A dead robber near the throne, and the trail down

There's a new side quest, and no one gives it to you — you just find it. Search near the throne and you turn up a dead robber with a tattoo Grey knows: the Order of Dusk, a guild that hires out for murder and theft the world over. Two of them made off with the temple haul, fell out over the split, and one fled wounded and died before he reached the hideout.

Follow the trail down and it runs through four fights to a hidden grotto camp at the bottom. The things you meet down there have an undead feel to them. See it through and the reward is a proper hoard — a stack of Oak Bark and Quartz, plus fifty each of the game's shop materials, so basically one of everything the shops sell, handed to you as crafting stock.
