It had taken him weeks to find the right spell. Rodolphus had read through volume after volume, threatened people, killed people and gone without sleep in order to get what he was after. It was time spent hidden away from the rest of the Death Eaters and the world at large. It pained him to let the world go on as it did.... Mudbloods and blood traitors happily wandering about tainting everything with their impurity. But he had to consider his priorities. They would get what they deserved in time. And so would he.
Gathering what he needed by late Thursday evening, he didn't want to waste any more time and went about organising everything required for the spell and it's consequences. With everything set, Rodolphus repeated the long incantation from the book he had worked so hard to find and took a step back as a black cloud exploded around him.
Walking over to look out of the window, he knew know he would have to wait impatiently to find what he was looking for. The spell was supposed to cast one particular area in darkness - the area he needed to find the stone, but he wouldn't know which area it was until morning.
