The Time Lords foresaw a time when the Daleks have destroyed all other life forms and become the dominant creature in the universe. The Doctor was sent to Skaro in a time before the Daleks evolved to avert their creation or affect their genetic development so they evolved into less aggressive creatures, but opted to only delay their development. (DW: "Genesis of the Daleks")
During the 46th century, the Supreme Dalek ordered the duplication of the Doctor and his companions Tegan Jovanka and Vislor Turlough in a plot to assassinate the members of the High Council of the Time Lords on Gallifrey, but the plot was averted. (DW: "Resurrection of the Daleks")
The Gelth, who lost their physical form and became gaseous during the Time War, described the conflict thusly: "The whole universe convulsed. The Time War raged, invisible to smaller species but devastating to higher forms." (DW: "The Unquiet Dead")
According to a legend known to the Sontaran Empire, the Doctor led the battle in the Last Great Time War. The Sontarans were disappointed that they were not allowed to take part in the conflict, which Staal the Undefeated considered to be the "finest war in history." (DW: "The Sontaran Stratagem")
Davros was thought destroyed in the first year of the Time War when his command ship flew into the jaws of the Nightmare Child at the Gates of Elysium. Although the Doctor had failed in his attempt to save him, Davros was rescued when Dalek Caan, a member of the Cult of Skaro who had departed from a point after the Time War's resolution, used an emergency temporal shift to overcome the timelock and return to the war. (DW: "The Stolen Earth") The Doctor fought on the frontline during the Time War and was present during the fall of Arcadia. (DW: "Doomsday")
The Time Lords resurrected the Master because they knew he would be the perfect warrior for a Time War. He escaped in fear after he saw the Dalek Emperor take control of the Cruciform. He made sure they would never find him by using a chameleon arch to turn himself into a human and subsequently hiding at the end of the universe. (DW: "Utopia", "The Sound of Drums")
Eve's species, a time-sensitive race, were not involved in the war but they were attacked by the Daleks because of their ability to read the timelines. Many of their people were exterminated. (SJA: "The Mad Woman in the Attic")
