The Hillingdon clan has the hunters. Sorry I just didn't put it all together till after sleep. There's no real leader but they help outcasts and people fleeing from supernatural problems so there's no reason they shouldn't help a rouge military guy. They're not really run by anyone but they have a mentor thing going on. Hunters are Level 2. There's NPC clan leaders that are shape shifters. As well as some unknown faction leader. So that's who would have worked with Jensen's boss to place him there. Might be interesting if the bad guy from your series made a deal with a fae to keep himself hidden.
