Yeah I know it's a really short chapter but explains a lot. i will hopefully post the next chapter either later today or tomorrow.

"Doctor, I think it's time we had a proper chat."

"Master" said the Doctor once he was out of the room

"are you upset, Doctor, are you angry? I would be but then I'm me"

"How did you escape the time war?" asked the Doctor

"oh Doctor straight to the point. Don't you want a little chat first?"

"No, I want to know now! You were gone, dying, taken with Rassilon, back to the Dark Days, of the time war. How can you be here?"

"I had some contacts from when I was Harold Saxon. An acquaintance of mine, Jim Moriarty, helped set me up when I first arrived on earth, I crated a rather strong bond with him"

"What?"

"Oh don't you remember Doctor? I could survive even when I was dead. I had a rather nice body when we were on Traken, don't you remember?"

"But that means…" the Doctor whispered, horrified "You took over Moriarty?"

"I floated through space, after the war, after you! A featureless bunch of particles, bonded by the simple need to survive. I honed in on him, on his mind, so similar to mine. He didn't like that very much!" the Master gave a snort of laughter. "He managed to expel me, something no other human has ever been able to do. So I took up residence in the form of his most loyal man, Sebastian Moran. And of course, me, being me, he looks like me now!"

"Wait, that means that you aren't a time lord anymore! That's why you are helping the Axons! Being in the time loop, they would have soaked up so much time energy, they give it to you and you will get a whole new set of regenerations!"

"And for Moriarty too. Everyone gets a reward!"

"Master please, listen to me. I can take you somewhere else please."

"No, Doctor. Do you know why? Because this whole stinking planet needs to be wiped off the face of the universe. . It's contaminated. And you and my trigger will help me to do that. I don't know how Jim got it into Sherlock, but then he is amazingly devious. Are you sure he is safe?"

"they're destroying your Axonite, as we speak"

"oh Doctor have you learned nothing? You can't make an omelette without breaking a few eggs"

the Doctor's eyes widened. A shout came from the main lab.

"Doctor!"

"Run Doctor!" laughed the Master "run for your life!"

For those that don't know, Traken is a place from classic who, a planet on which the Master took over a humans body, rather like he has taken over Sebastian Moran.
