Alpheus also known as the World Forger, is the very first son of Perpetua, the supposed "Super Celestial" who created an earlier form of the Multiverse. He, along with his brethren The Monitor, Anti-Monitor were tasked with specific roles entitled to each other. The World Forger resided in The World Forge and would observe over creation, that will exist in the future. For many eons, he hammered universes out of the derived terror and hopes of every single being, within the Multiverse. This allowed him to use the stable worlds that rose into the "Orrery of Worlds" and save the remaining unstable worlds for his creation known as Barbatos, to afflict havoc upon.
It wasn't long until Barbatos, to eventually rebel against the World Forger and in doing so, kill him. Following the invasion of the Dark Multiverse, the World Forger managed to reform himself in the "Sixth Dimension".
