Inside the building are a bunch of people, obviously from rock bottom financial status, shambling about like zombies. These guys are stoned out of their minds. There are a few Rat Livers who are also stoned. It seems unlikely that the boss will keep his gems here. They must be in his room... But which room is it?
On the ground floor, you notice that there are a grand total of 5 doors, not counting the main entrance. Considering the entrance to be on the east wall, there is a hall that is 20ft wide going straight west. On the south wall of the west hall are two doors spaced fairly apart. Before the west hall starts, there are also 2 doors on the north side and 1 door in a niche on the south side.
Tomoe manages to jump out of the way just in time to avoid an avalanche of stacked cleaning supplies. She hears someone say, "What was that?". One of the two doors in the west hall opens and a half-elf with a short french-cut beard steps out. He eyes Tomoe and says, "Who are you? You don't look like one of these junkies."
