So, Dark Sun tends to touch on the outer planes lightly, but you get occasional sightings of out-and-out fiends (usually mad because they’re stuck on this ball of dust and rock).
But what about Upper planar creatures? What would it look like for an Archon or Deva to be dragged down to the sub-Prime material plane and stuck there for a couple centuries?
