Biography
She was very young when the War began. Her homestead was attacked by the Daleks, she survived by hiding whilst her family were exterminated. She spent the next several years as a Dalek-hunter with other survivors of the occupation on Moldox.

When she was a young woman, Cinder encountered the War Doctor, who had crashed on Moldox in his TARDIS. She helped him infiltrate a Dalek base and uncover their plans to create a Demat weapon that could wipe Gallifrey from history. The Doctor took Cinder in his TARDIS to Gallifrey to warn the Time Lords of the Dalek's plan.

On Gallifrey, Cinder met Rassion and the High Council of Time Lords, but was told to keep quiet as they spoke. After the meeting was over, Cinder was kidnapped by Karlax and the Castellan and was mind probed to back up the Doctor's claims. (PROSE: Engines of War)
