Rift
Rift-Realms are planes native to the Rift, not external universes. They are persistent regions of the Maelstrom whose local “physics” are set by specific Devotion profiles (color configurations) and reinforced by the souls, gods, spirits, and entities that dwell there.
Mechanically, each Rift-Realm can provide:
A planar trait package (environmental rules, hazards, and boons) keyed to its Devotions.
A distinct set of native creatures (outsiders, spirits, fey, data-ghosts, etc.).
A set of planar bleed effects that occur where the realm pushes into Real-space.
Rift-Realms explain why magic traditions, outsider types, and afterlife myths vary: they’re all tapping different “addresses” inside the same psycho-reactive dimension.
