This article contains spoilers for Doctor Who: Origins #2.
Genesis of the Daleks, where they sent the Doctor back to ancient Skaro in an attempt to prevent the creation of the Daleks.
The Doctor chose to spare the Daleks, clinging on to hope that even the evil of the Daleks would ultimately lead to something good. Tragically, his optimism was proven to be naivete; the Time Lords had correctly predicted a day when the Daleks would threaten even Gallifrey, and all creation wound up caught in a cataclysmic Time War. Gallifrey vanished, banished to another dimension by the Doctor, and - as seen in Doctor Who season 11 - it was ultimately destroyed by the Master.
Doctor Who: Origins #2, by Jodie Ho, Roberta Ingranata, and Warnia K. Sahadewa, reveals the Time Lords may not be gone after all. Solicits have suggested the comic will finally explain why Jo Martin's forgotten Doctor became a fugitive from her own race, and the second issue sees her brought face-to-face with a secret the Time Lords have hidden from the galaxy. She visits a Time Lord colony on the planet Kreb, where the Doctor learns another secret of Time Lord regeneration; that Time Lord regenerations serve to accelerate evolution, with each incarnation evolving to suit the environment they are in. This means every Time Lord colony will swiftly evolve in a different direction, essentially becoming a separate species.
It's quite rare to see a Time Lord colony, and indeed it's quite possible the Time Lords practiced eugenics; Doctor Who: Origins kicked off with the Doctor given a mission to destroy Kreb and all its inhabitants, after all, so the Time Lords may well have been horrified to learn their species would evolve in this way. Still, there's no reason every generation of Time Lords felt the same way, and the Time Lords could have easily used this tactic to ensure some of their race survived the Time War. The Doctor Who, albeit in a very different form.
This does not, however, mean that the Doctor's relationship with the Time Lords would be the same. Recent seasons have revealed the Doctor is not a Time Lord at all; she is actually the Timeless Child, a being from another universe who became the base genetic code for the entire Time Lord race. The Timeless Child retcon introduces an intriguing new degree of distance between future Doctors and the Time Lords, setting them up to be potential enemies as Doctor Who continues.
Doctor Who: Origins #2 is available now from Titan Comics.
