The hideout on Caste Lane is a ram-shackle two-story warehouse. The Black Newtowrk has other sanctuaries in run-down buildings like this one throught Waterdeep.

The warehouse stands at the back of an outer yard behind a high fence. The gate on the fence isn't locked. The building's three points of entry-a front door, a large warehouse loading door, and a painted-over window-are locked. The front door has a sliding peephole that can be opened from the inside.
