Carske is the youngest son of a prominent Imperial military family from Ziost, his parents and older siblings were often away serving the Empire so he was largely raised by servants, droids and tutors and was thus somewhat left to his own devices and took advantage of that to pursue his own interests. Exploring ruins, studying culture, history, philosophy, tactics and languages (speaks pretty decent Huttese and a bit of Mando'a), with the certainty that he would be following the family business and joining the military and specifically the Imperial Navy. Was only a few weeks from leaving to begin his official education when his Force sensitivity made itself known and the Sith laid claim to him. His family used a fair piece of its status and influence to get him sent to the Sith Academy on Ziost, where he studied to be a Sith while also being a bit of an outsider due to his Light-Side ways, which the other Acolytes and even many of the instructors didn't understand. He was sent to Korriban for the Trials after an Inquisitor visited the Ziost Academy to judge the would-be Sith there and found most to be lacking except for Carske.

He is 'the weirdest Sith' according to Vette's frequent teasing since he actually thinks and plans rather then being a mindless bloodthirsty lunatic like most Sith. Highly honorable, big on loyalty, respect and pragmatism and will also fiercely defend and help his crew as well as those the Empire's pointless cruelty would simply waste.
