Fenarel is a temporary companion in the Dalish Elf origin.
Involvement
Dragon Age: Origins
After the Dalish Warden awakens back in the camp, Fenaral explains that he/she had been rescued by a Grey Warden and was comatose for two days. He brings Keeper Marethari over to speak with the Warden.
Later, after Marethari asks you to search for Tamlen, Fenarel asks to come along. The Keeper will approve if asked, otherwise you can simply lie to Merrill to let him come.
Dragon Age II
Fenarel appears at the Dalish camp at Sundermount. If Hawke and Merrill complete the New Path quest and thus kill Marethari, they will be confronted by him and a group of other hunters when they leave the cave. If Hawke admits that the Keeper was killed by blood magic, they will be allowed to take Merrill away from Sundermount. If Hawke tries to explain that Marethari was possessed, Fenarel and the other hunters will attack, and later, so will every Dalish in the area.
