You know I think the Seneschal is straight up Low 1-C using DD1 alone. Although the current lore seemingly indicates there is a Seneschal for each universe instead of 1 overall Seneschal...for now, the lore also repeatedly implies that the Seneschal's Chamber is superordinate to Rifts. To start, I'll present a brief description of what the Seneschal's Chamber is according to a
scan from the official art book:
"A space that exists outside of time, sandwiched between dark heavy clouds, or a realm where notions like up and down have no meaning. From pitch blackness to blinding whiteness, everything about this realm is within the control of The Seneschal. Unbound by the laws of physics or even common sense, sunlight can shine through any part of the clouds and lightning upwards from below."
For those who don't know the TL;DR on the Dragon's Dogma cosmology its this:
The world is composed of parallel universes stacked on top and below each other endlessly all connected by the Everfall and can "only" be traveled between by the pawns thanks to the Rift (
34:46)
Each universe is infinite in both space and time and exists eternally in a loop.
"The pawns exist astride the rift. They speak of a multitude of worlds, each infinite unto itself. Limitless in span and lost to time, these worlds extend in an eternal, perfect loop. Just as a ring lacks start and end, so this world has no origin, no final terminus. If it does, they lie beyond our ken. We are prisoners of unpassing time, wandering an unending land. What lies beyond, we cannot know."
"Aye, there is life in the world, and with it death. Naught lasts forever. Each rises and falls in its time. But such is a death akin to that of pawns. They appear in this world, then vanish only to appear again, like bubbles in a mountain spring. As so it is with all that lives within this eternal world. In time, you will come to see it happen under your watch as Seneschal. Each beast, each blade of grass, each human life is born to die and be born again in endless rhythm. Naught lasts forever, yet all persists unto eternity."
Within the Seneschal's Chamber pawns have various dialogue that expresses its' grandness and likeness to the Rift which is a rift
space between the worlds (due note that Rifts are both plural and singular but essentially refer to the same space/realm/dimension etc in-game):
"This place is ...familiar."
"It feels different, yet..."
"
This bears the look of ...Of the world beyond the rift."
"Even we who traverse the rift do not ken what lies beyond."
"Rifts are but gateways linking distant places...slivers of a world far more vast.".
Pablos (The Cassardis innkeeper) also gives us dialogue related to this idea:
"A traveler told me a most curious tale.. He spoke of a hole beneath the capital what leads beyond the rift"
Furthermore, we have pawn dialogue about the Everfall after defeating Grigori, the Everfall becoming the infinite tunnel that ultimately leads to the Seneschal's realm which really cements the idea that was brought about in this post:
"We stand at the trunk of all the branching worlds. The very root..."
"'Tis shaft is the axis along which all turns... 'Tis the source."
"We fall, and fall beyond...".
Now, with these chatter dialogues in mind, it's pretty simple to piece together the Seneschal's Chamber's scale in comparison to the Rifts.
Rifts are spaces between the universes and are gateways that connect to other universes. Gateways that are nothing but slivers of the far more vast world being the Seneschal's realm which exists beyond Rifts in its entirety yet is similiar to the Rift. The Seneschal's Chamber is a realm that exists outside of time, unbound by the laws of physics, and is under the complete control of the Seneschal. A space that can only be accessed by traversing the Everfall, the very root of all the branching worlds and source in which all turns, by collecting the proper amount of Wakestones to open an abnormally powerful rift to the Seneschal's chamber.
I firmly believe this would indicate that the Seneschal's Chamber is at least Low 1-C in terms of dimensionality. The Rift being the space between the infinite parallel worlds and the gateway that connects them all makes it a 5-D structure in terms of size. Seneschal's Chamber being described as the world beyond the Rift and while within the Seneschal's Chamber pawns, describing Rifts as being merely gateways/slivers of a far more vast world would indicate that the Seneschal's Chamber is likely 6-D in terms of its dimensionality. Naturally, since the Seneschal's Chamber is Low 1-C, the same applies to the Seneschal who has complete control over it.
Now I know those familiar with the verse would have concerns regarding this idea. Concerns such as "If the Seneschal is Low 1-C, then why do they only have control over one universe?" and my answer to that is simple, the Seneschal can be Low 1-C while being limited to their universe. Similar to how the
Infinity Gauntlet can be Low 1-A in all aspects but only functions within its own universe or in the case of the Seneschal, they're Low 1-C within the Seneschal's Chamber and their universe.
Although I would really love to make a CRT on this topic and add DD profiles back to the wiki, seeing as DD2 is close to releasing and would undoubtedly affect these proposals, I'll just wait until then. Hopefully, my fire for this verse on this wiki will continue to burn by the end of my playthrough of 2.
