Dispel? A Cthulhu monster? The old ones are notoriously powerful deities, no? Shoggoths feel like they're counterpart to Yumeiko, only for Cthulhu or whatever. She is sacred of a human deity, shoggoths are "sacred" of some Eldritch horror, y'know?
I was under the impression each room is it's own pocket?
Calling them "deities" feels like I'm falling short.
