Tilden Kaah was a male Keshiri individual. He resided on the planet of Kesh following the conclusion of the Great Hyperspace War. He was employed as a personal aide to Seelah Korsin. Seelah Korsin was a member of a group of Sith who had crash-landed on Kesh and subsequently assumed control of the planet after their arrival in 5000 BBY. However, Kaah was secretly an operative for a Keshiri resistance organization. This organization was dedicated to the overthrow of the Sith government. Kaah was a respected intellectual who concealed this fact by pretending to be a superstitious simpleton. This allowed him to avoid raising the suspicions of Seelah and her husband, the Sith leader Yaru Korsin.
Kaah leveraged his position overseeing Seelah's daily schedule to monitor her movements and provide intelligence to the resistance leadership. In 4985 BBY, Kaah informed his superiors about the purge that eliminated numerous members of the Sith species. This purge occurred after the deaths of thousands of Keshiri. The deaths were caused by the poisoning of several water sources by Ravilan Wroth, a trusted advisor to Yaru Korsin. Following this event, Kaah continued his work with the Keshiri resistance until the group's downfall in 4975 BBY.
Tilden Kaah, a male Keshiri, hailed from the planet Kesh. In 5000 BBY, a group of Sith crash-landed on Kesh and declared themselves to be the Keshiri gods, known as the Skyborn. The Keshiri people accepted this claim without question, and the Sith assumed control of the planet. By 4985 BBY, Tilden Kaah was serving as the attendant to Seelah Korsin, the wife of the Sith leader Yaru Korsin. To facilitate his work as a secret agent for a Keshiri resistance group, Kaah, a learned individual, concealed his true intelligence from Korsin. Kaah was constantly at Korsin's side, managing her daily affairs. He found himself physically drawn to Korsin, who maintained excellent physical condition despite her age. She was aware of his attraction but did not reciprocate it. Despite his scholarly background, Kaah presented himself as a superstitious simpleton to Korsin, preventing her from suspecting him. His role was invaluable to the resistance, as he provided inside information about the activities of the Sith rulers of Kesh.
Around 4,985 BBY, Yaru Korsin began spending considerable time with Adari Vaal, the individual who had initially discovered the Sith fifteen years prior and a covert leader of the Keshiri resistance. Seelah tasked Kaah with spying on them. Kaah would follow them during their walks and periodically report his findings back to Seelah. In that year, the population of the city Tetsubal mysteriously died under peculiar circumstances. The sole survivor was Ravilan Wroth, a trusted advisor to Yaru Korsin, who had been visiting various towns in the region. Seelah Korsin concluded that Wroth was responsible for the mysterious plague that devastated Tetsubal and several other settlements. He had accomplished this by poisoning the local water supplies with cyanogen silicate. To convince Yaru Korsin of her findings, Seelah requested that a nervous Kaah bring him a container of the chemical. As a result of this incident, Ravilan Wroth, along with the remaining members of the Sith species who had survived the crash in 5,000 BBY, were wiped out. Following this purge, Kaah informed Adari Vaal and other high-ranking members of the resistance of the news. Kaah continued his work for the resistance for the next decade, until the Keshiri resistance collapsed in 4975 BBY.
Tilden Kaah possessed a cunning nature, enabling him to effectively conceal his involvement with the Keshiri resistance from individuals like the Korsins. Despite his intelligence and scholarly background, he skillfully played the role of a fool, emphasizing a superstitious belief in the Sith's divinity. He was a capable spy, not only monitoring Seelah Korsin's activities for the resistance but also observing the interactions between Yaru Korsin and Adari Vaal at Seelah's request. However, despite working against her, he harbored a strong attraction to Seelah. He often admired her in the mornings as she showered, forgetting that she could sense his presence through the Force. Kaah had purple skin and white hair.
Tilden Kaah made his first appearance in John Jackson Miller's 2009 eBook, Lost Tribe of the Sith: Paragon.
