The End Of The War
Disclaimer: The idea is mine, the story is mine. The characters and everything else is borrowed.
It was finally over. Tom Riddle was dead. So was Harry James Potter. So was almost everyone else. All the Weasleys were dead except Molly and Fred. Fred was taking Georges death hard. He wasn't expected to live until the end of the month. No-one would say but they knew Molly would follow. Her family was her life, so without them...
Percy had died much earlier in the war, well as good as dead. He was lying in Azkaban, his soul having been consumed by the Dementors after it was revealed that he and Fudge were Deatheaters. His body had died when Azkaban was destroyed by the Order during the last raid. Voldemort had escaped taking only 17 out of 63 Deatheaters with him. He had also lost 23 during the fight. The side of light called it a tremendous victory.
No-one spoke of the lost Order or Ministry members. Not even Molly. She never spoke again, just cried for her lost son... and husband. No-one even ever knew that Peter Petigrew was among the dead, and Sirius Orion Black was posthumously cleared of all charges. Except the remaining Order members. Including Harry. He knew and that was the day that he began to distrust the Order, and turned fully from the Ministry. As Harry's trust began to die, so did the Wizarding World's only hope.
Each death affected Harry and he began to teach himself more and more of the Dark Arts. Every night he sank further away from everyone who knew him. He became emotionally unreachable. And unstable. Only Voldemort could get a reaction from him during their increasingly frequent curse-scar communications; chats they had during the evenings. Slowly, they began to understand each other. First Harry began to tolerate for their talks. Then anticipate them. In his emotionless state they became a life-line. Voldemort became his life-line.
They spoke of their days. What they had done. Harry, living in Order Headquarters passed information about the Order, not realising what he was doing at first. After a time he began to sympathise with Voldemort. He began to actively help him. One day he left Order HQ and never returned. The Wizarding world was in an uproar. Sobbing and screaming thinking that Harry had been kidnapped. Completely unsuspecting that he was staying in a four-poster bed big enough for 6 Vernon Dursley's to sleep in comfortably. Let alone in the room adjoining Voldemorte's as his most honoured guest, in Deatheater HQ.
The very day after the search for Harry was given up, Harry and Voldemort went into the main chambers and ordered that they not be disturbed. Hours later, the exact time unknown, Harry James Potter was killed, and so was the last shred of humanity that had been named Tom Marvolo Riddle after his Muggle father. Lord Voldemort and his heir The Dark Prince Voltaire (with his hair dark as pitch above emerald eyes,) emerged. Humanity would fall, and the world would tremble in fear at the Demons of their own creation.
