Summary: The second war is over Harry and his twin sister, the-twins-who-lived, won, Voldemort was dead. But on the battlefield an unknown spell was fired at them and they were send to a world, where they never existed, Voldemort rules and he has a heir- the son of his first General Lucius Malfoy- Draco Malfoy.
It was over, they had won. Harry stood on the battlefield, bloody, worn out and tired. But they had won, the second war was finally over. Voldemort was dead. He looked around. Before him was Voldemorts dead body, they had destroyed all the horcruxes and were able to kill him. The whole field was littered with dead bodies. Both from the light and from the dark side.
Harry had seen many of his friends and family fall and die. The first victim of the second war had been his friend Cedric. His godfather followed soon. And now so many were dead- his mentor and surrogate grandfather Albus Dumbledore; his old professors and order members Minerva McGonagall, Mad-eye Moody, Filius Flitwick; their spies in Voldemorts ranks, Severus Snape and Draco Malfoy; his friends, Hermione Granger, Neville Longbottom, Luna Lovegood, Remus and Tonks, Ron and his grilfriend Ginny Weasley were all dead he could see their bodies from where he stood were near him and his twin sister, who stood beside him. He didn't know were the others were, but hoped they survived. The surviving were heading to the meeting point, some taking the injured with them.
"It's over now, isn't it?" he turned from observing the battlefield and Bellatrix Lestranges body not far from Voldemorts, she had thrown herself into one of the curses they had thrown onto Voldemorts back.
He didn't get an answer, at least not a spoken one. Because beside him stood a Tigersus, a white tiger with equally white wings.
"Seems like the curse wasn't lifted. But we'll find something for you to be turned into your human form again, sis. Don't worry."
Jamie Lilian Potter had been hit by a curse and locked in her animagus form one year ago. They had hoped she would be able to turn back after Voldemorts death but she wasn't.
"I know, you're strong." he said to her, seemingly having understood what she said. Their twin bond had been really helpful in that last year. They had learned that they were able to talk in their minds so they could have conversations, despite her being in the form of a Tigersus.
Tigersi were really rare animagus forms. It was a magical being, therefore able to use wizards spells and curses and their own power of healing. They were highly intelligent and loyal, but they were also fierce fighters. One wouldn't want a Tigersus as an enemy. They were able to sense the intention of the people around them. The known population were five Tigersi worldwide and then one animagus- Jamie Potter.
While they were talking, both bloody and tired ,something moved in the bodies. The person lying there wasn't already dead, but badly injured. He wore a deatheater mask and lifted his head, looking at the twins,standing alone and unguarded. He smiled under the broken mask , lifted his wand and whispered something.
"There will be no more twins, Master is avenged." and he died with a smile ghosting over his lips.
Meanwhile the twins were hit by a violet stream of light, for a moment they glowed and then they disappeared. The people who saw were shocked.
For some days they searched for them, then the world mourned the-twins-who-lived.
