Hey, #4 after the bow training with the Orc Teacher just talk to Mael #17 In the vampire villa in the reading room to find the key. You have to search around, I think it was behind the painting or behind the books(I can't trigger the event a second time after I found it). You're welcome ;)
It's on one of the little squares at the back of the room during the "hidden object" part of the manor. If you don't find it I'll send you a screenshot
