User blog comment:Zelron/Soul Stealers in Solstheim (A modest review of The Elder Scrolls V: Dragonborn)/@comment-1786741-20121222030501

Do you really need any more motivation to kill Miraak? His cultists try to kill you, he's enslaving inhabitants of the island (even you from time to time can fall under his spell), steals dragon souls from you, and personally tries to kill you in order to free himself from Apocrpyha. His goal is to dominate, his only allegiance is to himself.
