I've heard of vampir that could do similar but- I didn't think that was just something that happened. I thought it was a learned skill.

[ Maybe if he'd finished his training he'd be more use here. As it is, he just has to grasp at what he was able to learn before the executions. He rubs at his bad eye in thought, shifting the eyepatch around as he does (he's willing to take it off in the castle these days but even here he still wears it most of the time). ]

So it just moves around on its own?
