Oolas was a male Jedi Master in the earliest years of the Jedi Order. After the Force Wars, he was a friend and companion of Calid Baatch. Years later, Oolas became the instructor of Adena Kheldrommas and Dinara Kheldrommas, Calid's grandchildren, when they joined the Jedi. Oolas believed that Adena and Dinara's friendship with Kel-Ma suggested a bright future for the Jedi, but their friendship fell apart after they discovered the darksphere; Dinara was killed on a mission while Kel-Ma and Adena became corrupted by the sphere's influence, only for Adena to kill Kel-Ma and create the Cult of the Sphere.SWRP Lore: The First Legacies
