Dela'core Falligus

"You have trespassed and dishonored our ancestors by your cowardly actions, and now I will show you what it means to be a warrior"

- Phase before engaging the Cybros at Iyo

Dela'core Falligus, known commonly as Phase is a legendary military commander of the Gemini Empire whom had fought in the Gemini Wars and then chose to lead the Corvana Combine forces in the resulting civil wars that shattered Reteran space into three quadrants. He became Grand Executor of the Combine following this and spent centuries honing his combat skills including those that followed him - creating undoubtedly the strongest force in Cerberus at its zenith.

Before the outbreak of the Cerberus Conflict, the Combine was aware of the Federation but had chosen not to get involved out of fear that any breach could enable the Cybros to reappear after millenium. That all changed when the Cybros Sovereignty launched a full-scale Invasion from darkspace and caught the Combine off-guard whom was rightly abandoned by the Gemini and Epsilon factions, Phase was fighting a losing war and kept retreating avoiding an all-out fight with the brute firepower that the Cybros brought with them.

The Cerberus Galactic Conflict became wholesome when the Federation, once thought beneath the Reterans sent relief forces in the shape of Harrison Thompson and the First Fleet and took part in the Battle of Corvana where Federal Marines fought alongside Combine Warriors against an overwhelming Cybros assault. This was the beginning of the Combine-Federation efforts to push the Cybros to Iyo, where the actual invasion fleet would arrive and forced Phase to retreat again to Corvana only to make his heroic last-stand to give time for his acolytes to flee to unknown space.

It is unknown if he survived the encounter with LEGION.

Early Life
Dela'core Falligus wasn't a natural born Reteran, instead was a genetic mutant where the scientists of the Gemini Empire sought ways to create an altered-subspecies but primarily to serve as warriors for the intergalactic Empire. Dela'core was the first and only subject to have survived the incubation and his genome stabilized, leaving him much stronger and physically built but also had made him incapable of natural reproduction. He was an outcast, but earned his place in Reteran society by feat of strength and intelligence even having a hand in developing proto-phase technologies that were field tested in the years before the Gemini Wars

Quotes
"Corvana shall never fall so long as we draw breath, and you would do well to remember that. Now take up your swords, your weapons, your shields and your honor and take to the battlefield! None shall desecrate Corvana!"
