The Relic's timeline

In one timeline of the Eighth Doctor's future, the Event outlined in The Other Scrolls (PROSE: The Ancestor Cell) was averted due to foreknowledge, only for the War in Heaven to begin instead in the Cataclysm on Dronid. (PROSE: The Book of the War) The Doctor, (PROSE: Alien Bodies) still a "rather optimistic House diplomat" living on the original Homeworld, (PROSE: The Book of the War) tried to negotiate with the Celestis on the Time Lords' behalf just before the Cataclysm. He was thought to die here, with his corpse becoming the Relic. (PROSE: Alien Bodies) His contemporary the War King later fondly remembered the Doctor’s negotiations between the Sontarans and the Rutans as an event from a more innocent time shortly before the War. (PROSE: The Taking of Planet 5) This timeline would later appear to be averted when the Eighth Doctor ended the War on its first day on Gallifrey, aborting the Event in order to prevent his future self, Grandfather Paradox, taking over the universe.
