On the order of Grand Master of the Prydonian Chapter, Rassilon, Lord Griffen and Lady Jodelex await the collapse of the dying star, Qqaba. Fenris, also known as the Hell-Bringer, a mercenary from the future, travels back in time to sabotage the experiment and change Time Lord history. He causes the ships' stasis haloes to fail, leaving Lord Omega doomed to fall into the black hole. However, Rassilon's intervention sees Fenris dispatched and the experiment a success. Fenris' discarded belt provides the much needed technology to use the new energy and will provide a form of directional control.
