Dionysias Wharf (Location)
A hostile dock in Faiyum.
A relatively built-up location- the treasure and captain's office are in the large, open-roofed building next to the lighthouse.
Come in from the north, trap the brazier, and drop down through that roof to backstab the captain.
Loot the red chest on the balcony opposite to complete the location.
From the roof of this building, you can also cross over to the lighthouse, and slide down the rope to free the captive rebels here.
