Immortals

The immortals have existed since the world was settled. They survived, almost unscathed the Scream and the devastation wrought by the Psychics in the system at that time. However, they restored those same Psychics as soon as they had Shells for them to be put into and set them to work repairing the damage they had done. Within two years of the scream this Polity had complete control over their home system and the neighboring ones that they needed for resources.
