The Master Returns
After the Timelord's plot was fouled by The Doctor and The Master. We find ourselves with The Master on trial for his crimes.
"You have been charged with treason!" said Rassilon with disgust, as he stands before The Master and the court. The citadel of the Timelords is shot by a blue laser from a Dalek gun. Shattering the already battered glass dome surrounding the citadel.
The Timelords in the court go into a mass panic running to their battle stations out of the room. Leaving The Master alone in the court trapped there in restraints, which were injecting him with some blue liquid. Which was most likely healing him from his experience on Earth.
Daleks storm Gallifrey killing anyone insight. Eventually breaking into the citadel which is now completely destroyed. The dome shattered and fell leaving it exposed. The Master had wiggled room in his left hand restraint to free it and rip out the other restraints along with syringes. The Master was making his escape when he ran into a Dalek. He runs to the TARDIS storage room and escaped into orbit around the planet. Only to see The Doctor end the Time War he managed to leave the timelock by contecting himself to the heart of the type 45 TARDIS that he stole and vowing vengeance against his destroyed homeplanet.
