Biography
Layfon and Leerin's foster father from the orphanage in Grendan. He taught Layfon the Psyharden techniques throughout Layfon's childhood. He and Leerin left the orphanage after taking Layfon's side during the gambling incident in Grendan. Derek gave Leerin a box which contains a DITE to recognize Layfon for learning all of the Psyharden techniques. He and Haia's master were brother apprentices. Leerin revealed that he had forgiven Layfon a long time ago. In the novel, he stated Layfon needed forgiveness especially toward himself because he was sober and dull. He also revealed he had a katana ready for Layfon but he finished teaching him the Psyharden skills when he was very young and lost the chance to give it to him afterward since he used a sword. He knew Layfon refused to inherit it because he felt guilty about his wrongdoing and betraying.
