I mean... you need to find his jacket (an useful artifact, actually - if I could find werewolves), whip and hoop and return them. Trouble is, you can only do that after you have gotten a boat, and you can only get a boat on the first island after you have beaten Eric, and after you beat Eric, you are exiled from the village and can't enter it...
So, is there some way to get back and complete the quest later? I could use those runes...
