He is the most powerful of the lieutenants of Nehant and was imprisoned during the war against Nehant in a cave on the Amethyst Glacier. He took advantage of these years of confinement to strengthen himself. He was released by his son Azaram, who, with the help of Furnace, killed his father's jailer: the ice elf priestess Nibelle. Once free, he hastened to join the mists of the Border where is the stone in which Nehant is locked up. He participated in the destruction of the first 3 chains of the prison: the first with the help of Azaram, Furnace and other demons, the second thanks to a ritual and the third with the help of Ciramor. Despite the disappearance of a part of the spirit of Nehant through the gate of infinity opened by Dragon, Amidaraxar continues to seek a way to break the last chain and free his lord and master. To help him in his task he also ask his son to release Utkin one of the offspring of Nehant. He released the body of Néhant from his stone prison and the latter entrusted him with these powers thus allowing his current body to die. Thanks to these powers the general-in-chief has called a gigantic number of demons to crush the other guilds for the glory of Néhant and thus prepare his return. He programmed with Zejabel and Almaria the battle of Akushin in order to keep the Xziarite army from Meragi and send an army of Naser to shave the capital of Kotoba and assassinate the emperor. When he discovered that Dimizar had taken possession of the body of Nehant, he became furious and tried to confront him, but his magic had no effect on the body of his late master. The corrupter then took control of the heart stone of the general nehantist and at the same time his mind.
