Prologue

Harry Potter age 136 looked over the ruins that once was Hogwarts castle and was having a bitter taste in his he won the war but it was all for nothing, every one of his friends died in the war and after Voldemort finally went down a new disease killed most of the magic population. This disease was set free because the final battle between Voldemort and Harry blew up a great portion of the Department of Mysteries where the virus was developed to use against enemies of the dark lord. Once set free it went out of control and killed 90% of all magical live.

He walked down to the rubble looking for the place where he would make his runic circle, this runic circle would take him back to July 31, 1991.

After weeks of calculations and research he would go back in time to do it all over again, to make sure that this time he would defeat Voldemort without losing everything he hold dear.

Finding the right spot what used to be the middle of the great hall he took out a silver knife and cut his finger open. With his bloodied finger he began drawing the desired runes with his own blood on the floor.

2 hours later Harry was done and sat right in the middle of the circle and began powering up the circle with his magic. Runes began glowing gold one after an other while Harry was starting to sweat under the strain to keep the magic flowing into the runes.

When all the runes were glowing gold Harry took out his wand and pressed the tip off it to his scar while uttering the last 2 words of this life to make the passage through time. "Avada Kedavra''

After a green flash Harry fell dead in the middle of the runic circle that started to glow a fierce red as soon as Harry's soul came free of his body. With a great surge of power the runes exploded in white and send Harry's soul back to 1991, when the light went down the runes disappeared and the body of the boy-who-lived and the defeater of you-know-who lay dead in the middle of the great all with a smile on his face.

A/N: well it's the start for the first story I will write so I know it isn't the best work you have seen but I'll do my best.
