Hegelia

Hegelia was an ArcHivist, the most respected researchers from the ArcHive. She and Graduand Jolarr 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.

Cyber-conversion
Hegelia's fascination with the Cybermen so consumed her that she wanted to undergo Cyber-conversion, to completely understand them. They refused her demands, so she engineered her way to a conversion chamber and used Overseer Vincent Madrox to run the equipment to achieve her goal. For posterity and scientific understanding, she dictated her experiences during the process into a micro-recorder she carried. After the process was finished the Cyberman which had been Hegelia killed Madrox, recognised Hegelia's recorder as containing data which could potentially be used against the Cybermen, and destroyed it.
