- ―Yas'tua to Rak'k about the sith, after telling Alema Rar he has a working swoop
Yas'tua was a Bothan living on Korriban around 40 ABY. He was a member of the Korriban spaceport's ground crew, and was the taskmaster of Rak'k and a Human. The trio met Alema Rar when she landed at the spaceport, and Rak'k told her the location of the One Sith over Yas'tua's objections. Alema then stole Yas'tua's swoop from him to use as transport to the Valley of the Dark Lords.
