Speak to Divemaster Birmingham in Glimmerdeep Gorge.
Poor things. They're starving.
We've many matters to attend to, not the least of them the naga, but first we need to get some food in these bellies. I'm not sure what the naga fed them up in that shell, if anything, but they're definitely worse for the wear.
Quite a few of the survivors have made their way into Glimmerdeep Gorge, to the northwest. Go join them and help out. With a bit of clam meat, we can get these survivors back on their feet.
