- "You had the privilege of pursuing this fight. My people had no such privilege. The fight came to us. They enslaved us. I watched them shackle us. And beat us. And begin strip-mining our world, pilfering its resources. Our place, our people, all held under the Empire's thumb. Until we found a way to wriggle free."
- ―Tolwar Wartol to Mon Mothma
Tolwar Wartol was once a chemist on his pastoral homeworld of Orish. During the Age of the Empire, the Orishen were enslaved by the Galactic Empire, who strip-mined Orish and drained the planet's surface of its natural nutrients, destroying the pastoral haven. Wartol helped create the chemical weapon that destroyed the Imperial occupation but also poisoned his world from the ground to the atmosphere. After the Empire abandoned the doomed planet and Wartol believed this a triumph.
Following the Battle of Endor, he became his people's senator in the New Republic's Galactic Senate, and used his survivor's spirit as part of his campaign. By 5 ABY, Wartol had become the main political opponent of Chancellor Mon Mothma. He also spied on Senator Leia Organa and her husband Han Solo, using a listening device implanted inside the couple's nanny protocol droid T-2LC ("Elsie"). Using the listening device, Wartol eavesdropped on Chancellor Mothma and Princess Leia's meeting with Temmin Wexley and Sinjir Rath Velus discussing the latter pair's discovery of Imperial forces above Jakku.
Seeking to score political capital against Chancellor Mothma, Senator Wartol broke the news on HoloNet and accused her of keeping secrets and being soft. When Mothma tried to rally the Senate to vote to send military forces to Jakku, Wartol managed to convince five senators Ashmin Ek of Anthan Prime, Rethalow of Frong, Dor Wieedo of Rodia, Grelka Sorka, and Nim Tar into voting against Mothma's bill. Wartol was also in cahoots with the Black Sun and Red Key crime syndicate, who wanted to prolong the Galactic Civil War. Wartol also secretly sent Senate Guards to prevent Temmin and Sinjir from leaving Chandrila to search for Norra Wexley and Jas Emari.
As the New Republic was making preparations to transfer the Senate to the Mid Rim world of Nakadia, Tolwar traveled on his personal yacht with Chancellor Mothma. During the hyperspace journey, Wartol admitted manipulating the five senators into opposing Mothma's bill and spying on Senator Organa. Wartol also boasted that Chancellor Mothma's scheduled second vote on sending military forces to Jakku would be defeated on Nakadia. However, Chancellor Mothma managed to delay the vote by smuggling a pta fruit aboard the yacht. As a result, the Nakadian authorities did not allow them to land until they had completed a thorough biosecurity search of his yacht.
While Wartol was preoccupied, Chancellor Mothma's agents Sinjir, Temmin, Han Solo, Jom Barell, and Conder Kyl managed to convince the five senators to change their votes by rescuing Nim Tar's child and offering to pardon them. After finally landing, both Senator Wartol and Chancellor Mothma addressed the press about the new vote. Due to the efforts of Sinjir and the other agents, Mon Mothma's bill passed and the Senate decided to dispatch the New Republic military to Jakku, setting the stage for the Battle of Jakku.
Seeking revenge, Wartol planted a bomb in Chancellor Mothma's office on Chandrila. While paying a "courtesy visit" to deliver another shipment of pta fruits, Sinjir caught Wartol redhanded. Wartol revealed his blaster and fought with Sinjir. During the struggle, Wartol managed to trigger the bomb. After being subdued by Sinjir, a defiant Wartol admitted responsibility for his actions and dared Sinjir to shoot him with his blaster. However, Sinjir responded that he would be tried for his crimes before attending to the bombing. The conversation was recorded by a tech gauntlet worn by Sinjir's friend Conder. Chancellor Mothma was not in her office but her Adviser Auxi Kray Korbin was killed during the explosion. The disgraced Wartol was subsequently arrested by local security forces.
