The Casaya Team was a selection of members of the Rebel Alliance chosen by Mon Mothma and Crix Madine to investigate the mysterious disappearance of Alliance leaders Leia Organa and Han Solo. After a long and eventful search, they located where the pair had been taken and rescued Organa, though Solo had been killed long before. While the team was largely successful, it was not without pain and six of the nine members sustained various degrees of injury. Upon returning to the rebel fleet, now stationed around Sullust, they were nearly disbanded but their leader, Kervis Griggs, convinced rebel command to let them continue on as a special forces unit. Aelynn then joined the team as their medic, a station which it had been previously lacking. The team was sent on several other assignments, one of them being to locate Luke Skywalker, and in that time picked up a new member, Doreen Bark. It also experienced the loss of sniper Redjaw, who seemed to have defected to the Blood Corps, though in reality was working as a double agent for Griggs and Princess Leia. Mercenary/Bodyguard Osk joined forces with the team to fill the gap left by Redjaw.
The second notable mission of Casaya Team was to dismantle the resurgent Blood Corps. This occupied the team for months and was filled with various skirmishes with the Blood Corps and several encounters with Redjaw and a posse he had formed. In the end it was not Casaya Team but Redjaw and Khlorinne Bloed that brought and end to the Blood Corps and it was Redjaw, with help from Osk, who killed Major Blood. Despite its success, the team was now on the brink of collapse as most of its members distrusted Griggs and there were several in Rebel High Command who wished to see the team dispersed. Upon reaching the Rebel base it was evident that the team would not hold together and, after Griggs was promoted to general and became part of High Command, the team was dispersed.
But not all of Casaya Team went their separate ways as Me-Dari Callo hoped to use some of them in a new special forces unit she was commanding and kept in contact with several of the ex-Casayas. When Trasso and Arins divulged information they had learned that Darth Vader was still alive, Callo gathered Trasso, Arins, Bolo, Kyssek, and Fargost to investigate. This led them to Coruscant, where the group briefly lost Fargost, and then to Mustafar where they met with Nioman Dokoora and Teuch Neuko and were reunited with Griggs, who decided that this business was best left in the hands of the "Jedi". Shortly afterwards, Casaya Team, minus Griggs who had been put into custody by Rebel High Command, participated in the Battle of Taldornadi and infiltrated and disabled the Imperial flagship, but not without cost; Fargost and Bolo were both killed in the battle. After the Peace was made with the Empire, Casaya Team served under the new government, the Coalition, reprising its role as a special missions unit with the addition of demolitions expert and supplementary medic Crystel Chabo, co-pilot Nomiyar Took, and sniper Khlorinne Bloed.
Twenty years later, in 28 BBY, they were still working as a special forces unit. Their next assignment was to investigate a group of former Alliance leaders who had broken off and gone into hiding. They crossed paths with rogue sniper and former Blood Corps affiliate Queen, who was on the same job. Things got tense and in their first encounter Queen injured several members of Casaya Team, and in the next she unintentionally killed Chabo in a frenzied nighttime battle on Arebeddon. After this incident the team was called off of that job and ended up flying to Mustafar to aid Jorum Bark in discovering the whereabouts of Force sensitive children that had gone missing. The team, accompanied by Sironne Ostobel, Jorum's wife, was stranded when Vader used the Force to disable their ship. They concocted a desperate plan to destroy Vader and his acolytes, Luke Skywalker and Gareth Holvin, but changed course after all members received a vision by Vader of what would happen if they pursued that course; the result was the death of all members of the team. This hit particularly hard for Khlorinne, who experienced her death by Queen, and eventually led to her selling her sniper rifle and abruptly leaving the team as they recovered on Taldornadi. However, there they picked up two new members: "Savage", a former TIE Fighter pilot demolitions expert, and Julien Bloed, Talon and Leia's teenage son who took a job as the team's tech expert.
The team then returned to Coruscant for some much-needed leave time when a Coalition sniper warned them that they were soon to be taken into custody by General Sheppard. This sniper, who went by Scarlet Fever, had lost her entire team recently and suspected Sheppard was behind it. Casaya Team went rogue, and was soon contacted by Leia for a favor: she wanted them to take Vader, who had left Mustafar and was now on his own, into their hands while the Blood Corps would think him dead. Griggs agreed and the team loaded up an unconscious and heavily damaged Vader for Aelynn to repair. In order to have access to the equipment needed, Vader would have to be taken in secret to Taldornadi so Griggs and Aelynn went there with Leia while Me-Dari Callo took command of the rest of the team.
