Gorbold Steelhand at Lor'danel wants you to speak to Gary for further instructions.
You look like an able sort!
There are a great number of wrecks off of the coast here... most old, some new. For quite some time, I've been trying to get at their holds and put their valuables to more use, but there's a nasty infestation of murlocs that seem to have other ideas. I've sent scores of adventurers and none have returned.
Worry not, I've learned my lesson, and that is not your fate. Swim to the due north and look for Gary. He'll explain the new plan. It's pretty simple really.
