Gayem Leksende was a male Human cyborg employed by the Czerka Corporation. His service occurred during the Cold War era, a period of tension between the Galactic Republic and the re-emerging Sith Empire.
The Corporation tasked Gayem in 3643 BBY with preventing the Republic from discovering a concealed facility on Tatooine. Intrigued by the doomsday device within, he disregarded his superiors' warnings to stay away and instead sought to claim it for his own.
However, a Republic strike team dispatched by Agent Fauler of the Republic Strategic Information Service was also in search of the facility. Gayem opted for indirect methods, relying on surrogates to achieve his aims, rather than a direct confrontation. Ultimately, a listening post monitored the strike team as they gathered data to pinpoint the facility's location within the Dune Sea. Instead of immediately heading there, Gayem waited as the strike team battled through swarms of cyberneurotic zombies, infected by a Rakata artifact that contained the mind of the Imprisoned One. After the strike team destroyed the Imprisoned One's pawns and subdued the entity, Gayem revealed himself. He offered a substantial sum of credits in exchange for the device, and promised to revoke the kill order on Kamus Orden. The strike team refused and destroyed the device, enraging Gayem. Gayem and his bodyguard then fought the strike team, but were defeated.
