Yfra functioned as the personal ambassador for the Hapan matriarch, Ta'a Chume, who was female, during the year 23 ABY.
Back in 23 ABY, the Hapan matriarch, Ta'a Chume, employed Yfra as her own personal ambassador. During that year, Tenel Ka, the princess of Hapes, was studying at Luke Skywalker's Jedi Praxeum on Yavin 4. Because Ta'a Chume was Tenel Ka's grandmother, she tasked Yfra with observing Tenel Ka at her place of learning. Tenel Ka was not happy with the idea of Yfra coming to visit her at the Praxeum, both because she thought little of those in her grandmother's court, and because she wanted to keep her status as heir to the throne of the Hapes Consortium a secret. Skywalker became aware of this, and tried to assist the young princess in preventing Yfra's visit to the Jedi academy. When Jacen and Jaina Solo, Tenel Ka's friends and fellow Jedi trainees, were abducted and taken to the Shadow Academy, the clandestine training facility of the Second Imperium, Tenel Ka accompanied Skywalker to rescue them, thereby avoiding Yfra's visit.
After a calamitous lightsaber training session with Jacen resulted in the severing of Tenel Ka's left arm, Yfra escorted the young heir back to Hapes. It was at this time that Yfra made an attempt on the lives of Ta'a Chume, Tenel Ka, and her Jedi classmates while they were staying at Reef Fortress. Yfra orchestrated the sabotage of their wavespeeder, arranged for an ambush by a patch of carnivorous seaweed, and hired a group of lethal Bartokk mercenaries to attack.
Tenel Ka and her companions, using their developing Jedi abilities, successfully thwarted Yfra's scheme. Ultimately, Yfra was taken into custody.
Yfra's initial appearance was in Young Jedi Knights: Shadow Academy, a young-adult novel published in 1995 by Kevin J. Anderson and Rebecca Moesta. She then reappeared in the 1996 novel Young Jedi Knights: Lightsabers, part of the same series and written by the same authors. She also received a mention in Jedi Eclipse, the second novel in the The New Jedi Order duology titled Agents of Chaos, which was released in 2000 and written by James Luceno. Later, in 2008, a profile of Yfra was included in The Complete Star Wars Encyclopedia, a reference book authored by Stephen J. Sansweet and Pablo Hidalgo.
