Arkiaz came into being as a demon back when the multiverse was just created, his son, Zezko, was born shortly afterwards. Being trained as a deadly war general since creation, Arkiaz possessed an incredible amount of skill and he quickly made his presence known to every demon in existence. Arkiaz fought in many battles across several Hellish Wars for the then-Demon King, Satan, and won support and loyalty from his allies as well as respect from his enemies. However, Satan eventually grew to fear Arkiaz's power and influence, so he had him captured by the Royal Demons and publicly executed. Satan even went a step further by having Arkiaz's wife murdered as well. But Satan would go on to HATE the day he did this though, since he lost arguably his best damn general AND the support of his people, which forced him to resort to underhanded and sneaky tactics in order to maintain his power without fear of rebellion. But this day also started the chain of events that would eventually end Satan's reign as Demon King.
Arkiaz's son, Zezko, also saw his Father die. This drove Zezko to wanting revenge, so he waited until his moment came, when he would be strong enough. Finally, after growing into an adult demon and locating his Father's trident, Zezko battled and killed Satan with his Father's weapon, avenging Arkiaz and becoming the next Demon King before eventually making himself the Demon God after disposing of all who could oppose his right for the title.

After his death, it was sealed away into the depths of Hell until his son, Zezko, found it and used it to slay Satan before becoming the Demon God himself.
