Harry Potter and the Magic of the Shadows
(I don't own any of this save the plot. All cards can be found in Yugioh World Championship Edition 2010, unless otherwise noted.
This is set post-Battle City and during Order of the Phoenix.)
Prologue:
It had been a week since the Dark Mark had burned. The unknown Death Eater had finally made it back to England. He had escaped capture during the first fall of the Dark Lord by simply running. Once the mark burned he knew it was time to return. Slowly, so as to not set off alarms, he returned. It was almost time to return to the Dark Lord. As he walked toward the deserted ally where he could finally apperate the final leg of his journey, he saw a young man with pure white hair.
He grinned. He might as well have some fun before returning. A quick stunner knocked the boy out. Dragging the body into the ally, the Death Eater saw a glint of gold. He reached down to take it.
Anyone who was outside the ally would have seen a blinding flash of gold light. Shortly afterwords they would have heard someone screaming and someone else laughing. And then it was quiet.
Shortly afterwords a young man with white hair walked out of the ally, humming tunelessly as he twirled a small stick between his fingers. "Well, well, well. . . this will be fun. . . "
