No online guide yet. Find the stairs (only one set that is not behind locked doors). Go down until you find a way to go either west or north, then come back up to see if the thieves are around. Good luck!
i found the stairs, inside is 2 other sets of stairs, one going down and one going up, i choosed the one going up but i went to a small open area with "R" and a "K" and nothing else
