According to Dragan, the battle in Tiamaranta was not over yet. He asked you to go and see Governor Skafir. Skafir told you that the battle against the remaining troops from the Tiamat Legion was still going on. She asked you to go to Tiamaranta's Eye for that reason. You met Grimron in Tiamaranta's Eye and eliminated the Drakan Soldiers at his request.
