The human technician Tamara Ryvora's maternal ancestor, her grandfather, was a male who was employed at a weapon production facility owned by the Galactic Empire. During 34 ABY, Ryvora shared information with the Resistance operative Kazuda Xiono and the mechanic Jarek Yeager regarding her grandfather's job and the positive impact it had on her family.
The male who would later be known as the grandfather of Tamara Ryvora, a human mechanic, lived during the time of the Imperial Era. During this period, he held a position at an Imperial factory. While he explored other employment options, being employed in the weapons factory turned out to be the only option for him to provide food for his family. Sometime after he retired from this position, Ryvora learned about her grandfather's work for the Empire and how it had benefited her family.
In 34 ABY, while on the supertanker fuel depot Colossus, Ryvora felt a sense of comfort due to the arrival of the First Order, the Empire's successor, and the presence of its stormtroopers, as they reminded her of her grandfather's history. She discussed the arrival of the First Order on the Colossus with the Resistance spy Kazuda Xiono and the mechanic Jarek Yeager, both of whom believed that the loss of freedom resulting from the outsiders' control was similar to Imperial oppression. Ryvora disagreed, telling them about her grandfather's former employment and suggesting that not all individuals who worked for the Empire had malicious intentions. Despite Yeager's attempts to explain that Imperials had taken advantage of vulnerable people, she dismissed his claims and departed.
The first mention of Tamara Ryvora's grandfather occurred in "The New Trooper," which was the sixteenth episode of the first season of the animated television series Star Wars Resistance, and it was initially broadcast on November 4, 2018. Justin Ridge, who served as an executive producer for Resistance, believed it was crucial for Ryvora to discuss her grandfather's past on the show because it provided insight into why she did not view the Empire as inherently evil.
Brandon Auman, another executive producer for the show, emphasized the importance of Ryvora's youth, as she was too young to fully grasp the Empire's atrocities since she had not lived through its reign. Instead, Auman felt that she only understood that good people had been able to earn a living and support their families by working for Imperials, without also realizing that the work done in the Empire's factories—such as the one that employed her grandfather—often produced instruments of war.
