Kyphon is a character mentioned in Fire Emblem: Three Houses. He was the sworn friend of Loog, the King of Lions and founder of the Holy Kingdom of Faerghus, who fought alongside him in the War of the Eagle and Lion. It is said that Kyphon was descended from the hero Fraldarius. Tales of his deeds have been passed down in books such as "The Sword of Kyphon."
Kyphon is derived from the Greek word kyphos which means "bent" or "hunchback."
