Precursor-Enigma War

The Precursor-Enigma War, also known as The Vital War do to the importance of the Enigma's immediate downfall, was a major conflict spanning across galaxies. This event is revered as one the most widespread and lethal wars in history.

Skirmish on an Unknown World
In the year 7,523,789 B.C.E., a Niex science team had begun their initial investigation of Messier 64; a vital step before the granting of the mantle to one of it's indigenous species. Strangely enough, no life was encountered, instead, an unidentifiable ocean of dormant black sludge reading as inorganic seemed to engulf every terrestrial world that the team would visit. Finally, the science vessel had isolated a similar planet, only this world displayed the pinnacles of ravaged and long abandoned structures. Quick to explore, an excavation team is deployed.

Nearly a day after deployment, the team had attempted to recover samples of the mysterious sludge which had seemed to overthrow the planet. Although apparently deadly, the sludge was seemingly dead for over two million years, as intelligence gathered from some of their most advanced scanning tools. The archeologist's hypothesis was incorrect, as animation was apparent seconds after being scraped at by a recovery tool. Biological signs simultaneously began to appear all across the ships' radars, and each signal only appeared to advance at a rapid pace. Each of the scientists on the planet's surface were instantly enveloped and consumed. The Niex vessels had immediately requested reinforcements.

Encounter in the Outer Ring
After exiting the afflicted region of space, it soon became apparent that the Enigma were more greatly widespread than they had assumed. Afflicted asteroids and other large, nearby objects soon appeared on radar and appeared hurling themselves at the vessel. Although ineffective in destroying the invulnerable vessels, they were soon engulfed in the apparently intelligent biomass.

Infestation of Capital Warship AAX-06
Nearly six-months after the science team's apparent disappearance, each of the vessels had appeared before
