There is an enemy ship nearby that isn't answering any hails. Since the magistrate doesn't currently have the manpower to fend off a siege, he suggests that you slip aboard at night and take out the Captain and his first mate.
A Swashbuckling mission on board of a ship against level 18 opponents. The main problem in the beginning is that there's a lot of enemies in a very small space, so you will have to pick your fights carefully if doing this mission solo. Once you've thinned out the crew a bit, it's not hard to reach the aft deck where the Lieutenant is waiting with two guards. Take out this group and a level 18 Boss spawns in the same spot (again with two guards).
