About twenty years before the beginning of the game Azelle's father, Victor raped a maid in the service of his wife Cigyun and from that assalt came Azelle. Cigyun fled after and upon learning that she had entered a relationship with Prince Kurth Azelle's father killed himself leaving Azelle to be cared for by his half-brother Arvis.

Worried about the cleric Edain, Azelle, along with his close friend Lex, both joined Sigurd's army in the events of the prologue chapter. He is also childhood friends with the Thunder Mage Tailtiu.

Azelle's fate after the Battle of Belhalla is unknown, with certain rumors suggesting that he is taken into custody by Arvis, and others suggesting that he succumbs to an unnamed illness. This is most likely credited to Arvis's words to Sigurd, "Azelle may be a half-brother of mine, but he means the world to me." Shouzou Kaga originally intended for Azelle to appear in the second generation, where it is discovered that he has been turned into a statue, alongside the other survivors from the Battle of Belhalla.
