up new rules, and are no longer simply at the top of the pecking order, they become the pecking order.
So, what do you guys think tiering-wise?
