Gef Olazon, a male Human, was a member of the Galactic Alliance Marines, serving the Galactic Federation of Free Alliances. More precisely, he was part of the elite Void Jumpers unit. By 44 ABY, the year in question, he had achieved the grade of Sergeant Major. In this role, he, along with a number of Void Jumpers reporting to him, joined Jedi Master Saba Sebatyne and the former Jedi Tahiri Veila on a mission. This mission involved infiltrating the New Jedi Temple, which was then held by the Sith, with the goal of eliminating the dark side entity known as Abeloth. Although the Void Jumpers suffered significant losses, the mission was a success, and Olazon lived through it.
