[There's no time to ask questions or wonder about the change in surroundings, the unfamiliar place and the undeniable weight of magic that must have brought him here. Before he can ever get far, Fenris is faced with monsters -- and really?]
Should I have even expected anything else? [No time to waste on the thought, he draws up his weapon to hack at some incoming creatures THIS IS FINE maybe killing some things will help him figure out where to go from here. Or get some much needed stress relief.] Come and face me then!
[If you don't find him fighting already, next best chance is that he'll suddenly jump behind whatever creature is about to pounce on you, and kill it before it does any harm. It's a move that leaves behind a lingering white-blue flash, a glow from his tattoos. Not that he's being nice or anything hrmmm.]
It leaves a bad aftertaste as it is, to watch another person mauled for no reason.
