Sean Dolan was once the squire of the Black Knight. He somehow got ahold of the Ebony Blade and traveled around as a drifter until he decided to help repair the recently destroyed Slorenia. In Slorenia he was decided to draw the blade. As a result the souls of the deceased Slorenians were harvested into the blade turning him into the Bloodwraith. The Bloodwraith seemed unstoppable and could not be destroyed. The Avengers could not defeat him. The Scarlet Witch was able to strengthen his bond to Slorenia not only linking him to the people but to the borders as well, trapping him inside.
