History
On Earth-689 the Black Knight was defeated and imprisoned by the Avengers. The Avengers had been tricked by the Scarlet Centurion into imprisoning all of the super heroes and villains. The Centurion offered them knowledge of the future so that the group might conquer famine, plague, and pestilence and bring about a golden era of peace. Black Knight was presumably released when the Avengers were defeated by their Earth-616 counterparts.[1]
