This quest, which occurs on Khenarthi's Roost, the starter zone for Dominion characters, is bugged. In one sequence, you are given a choice of drugging a guard or forging a letter from his lady, to draw him away from his post. However, the Inkwell and Blank Paper on the desk in the bottom hall can't be interacted with. The game SAYS they can, but interacting with them does nothing.
I filed a bug report in game, but I'm posting this for the sake of completeness.
