Tytonus, a Sith Lord of Human descent and female, lived during the time of the Great Galactic War. Prior to 3643 BBY, she seceded from the Sith Empire and established her own kingdom on Begeren, an ancient world sacred to the Sith. During the period known as the Cold War, she formed an alliance with Grathan, a rebellious Sith Lord situated on Dromund Kaas; however, this alliance ultimately led to her downfall when she was persuaded to spearhead an attack against Kaas City.
