Celestial War (Earth-888)

The Celestial War was an cosmic event that began at the early existence of the universe, invoked by the First Firmament againts its multi-colored Celestials.

Origins
The war began with an cosmic being known as the First Firmament, who created the Celestial servants out of lonilness. There were two "factions": the Aspirants who seeked its approval, and the Celestials who made creation and wanted their creations to evoled. Sacriledge it saw, and began the war against the Celestials, commanding the Aspirants to wipe them out.

Conflict
The war began, and the Aspirants and the Celestial rebels fought in a heated combat across the infinite expansion of the known universe and beyond. Both side killed each other evently, their strength equal to themselves as the war raged on. The Aspirants, finding this pointless as they're evenly matched, created the Godkiller Armor and was proven to be a powerful instrument of destruction, to which had the Celestials to fall back. However, an internel conflict arises for the Aspirants, to which they stripped the Godkiller Armour for parts when a civil war began. This allowed for the Celestials to recover and destroy their Aspirant counterparts.

Due to the actions of the Aspirants, the stripping of the Armour, and its internal conflict, the Celestials was able tod defeat them, and shatter the First Firmament, which its fragments formed the Infinity Stones. The First Firmament to which remained unshattered fled outside of the universe, along with the surviving Aspirants.

Aftermath
When the First Firmament was shattered, and its fragments formed the Infinity Stones, its departure from the universe allowed for the Celestials release the Abstract Entities from the Chains of Heaven. This event allowed the Celestials to perform their duty as cosmic judges and experiment on life in their liking, performances of evolution on their town. The Abstract Entities would also be allowed to stablized the universe and perform their specific functions in maintenance of the universe.
