Tom had been separated from the Obscurus for thirteen years. The entity still swirled about in a protective bubble in a private room in Nurmengard, now the headquarters of the global wizarding empire that he and Grindelwald ruled. Tom was pleased that Grindelwald had not destroyed it. Despite the fact that it had almost killed him at the last, it had still saved his life years ago, and he did not forget that. Like Tom himself, it had deserved to be saved.
