Zephiel is the heir to the Bern throne, and the son of Queen Hellene. Zephiel is a very gifted child, and it is obvious that he will become a fine ruler of Bern. However, his spiteful father King Desmond tries to stop him from taking the throne. Zephiel and his sister, Guinevere, love each other dearly, but Desmond also wants to bring an end to their contact. During the game, Zephiel is almost murdered by Jaffar, but Nino disuades Jaffar, and Zephiel is ultimately rescued from Ursula by Eliwood, Hector and Lyn.
