Personally, I'm kind of hoping the problems with Y'shtola and Thancred are either resolved, or we see some means to compensate for them. Maybe Matoya will pass on her crystal to Y'shtola so she doesn't die in a few months time. As for Thancred, maybe he'll tame a Griffin and use that to get around?
