The god Ralakesh has possessed Greust and taken over the old Forest Encampment. You must kill Greust to defeat Ralakesh. Upon approaching the entrance to the Old Fields from the Crossroads, you will find them blocked. Helena tells of a secret passage from the Chamber of Sins to the Den. The key to this passage is given to you by Silk after you defeat Maligaro in the map device. Maligaro's map must first be found in The Crypt . Continue through the lower level of the Chamber of Sins to the Den and then to the now burning fields and confront Greust.
Ralakesh is located in The Fortress Encampment which connects The Ashen Fields and The Northern Forest.
After the battle return to Eramir to receive one passive skill point.
