Little is known about Darth Ptas. What little we do know has come at great expense. Many Wookiees died in the great wars of Kashyyyk to learn certain things about the past of Darth Ptas. What little we do know is that Darth Ptas was once known as Lady Aku, an apprentice of Darth Ikijji, who in turn was an apprentice of Darth Syn, one of the original members of Dark Lords of the Sith. Before she was Lady Aku, nothing much is known other than that the journals of Darth Knave reveal that he lured her into his Sith Order, Sith Legends, having discovered her on Dantooine.
