Notes:

Arbin is ready to start a counter attack. He sends you to Ghanlin again for instructions on how to procede. Ghanlin tells you that you need to start by killing a few of the skeleton tunnelers. Once they are dead move south and then east to the former headquarters of the Knights. Inside you'll find a bunch of heretics including a commander and a hierophant, kill them, loot their heads, and deliver them to Arbin. Chat with him after to complete the task.
