It is recommended that you are at level 15 or higher before attempting this, as there will be better armor and weapons inside. Travel on the west road from Leyawiin and keep walking on the trail until you get to Waters Edge (a small town). From Waters Edge, walk northwest until you reach Rockmilk Cave. This cave is very close to Waters Edge. Go inside and follow the trails. You will encounter some thieves inside the cave. If they do not notice you they will fight each other. You can let them fight or join in. They are not difficult to defeat if you are leveled up. Go through the cave and you will find at least fifteen people inside. Each of them has their own set of Glass, Orcish, Daedric, or Elven armor and weapons. You can fill up with items and sell them for a good profit.
