Name that Demiplane!

[Irthos]

Evenin' folks. I'm trying to dig up a bit of Pathfinder lore to share with a friend, but I can't for the life of me remember which book it was in.

The lore concerns a demiplane, which I believe was in one of the campaign setting books. This particular demiplane consists of winding stone passages, all leading to a central cavern where the plane is slowly crumbling into an anomaly that's acting sort of like a black hole. The plane also has two statues in the caverns, sporting a vaguely ominous inscription that references being nobody's heard of.

Does this ring a bell with anyone? I've been poring through my collection trying to find this reference, and I'm starting to think I imagined the whole thing.

Have tried checking Planar Adventures?

The place you described in your post doesn’t ring any bells. Not with me anyway.

Don’t have my books handy right now, but it kinda sounds like a mishmash / vague recollection of the various features of Abaddon as detailed in the “Great Beyond” Pathfinder Chronicles book.

Working from memory but I believe there was a whirlpool at the center of Charon’s domain. And at the very heart of Abaddon, through winding passageways, is the body of the Horsemen’s progenitor deity. (Can’t remember the name but s/he was to the Horsemen as Cronus was to the Olympians.) The corpse speaks truths that no one has heard (or something like that.)

It might be worthwhile to comb through Pathfinder Wiki's Demiplane category page.

That sounds similar to Pandemonium, but that would be the Great Wheel rather than Pathfinder cosmology.
