The Mistake
Voldemort sat in his study at Riddle Manor waiting for his servant to arrive. He was still angry with his followers. The disaster in the Department of Mystery's left him without not only the prophesy, but several of his top lieutenants had been taken into custody.
For crying out loud, they were beaten by six children. These were supposed to be some of his best men. Six bloody children.
If his plan tonight worked, it wouldn't matter. If everything came together the way he thought it would, he would rule not just Britten but probably most of Europe as well.
There was a knock at the beaten wood door, and he called "come in." In walked two men in black robes and knelt in front of him.
"Master, the time turner that you requested." the left one stated as he offered the small device up.
"You did well, Wormtail, did you get the contraceptive charm for me?"
"Yes master, it is contracepto." the man said.
"Very well, be gone your reward will be waiting when I return."
Both the two men promptly left. Voldemort turned to and began to fiddle with the small device. With a soft "Potter your finished" Voldemort disappeared.
James and Lily Potter both responded to the call. James as an auror was trying to secure the area and interview witnesses, while Lily, who had been shopping, was trying to heal an injured child.
The sceen in Diagon alley was a disaster. Several buildings were damaged and several were injured. It wasn't the first time the Death Eaters had hit the alley. Sceans like this on were all to common a round wizardry Britten now.
The war had been going strong for several years and the Potters were still young. They were wanting to get on with there lives. Unfortunatly they weren't getting their wish.
Neither of them noticed a shadow appear on top of one of the buildings. The sinister man quietly sat waiting for his opportunity. It took him a minute to figure out which healer was Lily Potter. With a cruel smile the man took aim with his wand.
"contracepto" the man murmured. The man watched as the burst of light hit Lily in the back and the man disappeared.
Down below Lily felt something hit her. She was confused and checked her self over. Finding nothing, she returned to her work.
Two nights latter Lily decided to have some fun with her husband. Before they got very far, a small difference accured, James remembered to cast the contraceptive charm. This was important because the one Voldemort had cast on Lily was still their and the charm was it's own countercharm.
The reason for the change was that Voldemort had appeared. The brief disturbance in the timeline had great effect. To bad that Voldemort really didn't understand the full implacations of time travel.
