Human-Isu War

"When we were still flesh, and our homes still whole, your kind betrayed us. We who made you, we who gave you life."

- Minerva

The Human-First Civilization War was a catastrophic conflict occurred between the First Civilization and the Humans who had developed an immunity to the controlling Pieces of Eden. Little is known about the details of the war, however the distraction of war prevented both parties from observing the impending danger from the heavens; by the time they did, it was too late.

The war ended abruptly, and with far greater casualties on both sides than either had expected. Working together, both parties recovered from the devastation wrought in the final days of war, and begun preparations to prevent such a catastrophe happening again.

The seeds of war
The First Civilization, small in number but advanced technologically, at some stage found themselves in need of a docile workforce so as to support their world. Rapidly advancing the genetic evolution of already existing species, humanity was born. Initially, each and every member of humanity was born with a chemical neuro-transmitter deep inside their brain, that made them susceptible to the illusions and mind controlling powers of the Pieces of Eden; however over time, inbreeding between humanity and their "gods" caused some to be born without the neuro-transmitter active, or indeed present.

At some point during this time, two humans – named Adam and Eve – escaped from their masters with a Piece of Eden known as The Apple, and so begun a series of events that led to war.

The War and Catastrophe
Though technologically superior to their creations, the First Civilization were heavily out-numbered by the numerically superior humans. Somehow, during this conflict, the Pieces of Eden lost their power over humanity, thus preventing a quick end to hostilities, though it was possible that a natural immunity developed among the humans whose forefathers had interbred with their gods.

Eventually however, disaster struck. War on Earth had prevented the First Civilization from observing the impending dangers from "the heavens" which eventually led to an abrupt, and bloody end to the conflict. Both sides suffered heavy losses, and much of the planet was burnt to cinder. Brought to the edge of extinction, humanity and the First Civilization came to peace, and started working together to rebuild their world.

Aftermath and legacy

Both sides suffered cataclysmic losses during the final days of the war, with both being driven to the very brink of extinction; and whilst the First Civilization were still far more technologically advanced than humanity, not even that could save them from the inevitable. Humanity however, who had been built to survive, were more fortunate, and through sheer numbers promised to return stronger than ever.

Realizing that the disaster that had struck the Earth once already was due to strike again, the First Civilization constructed a number of Temples, which would help prevent the event occurring again. Alongside these Temples, the First Civilization also built the Vault, which would serve as the beginning of the path to the Temples.

Very little evidence of the war, or even the First Civilization survived into recorded history. By the late 12th Century, all knowledge of the First Civilization had been forgotten, although their Pieces of Eden continued to affect the world in a myriad of ways; being seen as religious artifacts, or as a means for a number of miracles. By the early 21st Century however, a number of First Civilization technologies had been re-discovered and reversed engineered by the Knights Templar, to provide the Earth with a number of technological advancements, foremost among them being the Animus.
