The Mission to Tatooine represents an operation undertaken by Rianna Saren as part of her quest to locate the Slavemaster known as Kheev.
After discovering on Mustafar the potential location of Zarien Kheev on Tatooine, Rianna Saren journeyed to the desert planet in pursuit. However, upon arriving on Tatooine with Zeeo, they noticed Slave I tailing them. Boba Fett shot down Rianna's craft, resulting in a crash within the Dune Sea; Rianna, however, survived and reached a nearby settlement. There, she observed Fett conversing with Sedriss, a key lieutenant of Kheev. Rianna resolved to confront Sedriss to ascertain Kheev's whereabouts. After fighting her way through the settlement, which was heavily guarded by stormtroopers, she finally encountered Sedriss. Saren triumphed over him and demanded information regarding the Empire's holding location for its enslaved individuals, referred to as "volunteers" "volunteers". Sedriss revealed that it was located beyond the scrap yard and derisively called Rianna the "broken one". Enraged by his comment, she retaliated by firing her blaster at him, resulting in Sedriss's death.
After once more battling her way through the town's streets and the adjacent scrap yard, Rianna finally made it to the Imperial slave camp. From atop one of the buildings, she identified her target–Zarien Kheev, entering the facility under the escort of stormtroopers. Saren and Zeeo shadowed him. They disabled the generator and forged a path to the control tower, but along the way, they were ambushed by Kheev, who unleashed a rancor. By commanding Zeeo to engage the beast, Rianna provoked the rancor, causing it to dislodge stalactites onto its own head. While the rancor was stunned, Zeeo launched another attack. After several strikes, the rancor retreated, along with Kheev, who had been observing the entire confrontation from a nearby balcony. Rianna pressed on with her pursuit, eventually reaching the control tower. However, she was once again ambushed by Kheev. This time, he was accompanied by stormtroopers. Rianna and Zeeo were captured and subsequently transported to the Imperial prison on Despayre.
