These legendary offspring of the Emperor are both immortal and infertile. Not all of his ancestors are Sensei, and it is theorized that they are only those born with genetic structure similar to his. They are immortal in terms of aging, and though they typically have amazing powers of recovery, they can be killed. They have the ability to channel pure Warp energy, untainted by the hate, disease, or anger of the Chaos powers. They radiate confidence and harmony. Since they cannot feel or channel any of the emotions of Chaos, they are invisible to the Ruinous Powers and safe from their predation. The Imperium often views them as heretics owing to their psychic abilities. Some are influenced by the Illuminati to take part in the Long Watch, preparing for the last battle against Chaos. A very few choose to use their abilities for Chaos, becoming Grey Sensei.
