Aidan Bok
Tash Arranda once came into contact with the ghost of this Jedi Knight, after opening the tome The History of the Jedi Knights on the abandoned space station of Nespis VIII. Bok had been charged with guarding the ancient Jedi library on the station shortly before the advent of Emperor Palpatine's New Order. When Palpatine ordered the extermination of the Jedi, Bok was powerless to defeat the Sith lord. He was ashamed of his failure, and remained on the station as a disembodied spirit, trapped in the book, unwilling to become one with the Force. When he helped Tash Arranda escape from the space station and Borborygmus Gog, he reconciled his shame and allowed himself to become immersed in the Force.
