speaking of which ... 'Siege of Eternity' sounds like a fitting title for this WW game 
In all seriousness though, upon further introspection, I don't think its possible that Rowain is a wolf.
Namely, unless there was a NIGHT-kill IMMUNE multi-shot vigilante (at least 2 or 3 shots) I see no possible way for a lynch-immune wolf to be balanced.

of course, we shouldn't stop just there. Its possible that it was either a 1-shot thing OR it was an activated power by someone else. Remember that power in WW11 where someone activated it and it was impossible to lynch the leading candidate? Maybe we are seeing a power like that in play.
Granted though, assuming it was, even a 1-shot lynch immunity ... I think we can pretty much nail Rowain's innocence at this point in time.
