Darth Siegg, born Kotor Hil, was a Human male. He was born in Theed at the height of the Clone Wars. He never knew his father, a Jedi who was fighting when he was born, so he and his mother were very close. At the climax of the war, his father was killed by the Clone soldiers under his command during Order 66. A year later, the 501st Legion and Darth Vader attacked Naboo. Kotor's mother was killed in the fighting and Kotor was taken as a prisoner to Vader. Vader sensed the boy's power and took him back to the Imperial Palace. Palpatine approved of training the boy as a Dark Jedi and ordered Vader to teach the boy in person.
