Star Wars: Rebellion
Thrackan Sal-Solo is a human male who is the son of Randil Sal and Tiion Solo and the first cousin of Ben Solo. He was born a year after his cousin Ben and the two of them were raised together on the sparsely-inhabited planet Tralus which with its twin Talus formed the Federation of the Double Worlds on the edge of the Corellian system. His father died when he was very young, and his mother was a reclusive, distrustful woman, who surrounded herself with a staff of droid servants. The family was apparently descended from the ancient emperors of Corellia and Tiion Sal-Solo raised her son to think of himself as a gentleman. While his childhood was initially very lonely, at the age of 8 his mother adopted his cousin Ben when Ben’s parents and younger brother went missing.
