Trireme Stranding Camp (Location)
You'll raid this imperial post in Uab Nome during the Jaws of Sobek Side Quest.
Approaching from the water puts you in good position to pick off the outer guards.
Work your way around the outside, southerly edge of the camp, until you can enter the captain's tent from the backflap.
Once inside, the oblivious captain is to your left, waiting to be assassinated.
Loot the red chest at the other end of the tent to complete the location.
