The Conquering Hermit

The Conquering Hermit was a master swordsman in his prime, who dreamt of honour and peace by ridding the world of all evil. At some point he came into ownership of Reidai Kitetsu, a blade said to be possessed by an evil spirit or demon. He then secluded himself for 50 years and through great personal sacrifice, including the lost of his entire left arm, he mastered it's mysterious powers. Unfortunately, the evil presence of the blade had corrupted his vision, and he returned to the outside-world with plans to bring about world peace by forcing everybody under his rule.
