D&D: Planescape - Adventures in the Multiverse

Infinite realms of immortals and impossibilities, the Outer Planes brim with celestials, fiends, gods, and the dead—and they’re all just a step away. Enter a portal to Sigil, the City of Doors—an incredible metropolis where portals connect to every corner of the multiverse. From there, venture to the Outlands, the hub of the Outer Planes, and discover wonders beyond imagination. The possibilities – just like the realms – are endless.

Planescape: Adventures in the Multiverse comes with a plethora of new player options and provides Dungeon Masters everything they need to run adventures and campaigns set in Sigil and the Outlands, including adventure hooks, idiosyncratic locations, and multiversal calamities.
