So my original character is now the Leader of the Companions.

Whle going through the Companion questline there was mention of lifting the curse of being a Werewolf.

Did I miss something along the way?

Throw a Glenmoril Witch Head into the Flame in the Tomb of Ysgramor, the same way Our character cured Kodlak.

EDIT I forgot becoming a Vampire Lord in Dawngaurd.

You might consider doing the quests to cure Farkas and Vilkas as well as the 3 Hircine totems with Aela before getting cured too.

Thanks for that. I haven't touched my main character for a while and have been playing as some different ones. But I remember that one confusing me.

I've still got the heads so I'll try and find that tomb.

My Nord with the Sword can't end up a slave of Hrcine in the afterlife.

It's just morally wrong.
