Tee-ubo Doole, a Twi'lek scientist (female) worked at ExGal-4 located on Belkadan during 25 ABY. She harbored feelings of envy towards Danni Quee due to the male personnel's focus on her, and she had an affinity for ryll. During an investigation of an approaching storm with Luther De'Ono, Bendodi Ballow-Reese, and Jerem Cadmir, Tee-ubo made the ultimate sacrifice, giving her oxygen supply and her life to Cadmir by taking her own life. This was to avoid being killed by the overwhelming toxic gases released by dweebits that Yomin Carr, a Yuuzhan Vong warrior, had brought to the planet.
