Undead Pirates

I traveled back to the Buried sea with some companions and continued helping Gus Longear with his investigations into the shipping lane problems around Deadbone Ilseland. On previous forays to the ilse we determined that it is not the wildlife or the natives that are causing prolblems. This left the undead. After fighting our way though numourous drowned pirates, we disturrbed Rum Red, known to be a lieutenant of the infamous undead Kenox. Despite his control of pirana in the waters we defeated him and took this information back to Gus. Gus sent us back to talk to the native shaman Maatha Wirrigan to find out a way to awaken Kenox so that we could confront him. Maatha instructed us to collect 4 special pearls to create a tailiman. We did so and then returned to Gus. Gus then sent us to confront Kenox. We awoke him and defeated him, hopefully clearing up the problems.
On our way back though Barren Coast we were contracted by Captain Zeke to protect his Merchant ship. Not long after we left the coast we were attack on the open sea by a ghostly ship under the command of Captain Undertow. We were able to repell the boarders and force the ship away, but this lead me to believe that maybe Kenox was not completely defeated.
