Human-Triumvirate War
Humanity's first encounter with an alien species took the form of a devastating war against the Triumvirate. This faction was a conglomerate of three different species that held technological superiority over the UEG, leading to a mostly one-sided war that almost resulted in Mankind's extinction.
The Conflict
Prelude
In 2520, a series of unexpected attacks left much of the UEG's outer colonies in ruin. Soon, they came to realise that this was the act of a completely alien faction, who sought to exterminate Humanity, whom they saw as a potential threat to their own existence. After a failed attempt at communication that left a diplomatic UDF fleet destroyed, the UEG officially declared war against its alien aggressors. For the years that followed, the Triumvirate proves themselves superior technologically, winning most ground and space battles against Humanity.
Deployment
The conception of Project: PRAETORIAN shortly followed the century-long demonic war, as a way to develop soldiers that would be better capable of facing extreme threats. However, it wasn't until the early 2500's that technology could be sufficiently developed enough to attempt such an experiment.
The selection process targeted children, notably five-six year old children in orphanages that exhibited above average physical traits. The experiment, while brutal, painful and dangerous, was ultimately a success and all 200 candidates became fully trained and augmented super soldiers by the age of 16. When the Triumvirate attacked, the Praetorians were deployed to the most crucial ground engagements in order to maximise their effectivity.
The Engagement
The unfortunate truth was that while the Praetorians could stand toe-to-toe with Triumvirate ground forces, there were too few of them to turn the tables of war. Humanity was ultimately still losing, mostly due to their naval inferiority. Over the years, UEG territory had decreased exponentially and by 2545, almost all colonies were lost. The remaining fleets had been recalled to the innermost worlds that held the utmost importance to Humanity. At the centre of these six worlds was Earth, Humanity’s home world.
Inevitably, the Triumvirate discovered the location of three of these six worlds and despite having a greater number of defences in comparison to the outer colonies, all four fell within the span of a few years. Only three worlds remained now: Chorus II, Outreach and Earth, and UEG officials were desperately developing multiple contingency plans in the event of total loss.
