Kerke Wharf (Location)
A military location in Atef-Pehu Nome. You'll raid during The Matriarch Side Quest
A sprawling place, but the captain you need to kill & the treasure you need to loot are grouped together in the captain's tent by the shore watchtower.
Approach from the southwest shore. Snipe or sneak the pier guard (if there is one), and the watchtower guard.
Your next kill should be the captain. He seems easily distracted- if he's not moping around the tent, then he may be just playing in water, alone and unguarded. End him either way.
Enter his tent through the backflap.
Loot the large red chest to complete the location.
