Yeled:Not to hijack the thread, but why won't you get Werewolf? And what prompted the purchase of Wolf's Bane?
Yeled: As for the reaction of werewolves...I suppose they would probably take note of it and watch it and make sure it doesn't do anything bad, but otherwise leave it alone so long as it leaves them alone. A particularly zealous or paranoid pack might try to take it down due to its nature as one of the Idigim, for precautionary reasons. But I don't think most packs can afford to look for trouble where there isn't any to begin with. So I think most would ignore it or maybe try to drive it off or reason with it (if such is possible). I don't know if they would treat it much differently than they would most other spirits that aren't harming anyone.
Shock:you can leave it alone for a little while as you deal with more pressing issues (like that Pure pack that is trying to bite off a piece of your turf) but eventually an issue will come up that will make you regret ever leaving him alone in the first place.
StSword:Considering the forsaken's role in the universe, it would have to be an idigam that doesn't mess with the physical world, or the forsaken would never be non hostile to the spirit.

Which would eliminate it being a 'benign' Idigam. The premise that the original poster was presenting in the first place. Keep in mind exactly how difficult it is to eliminate an Idigam, a single pack is not going to be able to destroy it. Which assumes that you even recognize what this thing is in the first place. A truly benign Idigam is more then likely going to be completely invisible to everything.
