Evlyn Tabory was the offspring of Rosemari Pressor Tabory, the sibling's daughter of Jorad Pressor, and the descendant of Dillian Pressor.
Around 12 ABY, Evlyn's birth occurred on the Outbound Flight Colony. She supported her uncle in his responsibilities as Guardian of the People by utilizing her abilities with the Force to influence trespassers into succumbing to snares positioned around the Dreadnaughts. Evlyn possessed sensitivity to Force, a truth that Rosemari and Jorad concealed to avert her banishment to D-Three. Despite her desire to accept Luke Skywalker's invitation to receive instruction at the Jedi Praxeum, she chose to accompany her mother and Dean Jinzler to reside within the Empire of the Hand following the retrieval of the Survivors from The Redoubt.
Evlyn's initial introduction took place within Timothy Zahn's Outbound Flight novel, released in 2006.
