Jelpax

The Fifth Doctor had a dream. In it he was in his first incarnation back on Gallifrey. In the dream there was a Time Lord named Jelpax. Jelpax was at the Time Lord Academy with the Doctor, and was a member of the group known as the Deca. He also had a fascination with the Dark Times while at the Academy. (PROSE: Divided Loyalties)

Unlike many of the others in the group, Jelpax did not become a Renegade Time Lord. Instead, he remained on Gallifrey and became one of the major recorders, keeping an eye on matters in four or five minor galaxies. It was his team that foresaw a future in which the Daleks conquered the universe and sent the Doctor back to avert their creation.

He later became a coordinator of the APC Net. He was a staunch supporter of Lord Cardinal, later Lord President Borusa, his former teacher. Borusa was only made aware of the many artefacts from the Dark Times, such as the Ring of Rassilon and the Black Scrolls of Rassilon from Jelpax. Borusa later used this knowledge to seek immortality in the Death Zone. (TV: The Five Doctors) Realising his connection to Borusa's betrayal, Jelpax was removed from his posting and ended up on monitoring duty. (PROSE: Divided Loyalties)
