- Secret Errands - Scarlett must have completed this quest by stealing the Chimney key from Largo, without killing Mercutio. (If she previously killed Mercutio, this quest is not available.)
There are two lairs that Scarlett must clean out:
The first lair (1) can be found by walking along the canal on the main level of the Arsenal District, south of the canal but north of The Platform. That will land in some arches, and through the arches Scarlett will find a set of stairs leading up to a small landing. There is a single door here, and that is the first lair.
The second den of thieves (2), is found by starting up the main stairs back by the Ambrosial Loutus. They quickly lead to a covered, ascending corridor. Before that covered corridor ends, there is a single door on the south (left) side, which is the second lair.
