[ Y'know, the difference between mortal bodies and other bodies isn't really all that strange. He's familiar with other kinds. ]

I dunno- Were you some person made of magic, or dead? It might not count as a body, which is probably one of the created rules for this Mirrorbound thing. Also, given this universe has a rule about people not having powers, and instead the kind of magic here, I pointed out that being the relevant change. It's not changing the body, though it'd cancel out a lot of what can be done, if you were expecting that.

[ Is your body how it should, if you were a person before then? ]

How different is this body, than how it should be if you had one in your universe?
