Nearby there lies a cave which was used by a band of thieves with more stealth than strength. They had stolen a large quantity of art, and has stashed it there until they could sell it off. Unfortunately, a group of Banderlings wanted the cave for their own. The paintings may still be found there. Head southeast along the road, past the lifestone. You will see a bend in the road with a tree. Walk outwards in the direction of the point of the road - a series of yellow flower bushes lead into the forest. When you come to a clearing, you should see the portal.
