Atlas was starring up at St Mungos, he had been sitting in the dank side alley for at least 3 hours and his legs were starting to protest. Clasped against his chest he had the box that contained the soul of Kate Derum. He had learned of its owner from Logan, who had stated that the soul could simply be released and would eventually find its way back to its owner but he wasn't willing to trust something so important to a man who seemed to have the relative emotional compacity of a teaspoon. He knew what ward and even what room Ms Derum was in but still he hesitated.
What was he supposed to say to her once he had returned it? Would there be medi wizards crawling all about? Unlikely, he had waited until the night shift for his errand but Ms Derum was a rare case and Atlas had no idea if she would be under special watch. Gathering his resolve he stood up, mindful of the worn wooden box, which was generating a remarkable amount of heat. He entered the hospital and made a bee line for the lift, shocked to find that he wasn't stopped. As soon as the doors closed Atlas carefully produced a medics badge from his back pocket. They were actually deplorably easy to reconstruct with some time and minimal effort.
A series of nervous twists and turns brought Atlas to the wing had been looking for. All of the 4th unforgivable victims had all been placed in one ward. He thought maybe he would know Kate Derum on sight somehow, but eventually it was the box that altered him to her. She looked dead, which he supposed she was in a way. He held out the box, running a hand over the top of the wood before opening it. The light was blinding and he stumbled backwards at the sudden power shift in the air all around him. True to what Logan said the soul hung in the air for a moment before zipping down and disapeering into the girl's chest. Atlas stood there dumbly and waited.
