a Jedi Knight from Chad III, she grew up with her family on an ocean ranch, migrating on the Algic Current with the herds of tsaelke. Callista was discovered by the maverick Jedi master Djinn Altis at a late age, and agreed to train with him at his facility on Bespin, and later aboard his personal training ship, the newly-christened Chu'unthor. It was during this training that she first met a fellow Jedi named Geith. When she accepted the assignement to intercept and disable the Eye of Palpatine, she and Geith - who was now her lover - were unable to completely eliminate the threat of the ship. So, Callista decided to stay behind and try to disable the ship while Geith returned to get more help. When Geith was killed during his escape attempt, Callista sacrificed her physical body and left her Force-aura in the ship's automated firing computer. Years later, when Luke Skywalker, Cray Mingla, and Nichos Marr rediscovered the Eye of Palpatine, Callista fired on them, thinking that they were Imperial troops come to recover the ship. Then, Irek activated the ship's remote controls, re-initiatiing its original mission. Callista was unable to determine the causes, but she was able to sense Luke's string Force-presence when he was brought on board. She helped him rescue Cray and Nichos, but refused Luke's attempts to store her consciousness in a computer. However, when Cray decided to stay behind and detonate the ship, she gave Callista her own physical body. Callista escaped the Eye of Palpatine, but she could not longer touch the Force. So, while she loved Luke, she felt that they could not be together forever. The two tried everything they could think of to help her regain her Force sensitivity, but she only succeeded in finding the Dark Side. She vowed that, if the Dark Side was all she could touch, then she wanted nothing to do with the Force. This opened a rift between herself and Luke, which widened with each failure. When the Jedi Academy on Yavin 4 was attacked by Admiral Daala's fleet, Callista took matters into her own hands, and set out to strike a blow against the Empire, even without the abilities of the Force. She commandeered a TIE Bomber and landed on the Knight Hammer, quickly sabotaging the ship's complement of TIE Bombers to detonate their payloads and rip out the Super-class Star Destroyer's engines. She then went to confront Daala, allowing the Dark Side to wash over her as she tried to kill Daala. Daala succeeded in stunning Callista, while the Knight Hammer plunged into the core of Yavin. Callista was not killed when the ship exploded, however. She recovered, and escaped in one of the command-level emergency pods. She fled the New Republic and Luke, setting out to break through the barrier of the Dark Side in order to recover her powers. She felt that she needed to do this herself, and sent a final message to Luke, asking him to understand. Her travels led her to Nam Chorios, where she was drawn into the web of Taselda and Beldorion the Hutt. She tried to learn about the Force from both former Jedi, but was unable to truly regain her power. Taselda enslaved her with the promise of returned strength, using Callista to strike at Beldorion. After escaping the old woman, Callista realized that she was trying too hard to restore her Force sensitivity. She felt that this would lead herto the Dark Side, so she allowed herself to become Beldorion's slave as well. This fear - the fear of falling into the Dark Side completely - was what kept Callista from rejoining Luke. She came to understand the strange relationship between the Force in the Spooks and the Therans, and joined one of their troops in working to keep the drochs from leaving the planet. It was Callista who re-initiated Leia Organa-Solo's lightsber training, while they were spending time in a Theran camp. After the defeat of Dzym and Seti Ashgad, Callista again fled Luke, joining Umolly Darm and Be' as rock ivory hunters until she found her way in the Force.
