The only thing i have found so far is at 429, 336 in the bedroom under the bed there is a hidden door that appeared for me but i havent figured out how to move the bed, probably because i haven't talked to that girl. Im at the point where ive spent 6 hours wandering around the city blind. after 50+ hours i have come to realize that there are too many quests in this game that you have no idea if they're done or not or where to go next.
That being said, i have the amulet charged, but havent figured out the scroll, because despite having gone into the vault, i never got to ahru.
