Afterwards
Bail Organa greeted the band of Rebels from Thakwaa with open arms, and Ahsoka gladly helped each of them find the place right place for them in the Rebellion. It wasn't long after the Rebels agreed to join the Rebellion, when Ahsoka introduced Cassian to Davits Draven, leading General for the Alliance Intelligence.
While working in Rebel intelligence, Cassian was promoted to the respectable rank of Captain and gained prestige in the Alliance. Before Ahsoka's alleged death on Malachor in the hands of Darth Vader, Ahsoka assigned her codename "Fulcrum" to Cassian as he recruited more to the Rebellion in the Albarrio Sector. Cassian also took the lead in secret missions to gather Imperial intel across the galaxy. One mission in particular to the planet Wecacoe, he found and reprogrammed an Imperial security droid named K-2SO; together, they formed a genuine partnership.
Cassian later took the lead role in finding Jyn Erso, daughter of Galen Erso, designer of the Emperor's super weapon; the Death Star. Together, Cassian, K-2SO, Jyn Erso, and an array of Rebel sympathisers assaulted the Imperial data headquarters on Scaris to recover the design plans of the Death Star and get them to Rebel command. The mission was a success, but sadly at the cost of Cassian Andor's life along with the entire company of Rebels known as: Rogue One. Without Cassian and the Rebels sacrifice however, the entire Rebel Alliance would have been destroyed by the Empire in the Battle of Yavin.
Zallar and Ondar mourned Cassian's death after the raid on Scaris, however they continued to fight the Empire as justice for him and Callan. Ahsoka introduced the pair to Captain Raymus Antilles, on of Bail Organa's most trusted officers. After a successful raid on a supply point in the heavily fortified Imperial base on Sullust, Captain Antilles recognized their skill in explosives and tactical awareness. Ondar demonstrated his knowledge in demolitions by disabling Imperial gun towers, that if he hadn't done so, their escape from Sullust would have been impossible. Zallar showed his tactical skill as he led the Rebel task force through and out of the Imperial stronghold.
Following the raid on Sullust, Captain Antilles assigned Zallar a position in the Alliance Headquarters on Yavin IV, as a tactical operations observer. In the Battle of Yavin, Zallar aided in overlooking Red Squadron's assault on the first Death Star. Zallar also took part in the Battle of Hoth and witnessed the destruction of the second Death Star at the Battle of Endor. When the war was over, Zallar became acquainted with General Lando Calrissian, who offered him a job as head of logistics for Cloud City security. Zallar happily took the job, and made certain the Empire never returned.
Though aged past his prime, in the rise of First Order, Zallar committed to put his handiwork tactics back to work as he joined Resistance. He took part in monitoring and relaying operations to General Leia Organa Solo in the assault on Starkiller base, then later put his skills to use on the bridge of the Raddus in the Resistances retreat from the First Order.
Following the raid on Sullust, Captain Antilles put Ondar in command of a Rebel demolitions task force nicknamed "Boom Squad". Boom Squad took part in several operations concerning the destruction of Imperial factories and liberating individuals forced to work for the Empire. Through his status in Boom Squad, Ondar got the privilege of meeting Sabine Wren, the Rebellions leading expert in demolitions.
Towards the end of the war, Boom Squad worked often with Sabine Wren in covertly getting aboard Star Destroyers to destroy them. The pact became well known in the Imperial Navy, they were even coined as the "Silent Killers". When the war ended, Ondar remained a part of Boom Squad in searching the galaxy for remnants of Imperial factories and facilities, then destroy them in an effort to prevent the Empire from rising again. However, unlike his good friend Zallar, Ondar didn't return to join the Resistance. Instead, he decided to live a quiet life as a farmer on Lothal with his wife and two kids; however, he still keeps in contact with Boom Squad and Sabine Wren.
Shila played a crucial role following the downfall of Hord's Rebellion, in keeping true to her word in finding what remains of Titus's Army. Bail Organa introduced Shila to the highly respected General Jan Dodonna, who agreed to having Shila being his second in command as she helped search the galaxy for the starships Titus accumulated. Thanks to Shila, General Dodonna's fleet continued to grow in strength as more and more of Titus's Army continued to rally to the Rebellion.
Unfortunately, in the Battle of Atollon, Shila was in command of General Dodonna's gunship, the Orion, when the vessel was destroyed by Grand Admiral Thrawn; there were no survivors. However, Shila's legacy and efforts to build up the Rebellion, were never forgotten. Without her help, General Dodonna's fleet wouldn't have amassed such a power that was taken from the Battle of Scaris to the Battle of Endor.
As for Ahsoka, she continued to work under her alias as Fulcrum for Phoenix. She first met Spectre-2 in person when the Twi'lek handed over a Rodian named Tseebo, who was was equipped with an AJ^6 cyborg construct that held in its data banks several Imperial secrets concerning the development of a new TIE fighter on Lothal. Ahsoka got to know Spectre-2's real name, Hera Syndulla. Hera revealed who Spectre's 1 and 6 were too, Jedi Knight Kanan Jarrus and his Apprentice, Ezra Bridger. Ahsoka got to know the entire Phoenix crew after her aid in rescuing Kanan from what would be a certain death on Mustafar. Later, Ezra Bridger who would save her from falling at the hands of Darth Vader, and her former Master, on Malachor.
