We're in something called a Fissure. It's an area of uncontrolled magic, where reality is unstable and the walls between worlds are thinner. People and objects appear here supposedly at random, though the fact that people only appear when there's someone around to find them has me suspicious, and creatures already here can be subject to...unusual effects.

[Gesturing at his...well, his everything, really. There isn't a part of his body that actually looks like it's supposed to.]

In the last one I was in, nobody needed sleep and our recurring dreams were made semi-real. Not dangerously so, but enough to follow us around and display some deeply personal things to others. Both effects ended when we got back to stable reality, though, so it's likely we'll get our legs back when we leave this Fissure.
