Existence AC

Existence AC is one of the few existences protected from Ankhseram (The Nothing) by an existential barrier created by the Primordial Arc. It is suggested that it is also the origin of the Primordial herself, as it serves as the location of the Arcane Realm.

Timeline
For simplicity, years will not be included in the gaps between various events until the Music of Everything.

Creation - In the beginning, there was nothing but the Primordial Arc, and an empty universe. She would create many concepts, such as Space, Time, and Life, giving them personifications of her liking. They would represent everything in the existence and the first galaxies were created.

Barrier - After noticing the slow decay of the existence, the Primordial would use half of her powers in order to create a barrier to stop the nothing from entering Existence AC.

Chaos - The Primordial would take part of her deitic energy and give it to a new entity named Alastor. He would become the representation of Chaos in Existence AC.

End of the Primeval Era - After many disagreements between the two powerful entities, the Primordial would eventually force Alastor out of the Primeval Palace (A precursor of the Primal Realm, where the Primordial and many lesser gods would exist), exiling him, and attempting to take away his control of the Existence. Because of this, Alastor would inevitably attack the Primordial and weaken the barrier. She decided to split herself into nine different arcane energies (which would result in the 10 Arc Categories today, including Chaos) in order to temporarily seal Alastor away and protect the existence's barrier from being destroyed.

The First Arcs - The nine arcane energies created by the Primordial would eventually form into separate entities, known as the Arcs. Existence AC would enter a peaceful transition from the Primeval Era to the new Arcs as they continued to expand on galaxies and realities within the universe. Usurpers were created to rule over the galaxies under control of the Arcs.
