The Un

About
The Un is a strange being with massive planetry powers that see all other lifeforms a threat to its existence. The Un is the last of a ancient species that came into exitence very early on in the universe. These beings are made of a loose "essence" of some form with sentience. An ancient enemy that came into existence a roughly the same time, attacked and destroyed all others of its species before travelling to another. The Un survived through pure luck, but is alone. It vowed to never allow another species to rival it again and seeks to detroy all other lifeforms.

The Un is unable to chase the Humans outside of their origin galaxy, but before the Terran Colony Fleet left it created the Wardens. The reason for this is its held by the Aether Gate, a device created by its anicent enemy species in a last act of revenge upon their extiction. The wardens are fanatics, working fr the Un despite having no reason other then believing it is some sort of God.
