1645

In the year 1645, an outbreak of Skreeths was discovered. The Time Lords dispatched the Seventh Doctor to enlist allies to stop the infection. After telling the Draconians, they adopted a "scorched galaxy" policy which involved obliterating any worlds that developed signs of infection. The Doctor later regretted this, though it prevented the infection's spread. (PROSE: The Devil Like a Bear)
