The werewolves are just starting to go on the offensive now because they’ve gotten tired of waiting on him to cure it. It seems that Zathrian is responsible for the centuries long course in the forest.
Regardless of your plans, agree to be taken to their Lady of the Forest for a brief parlay. Head down the steps and you’ll meet the gatekeeper. Once again, you’ll face about six or eight werewolves and you’ll just have to keep fighting. You just have to use crowd control attacks or abilities and pick them off one at a time.
As you fight them, another four shadow werewolves should pop in and join the fight. Go down the steps and you should find four werewolves.
