He has some personal problems, unfortunately. Inner turmoil and all that. I can't say more without giving story points away! He's such a fun character though, and I just wish I hadn't made his design so painstakingly packed to draw as he's far more involved in the story than he was at the start!
DAMN YOU FELIX!
As an aside, the otterface and I are thinking about possible Fenra merchandise, and would really appreciate some feedback if you guys can spare a few minutes =)!
