Lord Mi'ihen is an ancient character from the Final Fantasy X saga. He was the founder of the Crusaders (originally called the Crimson Blades), and was branded as a traitor to Yevon by the church government. He walked down what would eventually become known as the Mi'ihen Highroad to Bevelle to stand trial.
He was able to convince the clergy that he was doing good, and Yevon brought the Crimson Blades under clergy control. It was during this time that the Yevon clergy decided to change the Crimson Blades to the Crusaders therefore signifying their new-found control over the massive group.
