Brig explained most of it, just doesn't understand what's wrong. He took it all because he assumed I would never come back, even though I had told him not to. He's repaid me for what he took, although it's a pain in the ass to find it all again, you know.
He's also going to help me get the piece of the Hyunmu set that I'm missing, but that requires me going along, which is what? A pain in the ass.
