The Entity

The Entity was a Sith Spirit enslaved by Darth Baras, who helped facilitate his rise to power and ascendancy onto the Dark Council with her powers of precognition and farseeing. The Entity hated her enslavement, and seeked freedom from her fate. Centuries ago, she nearly brought the galaxy to its knees and eradicated the Jedi Order, and considers being used as a political tool an insult to these past deeds.

Behind the Scenes
It is unknown, who the Entity was in life, but based on implications, it is most likely Kreia.
