Time War (The Warrior's universe)

In the Warrior's universe, the Time War began after the Fourth Doctor carried out his mission to destroy the Daleks at their creation, (AUDIO: Dust Devil) as his actions inadvertently inspired the Unified Skaroan Alliance between Thals, Kaleds and Daleks, who obtained time travel from the time ring he had left behind. (AUDIO: Aftershocks) The mortally-wounded Fourth Doctor was retrieved from Skaro by Narvin who supplied him with an elixir to enable him to regenerate, with the Doctor choosing to become a warrior. In his new incarnation, the Warrior arranged the termination of an aberrant Sixth Doctor, existing due to the millions of timelines created by his interference. (AUDIO: Dust Devil)

An outcome of this Time War was the Skaroan Alliance ruling time, bending the Celestial Intervention Agency to their will, but this timeline was sealed in a Carrisent Particum by the Warrior, guided by the Master, shortly after his regeneration. (AUDIO: Aftershocks)

As the War raged, the Warrior became President of Gallifrey and had to order the Difference Office to terminate Time Lords who attempted to travel back in time to stop their younger selves committing atrocities in the Time War. Working with Romana, the Warrior defended Gallifrey from an invasion by Kraals who were part of the Dalek alliance. (AUDIO: The Difference Office)

The War ultimately ended when the Warrior used the power of the Key to Time to avert the conflict, returning a part of him back to his fourth incarnation who now did not cross the wires in the incubation room on Skaro. (AUDIO: The Key To Key To Time)
