Obtain a handful of Slumber Sand, a jug of Fel Slider Cider, and a Clear Glass Orb.
Ariok said he needs supplies? I've got plenty of supplies! Problem is, those warlocks have kicked me out of my home, and they're not letting me back in.

You might be able to get in, though. Head north, and grab some of my slumber sand, my fel slider cider, and a clear glass orb. I'm pretty sure that's what he wants.
Oh, and if you happen to accidentally kill any of those orcs while you're up there, I wouldn't be terribly upset.
