In the rotting remnants of the Dwarf's leather purse, you find 56 gold pieces and 7 gems worth 3D6 gold pieces each. There is also a battle axe beneath the body. The battle axe is magical. It gets 8D6 in combat, and can be wielded with one hand, allowing the user to carry a shield or use a second weapon. There is nothing else of value here; climb out and decide where you want to go.
There is a door in the far wall. You could try it, or return to the intersection.
