Shield of Arrav no longer needs 2 people to perform the quest. Every direction in the walk through is correct except for the part where you need to exchange keys. The player joins each gang (by looking at my completed quest, it doesn't seem to matter which one is joined first?) and needs to grab both parts of the shield (one half from each location). The player puts them together and then talks to the museum curator. The museum then points the player to the King to claim the bounty. The reward is 1 quest point, 2 prize keys, and 12,000 coins. EDIT: That might also mean that the tip is no longer applicable (gang membership persists). I am not sure how to test that.
