A/N: Due to annoyance with the numbering systems i've changed this chapter from Preface to Chapter 00.

Chapter 00: Madness

I knew that the wizarding world would come to an end. But I didn't think that it would come to an end by my hand.

I have fought for survival my whole life… I had thought, naïvely, that with Voldemort's death I could actually live my life – even if only for a short time. But the Death Eaters survived past the Final Battle.

I only fought the political battle after the death of Voldemort – ensuring that the Death Eaters were arrested and thrown in jail with as fair a trial as I could manage. However, the large majority of the wizarding world still lived within their prejudices, and I couldn't stop them all.

In the end the Death Eaters went after the last of my friends and their children to stop my defiance. I lost Neville, Ron, George, Molly, Arthur, Bill, Charlie, Andromeda and Hermione in the first wave of attacks where they targeted all my friends simultaneously. Luna, the four Weasley children and Teddy (my Godson) were the only once to survive since I had realised something was planned when there was an unprovoked attack on me. I had to make the choice on who to save, and I did what I knew they would have wanted – I saved the children.

I started the real fight then. Protecting what was left of my family and actively fighting the new threat with the mundane-born and magical beings by my side.

But the wizarding world crumpled. The non-magicals found out about us and the world fell into a war. At first, I was able to maintain relative peace since a lot of the beings listened to me and the mundane born (as they preferred to be known) had an intrinsic understanding of how the non-magical world thought and so they either helped or hid. And with the support of the Crown, there was relative piece. After three years, magical beings across the world were given their treaties of peace and in some cases (such as the vampires, werewolves, goblins, dwarves and veela) they were given complete independence and land to call their own. The wizards and witches weren't so lucky.

The Purebloods started attacking the mundanes, and there was no longer anything I could do for them, beyond ensuring that the mundanes didn't take their hatred out on the innocent children (particularly the half-blood and mundane-borns) or the magical beings. The children, who the werewolves and Veela's allowed me to shield and protect in their lands, and in some cases mundane-born adults who have sworn to peace were also given sanctuary to help look after the children. Parents of these children, either moved with them or gave them up while they fought for understanding and peace.

However, the wizards wouldn't give in, and I held almost no power in the other countries – particularly Russia were the supremacy was as bad (or worse) then in Britain. And so, the attacks and destruction continued.

On her dying breath Luna told me of a way. A way to wipe out every last wizard and witch on the plant – saving the mundanes from themselves before they could go nuclear. Before I enacted the ritual, I tried to change it enough that it wouldn't kill the children or the innocent, but I had no way of knowing if it worked. So, I went forward with the guilt on my mind as though I had killed them all because I couldn't prove otherwise.

There were 2,637,706,132 children on planet earth at the time.

872,904 of them were magical.

I committed genocide to save the mundanes.

However, the ritual I used combined with my status meant that I couldn't die as well. A sacrifice was required. That sacrifice was my continued existence and inability to forget.

I saved all 2,635,960,324 mundane children.

I saved all 4,937,239,321 mundane adults.

But I will never forget the deaths of the 872,904 innocent children, which I (probably) caused.

Deaths that I would cause again, if it meant saving the rest of my planet. It was a hard choice.

An impossible choice.

I chose to kill my people so that the mundanes may survive.

Everyone thought that London was a common place, full of common people, living common lives. They were wrong. You leave behind a world full of wonder and magic and step into one with a Mad Man.

If you want a quiet life with tea and crumpets, then living a life with me is not the way to go. I would also suggest staying away from Mad Men, especially one's with a Blue Box.

My incredible luck meant that I met the maddest of all Mad Men; who reached out one ordinary day, took my hand, and said "run."

So much for beans on toast; but this man, this Mad Man and his bigger on the inside Blue Box, is one of the best things that has ever happened to me. He's unusual, yes, but caring and amazing. He made me live my new life instead of just survive it.

I will never regret running that night.
