Very nice start, Vaast is very likeable personality wise and a nice blend of classic wolf-man with something a little more alien and exotic. ;) I am curious to learn more abot our MC and his background. He seemed really good at coping for someone in as stressful a situation as his - perhaps another 'gift' from the doctor? Looking forward to read more with the next update.
And being Vaast's chewing toy doesn't sound all that bad. ;)
