Interesting... what you have found here is a water-proofed, leather tube containing a number of sheets of parchment. By the markings upon them, the pages are clearly navigation rutters, and each bears the signature of one Captain Kelisendra.
You've heard of a small, defended camp just east of the nearby Sunsail Anchorage. Maybe the captain is there?
Hello, <class>, you're a sight for sore eyes. I know, it's crazy for me to be here, what with the anchorage overrun by the Wretched. Velendris and his rangers have sworn to protect me on the condition that I get out of here as soon as I've recovered my cargo.
What's that you have there... it looks vaguely familiar?
Oh you sweet, sweet <class>! I had no idea that those disgusting Grimscale murlocs had also pirated away with my navigation rutters! Without them, I would have no chance of navigating the seas again once we retake the anchorage and repair the ship.
Thank you very much! Here, take this coin as a sign of my appreciation.
