This is the first message to be left from the Master to the discoverer of the plans of the rebellion.
Recently I have been sucked into the Time War due to events following a battle with the Doctor, I during that time discovered that the drumbeat in my head (and as a result all the actions I committed under its influence) was implanted artificially into my brain by Rassilon the president of Gallifrey and leader of the time lord race, in order to complete the final sanction a motive which was intended to end the universe itself. After I killed Rassilon I went on the run after hours of wandering I came across a small group of people whom not knowing of what the doctor was up to were plotting a secret rebellion, it was then that I realised why I was there and what I was to do. I was the Master and these would be my people.
I told the people what the doctor was planning to do and though they agreed that it was the only way they claimed that they wished to live so I created a plan, using a chameleon arc we would escape the war the same way that I had before only this time everyone would be hidden on 21st century earth until somebody gets this message and finds them all.
So please I ask you humble human find them and bring my people back please, please please.
I'll reveal who's watching this in chapter 2
