Kingdom of the Cleansed Quest
In this quest you’ll meet Tristian. Eventually, he’ll come to your throne room and tell you about some cult member who has come to town. Go to the town square, find Tristian’s icon on the map and head for it. Talk with the girl standing next to him and then with Tristian. After that, open the world map. Move to the right and down, away from the capital and towards a new location – Secret Sanctum (it’s below the bridge).
After arriving at the place of ritual and investigating it, start a fight with the worshipers and a man in a hood. First you should kill him and his assistant, and all the others will run away. A mysterious man will threaten you with a Goddess and disappear. Now you only have to go back to the town square, find Tristian and talk with him. This will end the quest, and you’ll get 900 XP.
