Void

In the beginning, there was simply a vast expanse of Ether and Ichor.

Eventually, enough Ichor bonded to form the first complex lifeform - Yuuwu Juriin / Abaddon. Yuuwu Juriin / Abaddon assimilated nearly all Ichor in the Void, eventually becoming the nigh-omnipotent God of chaos and Free magic. Yuuwu Juriin / Abaddon ruled over the Void for millennia, using Free magic to permanently integrate his consciousness into the very concept of chaos.

What little Ichor remained outside Yuuwu Juriin / Abaddon's purview eventually formed into Gurang Zhi / Solane and Huran Zhi / Nyxal. Yuuwu Juriin / Abaddon felt great pleasure in tormenting the two Lesser Gods, lording his great power over the two.

At some point Gurang Zhi / Solane and Huran Zhi / Nyxal worked on developing Rune magic, secretly inscribing runes into the very flesh and blood of Yuuwu Juriin / Abaddon. Orderly Rune magic, being the very antithesis to Yuuwu Juriin / Abaddon's chaotic nature, slowly weakened and killed the God.

The portion of Yuuwu Juriin / Abaddon's corpse surrounded by Rune magic became the world Plumamentia - the Ichor within separating and blooming new life - and the portion outside reformed into a new god - Xurhuan Zhi / Elysia.

Now, Plumamentia is bordered by four Pillars - vast behemoths of Rune magic that dictate the fundamental laws of the world.
