Yes please! I'd absolutely be down for Feydor trying some healing on him, and Dorian would be very thankful for any way those scars can be lessened (and the books). His body is his temple and all those imperfections are going to be a source of some discomfort for a bit.

Callisto claimed that corpse but it looks like she left it there, so I wouldn't see why someone else couldn't stumble upon it as well?
