Forged in desperation, united by adversity and resurgent in power, the UCM exists for a single purpose - to wrest mankind's lost strongholds from the clutches of the Scourge. A collection of diverse and remote frontier worlds, the UCM is a restless cultural melting pot, bubbling with a righteous desire for vengeance.One and a half centuries after the Scourge captured Earth and the Cradle Worlds, the UCM has expanded beyond all recognition. The greatest military force in the history of humanity has been assembled; a vast armada recently unleashed against enemies old and new.
The Scourge are foul, neuro-parasitic lifeforms which can utterly dominate an unfortunate host, bending its life to its will. They thrive on the conquest and absorption of other races, their very mode of existence as potent a threat as their formidable battlefield technology. They are the galaxy's ultimate predators.Their breathtaking assimilation of the central planets, including Earth itself, has made them the primary threat to the very existence of mankind. Their methods of killing on the battlefield are abhorrent to witness, but violent death at the hand of their potent plasma weaponry can be as nothing compared to the dread of being taken alive.
The Shaltari are an ancient and highly developed species. Their technology is advanced to a level of sophistication rivalled only by its potency. They have traversed the stars for millennia, learned myriad truths, and have fought countless wars. Through their knowledge, the Shaltari transcend even death itself, and can endure indefinitely, perceiving the ebb and flow of time like no other race.In battle, the Shaltari are fearsome adversaries. Their swiftness is unmatched, their firepower unequalled, their bravery undeniable. The beauty of their constructs bellies their true nature; engines of death, honed to lethal perfection long before humanity learned to throw stones. They are peerless masters of technology.
A tiny portion of humanity turned its back on mankind in the waning days of the last Golden Age. Over one and a half centuries later, the PHR has emerged from the shadows as an unrecognisable civilisation, its people irrevocably changed. They are no longer simple human beings, they are post-humans - cyborgs.A society no more than three billion strong, the PHR is a nation of elites, each individual more than a match for several lesser mortals. With remarkable speed, they have made technological advancements surpassing those of the UCM. Since its fiery birth, the PHR has been guided by the enigmatic White Sphere, a mysterious object of immense power. It is treated by the people of the PHR with a reverence bordering on worship.
The Resistance is a complex, characterful and disparate assortment of human survivors on the Cradle Worlds and Earth itself, currently occupied by the dreaded alien Scourge. The very existence of the Resistance has shaped UCM military planning for its Reconquest, which became a war of liberation rather than simply a war of revenge as soon as they were discovered. Indeed, the Resistance alone are responsible for a reconquest being possible at all, as they were able to activate and maintain foldspace nodes on all but one of the Cradle Worlds, allowing UCM invasion fleets to jump to their locations accurately. Theirs is a tale of loss, grit and determination to survive in the face of insurmountable odds. We have already seen how the Resistance on Eden Prime evolved from a cowering group of shell-shocked survivors into a viable (if fragmented) fighting force. The example of Eden Prime can be considered as a general model for the progression of Resistance societies across all the Cradle Worlds and Earth itself. However, the most noticeable aspect that separates the Resistance from all other combatants is their diversity.
