Lucien spent his entire life searching for immortality, and actually ran into the Red Knight on three separate occasions. The first time, the Red Knight told Lucien that the fight was a waste of his time, and that he would never be good enough. The second time, Lucien barely got away with his life. The third time, he had managed to improve his fighting skills enough to impress the Red Knight and joined the team. Now that he is immortal though, he is bitter at the price he has to pay for it.
