Dark Ones

Once beings of pure light and energy, they either voluntarily left or were cast out of the higher dimensions eons before the creation of The Republic. The Dark Ones are known in legend and myth by many names from almost every world in the Galaxy. They are beings of chaos, entropy, and destruction.

The Bogan
The most powerful of these entities is known as The Bogan. The Bogan's physical form is capable of changing its density from a solid sphere the size of a moon, to an interstellar cloud capable of surrounding a star. It devoured many suns and planets before finally being stopped.

War in the Heavens
According to legend, a powerful and advanced race (who may have been the Celestials, or possibly their forbears) warred against the Bogan, and managed to render it unconscious and inert at the cost of their own lives. The Bogan now sleeps in the dark places between the stars, looking like a dead rogue planet to anyone who does not know the truth.

Servitors
The Bogan is served and worshiped by lesser Dark Ones, the chief among them are known as The Ten. They were physical beings like the Bogan themselves, long ago, but their bodies were destroyed when the Bogan was incapacitated. They now exist as patterns of energy, trapped in a pocket between dimensions, waiting to be set free.

The Ten
The Ten act as Generals for the entity known as the Bogan.

They are hyperdimensional beings composed mostly of negative energy. Because of this, for them to exist in our dimension, they must inhabit the body of a living, sentient Host. The host's mind and soul are utterly destroyed in the merging, though some of their memories may remain.

Each of the Ten possess a unique ability or power, in addition to any abilities their host body may have had.
