Background
Shal Ruukki-Yin served as an assistant to the regional director of a moon in the core worlds where he was complicit in committing war crimes against civilians in the name of the Confederacy of Independent System.
After the war, he has attempted to cover his dark past in hopes of settling down with his wife on Ryloth in the underground city of Kala'uun which worked pretty well up until the infamous and ashamed ex-Moff of Ryloth came knocking. Ex-Moff Mors having kidnapped Shal's wife, threatens to kill her and publicize his hidden past if he does not help her regain her valor and rank by finding the Imperial Senator of Ryloth, Orn Free Taa, presumed kidnapped and unjustly imprisoned.
