Sorzus Syn

Sorzus Syn was female Dark Jedi who was exiled from the Jedi Order following the Hundred-Year Darkness. Sorzus Syn and her fellow Dark Jedi enslaved the natives Sith of Korriban, christened themselves the first of the Sith Lords, and instituted a new order that centered around worship and practice of the dark side of the Force.

During her reign, Syn wrote the Book of Sith: Secrets from the Dark Side which was a chronicle of her encounters with Sith Purebloods, explorations in alchemy, and the foundations of the Sith Order.
