Ego the Living Planet

Within the Black Galaxy, one mass developed differently from the others. Evolving over millions of years, it grew to the size of a planet and developed intelligence and consciousness along with the ability to move its planet-sized mass by its own will. This planet became known as "Ego, the Living Planet". In its evolution, Ego developed organ-like masses under its surface, one of which is similar to a brain. As all sentient beings, Ego began to plan what its role in the universe would be.
