Cyron Klask (age 19), like Saytriona Cinto, was a Jedi Padawan when Order 66 occurred. His previous Master, Taron Malicos, had already been exiled by the Jedi after he started using the Dark Side. Klask, after witnessing Saytriona being shot by a clone, follows his Master’s footsteps and turns to the Dark Side. Even though he uses the Dark Side, Klask is not a Sith. Being a Dark Side user, Klask is a Dark Jedi. 

Using his anger, he kills many clones, and also a Jedi Knight who tried to stop him. He steals holocrons from the Jedi Temple, mostly ones that have to do with the Dark Side. To get credits to buy a ship, he sells 2 holocrons to Luthen. 

Currently, Klask is on Tatooine after breaking his ship with an outburst of anger. He does not know that Saytriona is alive, and is still out to get revenge for her “death”.
