A Force-sensitive Weequay, Yollo was trained in the ways of the Force by the Jedi Order, eventually attaining the rank of Jedi Master. Following the Great Galactic War and the resurgence of the Sith Empire, Master Yollo returned to the ancestral Jedi homeworld Tython with the rest of the Order and helped rebuild during the Cold War, residing at the Temple there. Selecting the young Spanios as his Padawan, Master Yollo and fellow Master Silvarte became suspicious of their students, believing that both Padawans Spanios and Moracen had begun a romantic relationship. To get an idea of the situation's severity, Master Silvarte sent another Padawan to discover whether the two apprentices were indeed romantically involved.
