Nile Wharf (Location)
An enemy location and fast-travel spot in the Theban Necropolis.
The treasure is in the middle of the encampment, but the captain does pay a visit to the isolated piers from time to time.
Even if he's not there, the low structures and low headcount of the camp make him easy to snipe. When he's gone, approach the central tent. You can do this sneakily by using the backflap hidden in the shrubbery.
Loot the chest inside to complete the location.
