The Archmage was born in 914. He entered Prince Malcolm's service around 971, establishing himself as an invaluable ally. He even helped the Prince build Castle Wyvern. Already, however, the Archmage had treachery on his mind. As early as 971, he entered into an alliance with Iago, combining the Archmage's magical knowledge and Iago's cunning for various ends. Also during this time, Demona approached the Archmage and secretly entered into his service as his apprentice, treating her mainly as a servant, with considerable contempt and cruelty.

The Archmage's goal, by 975, was to gather together the Grimorum Arcanorum, the Eye of Odin, and the Phoenix Gate as a means of making himself almost invincible. He already had the Grimorum in his keeping, but still needed to obtain the other two magical artifacts. When Princess Elena brought the Phoenix Gate to Castle Wyvern as her dowry for Prince Malcolm that same year, he attempted to seize it from her, first by sending bandits to ambush her, and then sending Demona to steal it for him. But Xanatos and Fox defeated the bandits, and Demona, instead of giving the Gate to the Archmage, kept it to share with Goliath. The Archmage, convinced that she had lost the Gate, cast her off from his service. In 982, the Magus began to serve as his apprentice.

By 984, the Archmage finally rebelled against Prince Malcolm and tried to depose him, but was defeated and banished. He returned in a vengeful mood, however, and struck Prince Malcolm down with a poisoned blow-dart. Since he still had the Grimorum Arcanorum in his possession, which contained the spell necessary to provide an antidote for the Prince, Hudson, Goliath, and Demona pursued him to his nearby cave to recover the book. In the ensuing battle, the Archmage permanently blinded Hudson in one eye, but lost the Grimorum to Goliath, and while charging at him, stumbled and fell into a chasm, seemingly to his doom.

Before he could strike the bottom of the chasm, the Archmage from the future arrived and brought him to the year 995, to obtain the aid of the Weird Sisters in gaining the Grimorum, Eye of Odin, and Phoenix Gate, then to 1020, to have the Sisters recruit Demona and Macbeth for his cause. At last, he took himself to Avalon in 1995, where the Sisters presented the "original Archmage" with the three magical artifacts. The Archmage donned the Eye of Odin and was transformed into a nearly all-powerful sorcerer, then devoured the Grimorum Arcanorum in order to bring it into Avalon with him, and finally took up the Phoenix Gate. Now transformed into an exact duplicate of his future self, he led the initial attack on the Avalon Clan, hoping to use Avalon as his base for conquering the world. After the first battle, he then went back in time to rescue his former self, thus entering the time loop again.

After seeing his former self depart for the year 984, the Archmage attacked the Avalon Clan again. He almost destroyed it, but fortunately, the full fury of his hatred for Goliath defeated him. Goliath was able to remove the Eye of Odin from his brow, causing him to lose control of the Grimorum's energies inside him, and was destroyed in the ensuing magical conflagration.
