Quest is - Take down Tethyr.  Its a string of quests in theramore.  I wasnt sure at first what to do.  It tells you to control the mortors.  Basically there are several cannons (mortors) on the docks.  They kinda sparkle a little.  Run up to one and click on it- right click when your ready and it fires at the boss.  I think I had to do this from the cannons about 5 times before it died.  I am a lvl 40 shaman and did this alone.  It wasnt too difficult, you just have to be prepared to run alot.  The boss spits water at you so you get blown away.  The xp was very nice- 4350.  Plus you recieve 75 silver and the choice of several items.
