Graduand Jolarr was an ArcHivist, a researcher from the ArcHive. He and Hegelia time travelled back to study the aftermath of the Cybermen's occupation of Agora. However, Hegelia altered the coordinates so they arrived during the last year of the occupation. Her fascination with the Cybermen so consumed her that she wanted to undergo Cyber-conversion, to completely understand them. After the Cybermen were defeated by the Bronze Knights, the Sixth Doctor took Jolarr back to the ArcHive in the TARDIS, since the ship they had arrived in had drifted back into the past.
