When/how does the Thieves' Maze become accessible? I'm in Chapter 7, but the staircase in the Thieves' Guild still doesn't go anywhere. I've talked to Niklos and he's told me that Alatos has "gone underground" (or something similar to that), which seemed like a clue, but I still can't get anything to happen. I've also had Imoen search the whole place, with Detect Traps skill of 90, and no secret passages turn up.
