Prologue:

Wizards were all over the world and most normal people like us had no idea about them. They were right under our noses and yet we could not smell them. It made my wife and I crazy. Finally, the last time our nephew, one of them left, he yelled at us for being what we are. We can't help it, we hate abnormalities. People like us should not have to live in the dark about them. Why, I even remember my nephew telling me about a godfather he has that is charged with murder and a convict. People like that with those capabilities should be persecuted, for the good of the world. My wife, my son (he is twenty) and I decided to take action. We visited churches, town meetings and published ads in newspapers in seven different countries (England, America, Spain, France, China, Portugal and Scotland). We told them a meeting would be held on our street, Privet Drive, in two weeks to discuss these people and their abnormality and how we would handle them.
When the date came, we discussed the abnormal. At least one hundred people from each of the countries we published ads in came. Everyone came to the same conclusion, these people must be wiped out. The people left, preaching our cause. A scientist had asked me how we distinguish those people from normal ones like ourselves. I was uncertain. The scientist resolved he would make something so we would be able to distinguish them from us. After three months research he was able to create a powder that would make a mark on the left upper thigh of a witch/wizard. One our follower was a pilot for a plane that skydivers jump off of. Using his plane we managed to spread this powder all over England. Other countries used their own methods to spread the formula. More and more people found out about our mission.
Meetings were held and eventually leaders of these groups from the countries all met and we discussed how to get rid of these people. Armies were built up, we raised money and bought weapons both legally and illegally. We would go to any measure to get these people. Eventually we began our persecution. Even I was dubious as to who would win this battle, unnatural powers against mechanical devices. Who could predict the result? Apparently the gun is quicker than the wand. We killed scores and scores of these people. Nobody could stop us, we were invincible. We called ourselves the Abattres. We annihilated their race, the worthless, good-for-nothing people they are. The war between the races is over, but I do believe that there are many still out there. Our secret police, with our son as the commander, still persecute them and make sure they are no longer. I do wonder at times if my nephew was killed, we kept no records of the dead, only on our side. I suppose he is dead, how could he possibly escape? One thing that concerns me and anyone else who knows is that we never found my nephew's school, Hogwarts I believe the name was.
