Around 60 BBY, Kurlin Vos held the position of sheyf for both Kiffu and Kiffex. Tinté Vos was his sibling.
Despite Tinté's strong opposition, Kurlin permitted Tholme, the Jedi Watchman stationed on Kiffu, to begin training the young Quinlan Vos in the ways of the Jedi.
Following the passing of Quinlan's mother and father, Tinté manipulated Quinlan into using his psychometric abilities to re-experience their final moments, with the intention of corrupting him towards the dark side of the Force. This act infuriated Kurlin, leading him to authorize Tholme to bring Quinlan to Coruscant for his Jedi training, instead of allowing him to stay on Kiffu.
As a consequence, Tinté laced Kurlin's beverage with poison. With her brother now deceased, she commenced her extended rule as sheyf.
