The quiet hand that keeps House Slayton from collapsing completely.
Gregor Snow is the first born son of Godrik Slayton. However, with the identity of his mother unknown to everyone but his father, he is seen as a bastard. This is especially unfortunate, as all of Gregor’s brothers and sisters are incompetent leaders with the possible exception of the Snow Spider.
So instead of being the Lord of House Slayton, Gregor is the Captain of the Guard instead. He serves on the small council and while his influence in Cliffside is vast, he must walk softly in the outside world lest he overstep the social boundaries of being a bastard son.
In essence, Gregor is a man restrained.
