Our obsession with the multiverse is partly why D&D's Planescape is coming back

gamesradar.com:

Planescape for D&D is weird. Actually, that's the point. Traditional fantasy takes one look at it before turning around on its heel and wandering off for something more sensible.

With Planescape: Adventures in the Multiverse bearing down on us in October, we caught up with the team behind it during Gen Con 2023 to see just what the hell is going on with what is arguably one of the most bizarre settings in D&D.

If you're new to Planescape, forget everything you know about Dungeons and Dragons books for a second. Created in the '90s and relegated to cult-classic status after the setting was dropped (though a certain video game of the same name kept its legend alive), this isn't your average swords-and-sorcery world. As designer and Planescape lead Wes Schneider describes it, the setting is cut from the same cloth as stories like "Doctor Who, or Everything Everywhere All at Once, or Loki… this is mind-bending impossibility, tampering with what we know as the laws of reality, and shattering them."

Basically, Planescape revolves around a city called 'Sigil' that squats at the center of the D&D multiverse. However, this isn't your standard-issue medieval city. Instead, it's more like the Citadel from Mass Effect; it's a floating ring with a thriving metropolis running along the inside. It's also a nexus point that can take you anywhere. It's known as the 'City of Doors' for good reason; it's littered with portals to every setting in the Dungeons & Dragons franchise. Schneider describes Sigil as "the ultimate hub. It's any adventure you want to have literally anywhere in D&D. Any place else you can imagine is one step away."

There are people from literally every world living in Sigil, and that means tensions can run high.
