Awesome character, [@pantothenic], and I'm seriously digging the religious angle, which hasn't really been focused on as much as I'd have hoped so far, and his use of the Tethering. He'd have unusually fine control and very long drawing and casting range. His progression of the disease is also considerably on the low end of where most people would be by sixteen, as he's still ambulant, so perhaps some sort of remark about how some people maybe even believe that his fervent faith is pushing back against the disease, delaying it? 

I also imagine, given his personality, that he might want to explore binding at some point, genuinely for the sake of healing as opposed to most others' ulterior motives. In any case, he's great and I look forward to having him in the RPG. Pending whatever little tweaks you see fit to make based on this advice, feel free to pop him into the characters tab and do an introductory post. We can discuss a way to slip him into the current arc if you like, either with the groups or staying back with Hugo, Jocasta, and a few others.
