Gallifrey: Beginning of Bad Wolf

Thousand Year War

So to stop them Bad Wolf added life to the planet of Skaro. Two species, the Kaleds and the Thals. But her plan failed, the Kaled and the Thals began a neutronic war on eachother. Burning and killing all of the things Bad Wolf gave them. The war became know as the Thousand Year War. Even as the cause of the war was lost to memory, both sides remained committed to victory and the Kaleds achieved a scientific breakthrough when Davros engineered the Daleks. When the Dalek were created all of their emotions were extracted from them, all but hate and anger. The Daleks believed that they were the supreme beings, due to not having their judgement clouded by emotions, wants, or needs. They soon attacked the Kaleds and Thals, the Daleks decide to release radiation from their nuclear reactors into Skaro's atmosphere, leaving only the Daleks alive. They had killed them swiftly and without a second thought as they were lesser beings than the almighty Daleks. The only non-Dalek left alive was Davros their creator. The Daleks moved on to attack the first creatures, the first beings, the Time Lords themselves beginning the Time War.
