Astulae
by Sequestered Industries

Imagine that your dungeon is not a series of underground interconnected rooms.

Instead, each Astula (a room) is a splinter of reality taken from a grand ensemble of possible parallel realities!

Every Astula can have its own laws of physics and peculiarities, some where magic and technology coexist side by side and others where both are strongly suppressed.
