The Weynon Stones are a landmark located between Korvanjund and Fort Dunstad, just south of the path.
As you enter the circle of stones, two ice wraiths will appear and attack you. There is an altar with a statue of Talos depicted as a warrior with a dragon coiled around his feet. There is a shrine of Talos on the altar. There are also two steel ingots, a pair of steel Nordic gauntlets and a broken axe. Across from the altar is what appears to be an offering table with a large stone head above it.
Behind the altar rock is a chest with a novice-level lock containing random leveled loot.
