Nestor Drake was born on the planet Mandalore, the son of the Sith Felishia Wilst and Mandalorian Rui Drake. The child's father, Rui, did not know that Felishia was pregnant, and was unaware he had a son until a year after the child's birth. Because of the Rui's mandalorian nomad way of life, conquering and fighting along side of the sith, Rui and Felishia were deployed on separate parts of the system. The child was given the name Nestor by his adoptive grandfather, Darth Sinistrous after the death of his mother in combat. Darth Sinistrous a Transdoshan sith and Felishia's former master, immidiatly was aware that the child was force sensitive.
So trained Nestor in the ways of the sith, always reminding him that the jedi murdered his mother. At age 16 Nestor completed passed his trials and his training was complete. There was nothing more Darth Sinistrous could teach him, it was up to the young sith to begin his self teaching. So he ventured out to learn what the galaxy had to offer.
For six years venture through the core worlds seeking the knowledge of the force until he arrived in the Cocytus system. In the planet of Judecca he discovered a group of Dark Jedi that would offer much knowledge when it comes to learning about the force.
