The Yularen family represented a powerful lineage of Humans that existed towards the end of the Galactic Republic during its final years. Among its prominent figures were Thull Yularen, who served as an educator at the Anaxes Citadel, and Wullf Yularen, a Republic admiral who later became part of the Galactic Empire. Located on the planet of Anaxes, the family owned an estate. Somehow, the Yularen family came to possess the Letter from Christophsis, a correspondence between [Ahsoka Tano](/article/ahsoka_tano/legends], then a Jedi Apprentice, and Tallisibeth Enwandung-Esterhazy that contained a direct recounting of the battle. The circumstances of how they obtained this letter remain unknown.
