Search for the Tear of Ashi.

Once you have collected all the pieces of the Shantiir disk in one hero’s inventory, the map should show you the location of the Tear of Ashi. It seems you missed it. If you have the entire map revealed, scan it with your eyes – the Tear looks like a golden chest with a pillar of light. In this mission, the Tear is located south of the first town you encounter, slightly north of the fort controlling the barracks.
