Alton Kastle was a human male journalist who worked as a broadcaster on HoloNet News on the planet Lothal. As a broadcast journalist, he helped spread propaganda for the Galactic Empire, including propaganda about Wookiees and local unemployment rates. The Leonis family sometimes watched news broadcasts by Alton Kastle. While Leo Leonis believed the Imperial line, both Zare Leonis and Tepha Leonis came to learn that Kastle was a stooge who often delivered news that was either carefully manicured truth or entirely fictitious.
Alton Kastle was an Imperial broadcaster who was based on the planet Lothal during the Age of the Empire. In 6 BBY, he reported on the Westhills massacre. Kastle claimed that insurgents had destroyed mining equipment and attacked Imperial surveyors in the Westhills, forcing the Empire to send in troops to restore order. In truth, Imperial forces under Lieutenant Piers Roddance had opened fire on a sit-in demonstration by disaffected farmers who had lost their lands to an Imperial mining project. Zare Leonis and his friend Beck Ollet knew the truth but did not tell his parents, who accepted Kastle's account.
Between 5 BBY and 4 BBY, Kastle served as a newscaster for several Imperial HoloNet News reports including Lothal's new Imperial Registration Program, the suppression of a Wookiee revolt on Kashyyyk, reduced unemployment rates, the Empire's new affordable housing program, and a ban on unauthorized mining. While many Imperial citizens on Lothal like Leo Leonis accepted Kastle's reports, others like Leo's wife Tepha Leonis and son Zare regarded his reports as carefully manicured truths or fabricated propaganda designed to portray the Empire in a positive light.
Fictitious reports delivered by Kastle helped drive Corwi Selgrothe, a onetime colleague of Kastle's, to find the Rebellion and seek out the truth.
After the Spectres rebels Ezra Bridger and Garazeb Orrelios attacked an Imperial Troop Transport and rescued Imperial prisoners including Morad Sumar, Marida Sumar and their Aqualish servant, Kastle issued a spin report claiming that the rebels had attacked innocent workers. Kastle's HoloNet transmission was then hacked by a broadcast from the rogue Senator Gall Trayvis claiming that the Jedi Master Luminara Unduli was being imprisoned on Stygeon Prime. On the fourteenth anniversary of Empire Day, Kastle delivered a news report announcing that the holiday was commemorating Emperor Palpatine's creation of the Empire. His broadcast was hacked by a transmission by Gall Trayvis calling on Lothalians to boycott the annual Empire Day celebrations.
Later, Kastle delivered another news broadcast deriding the Lothal City Capitol Building in Lothal's Capital City as a bygone relic. This was quickly shadowed by a coded transmission from Trayvis instructing the Spectres to meet him at the Old Republic Senate Hall. Unknown to the Specters, Trayvis was an undercover agent provocateur working with the Empire to root out and destroy rebel operatives. The rebels narrowly escaped a trap set by Imperial Security Bureau Agent Kallus and Minister Maketh Tua, who were acting under orders from Governor Arihnda Pryce.
After the Spectres escaped the Imperial trap, Kastle hosted an interview with Trayvis, who publicly rededicated himself to serving the Empire. Trayvis also denounced the Spectres as violent extremists who had appropriated his message and placed a bounty on them. In response, the Spectres devised a plan to hijack the Imperial Communications Center near Jalath to give their side of the story. During the Siege of Lothal, Kastle gave a news report claiming that the Spectres had assassinated Tua. In reality, the Spectres had been trying to help Tua escape and Kallus had bombed her shuttle and framed the rebels.
In 2 BBY, Alton Kastle delivered a news broadcast denouncing the former Senator Mon Mothma for her allegedly treasonous speech condemning Emperor Palpatine's complicity in the Ghorman Massacre. This broadcast was picked up by the Spectres, whose ship Ghost was in deep space. Shortly later, the Spectres, who were now part of Phoenix Cell, helped escort the rogue senator through the Archeon Nebula to the planet Dantooine.
Following the death of Kanan Jarrus in 0 BBY, Alton Kastle issued a propaganda broadcast claiming that the Rebellion's efforts on Lothal was lost with the death of their leadership. He then announced that Governor Pryce had organized a parade to commemorate the Imperial leadership's efforts to defeat the "extremists" and that all citizens were required to attend the parade.
A few months after the Battle of Yavin, Kastle delivered a broadcast reporting on the apparent treason of Imperial Captain Iden Versio, who made disparaging remarks regarding the Death Star and the Galactic Empire as a whole. In reality, Versio's comments were part of a ruse to embed herself into the ranks of a Partisan cell calling themselves the Dreamers.
Alton Kastle was a human male broadcaster who lived during the Age of the Empire. He was known for his impeccable dress and familiar, comforting voice. While Kastle was popular with many pro-Imperial citizens, dissenters like Zare Leonis regarded him as an Imperial stooge who distorted the truth and made up lies. Kastle was a staunch Imperial loyalist and regularly denounced the rebels as criminals and traitors.
Because of his affiliation, Kastle wore a gray-blue variant of the Imperial uniform, complete with black boots, belt, and gloves. However, he wore an Imperial media badge rather than a military rank plaque, had a Holonet News patch under the left shoulder, and carried two code cylinders on the right side of the chest. Alton Kastle was noted for being impeccably dressed.
Alton Kastle's voice first appeared in 2014, in the HoloNet News tie-ins to Star Wars Rebels. Alton Kastle was misidentified as Alston Kastle on two occasions in the young readers novel Servants of the Empire: Edge of the Galaxy that was released in October 2014. He was voiced by Steve Blum, who also voiced the rebel character Garazeb Orrelios.
