Astulae

A campaign setting in a twisting megadungeon of alternate realities.

Imagine that your dungeon is not a series of rooms connected together with cobweb-ridden corridors deep underground, but instead, each “room” is a splinter of reality taken from across a grand ensemble of possible parallel realities. Every Astula (a room) can have its own laws of physics, its own peculiarities, and sometimes: its own denizens – some benign, some deadly, and some incomprehensible. In some Astula, magic and technology can coexist side-by-side, and in others both are strongly suppressed.
