"''The universe does not abide weakness, and we are it's ambassadors"

- The Overseers

The Cartharsis is an omnipotent hierarchal hegemony of militaristic races all advancing toward universal perfection and domination by systematically exterminating civilizations it deems weak and purifying those it deems strong into it's near unstoppable juggernaut. Hailing from another dimension, the Catharsis have for countless billions of years been infecting all life in its path with a biological virus known as Purity, many universes are now completely lifeless, safe for this alien menace.

Description
The Catharsis is a collection of species that is believed to have existed for billions of years, inhabiting different plains of existence and a vast amount of universes, of which they can completely control. It is believed that they are currently expanding into the universe that contains the First Gigaquadrant, which surely doesn’t bode well for its inhabitants. The Catharsis are masters of space and time, harvesting basically anything they can lay their hands on, such as Dark Energy, which makes up 73% of the mass-energy of the universe.

Early History
It is believed that the first life form in the Catharsis is known as Purity, a sentient virus with the goal of consumption of all sentient life. This Purity Virus became the life-force of the Manipulators and the Purity Aliens, and as their technology grew, so too did their need for more hosts. After tens of thousands of the years, the Manipulators formed the Catharsis, which comes from the term purification, believing that they are doing good by infecting all sentient life in the universe. The Catharsis in their early years were nothing short but a plague, spreading across their native universe consuming all life they came across with Purity until they came to a point when the entire universe was infected.

However, their lust for more hosts demanded that they find more, and the Catharsis began to expand into other universes and dimensions, consuming their natural resources and especially their native life forms. This cycle repeated itself for billions upon billions of years, making the Catharsis immensely old and powerful. As the Catharsis evolved both technologically and biologically, the Purity Virus was over time, improved and ultimately perfected, without a cure.

Recent History
During the Intergalactic War, the bulk of the Cognatus Alliance vanished through a portal on Caprica, however the Thirteenth Tribe redirected this portal to another universe, one infected with the Purity Virus. The Virus quickly and voraciously attacked the Cognatus, infecting them with the virus, with them, the Cognatus ships, technology and species now answered to the will of the Catharsis and the Manipulators. Rumours state that their interest is increasing in this universe, which surely does not bode well...

Relations
The Catharsis rarely see the need for alliances, instead infecting them with the Purity Virus, however sometimes when a civilization they contact have power equal to their own, they will ally with them in order to avoid an unnessacary war. Enemies however, are swiftly and ruthlessly crushed and infected.

Allies
These life-forms will be useful and therefore, infection is not necessary.
