The details of the Ashcroft Experiments have never been released, the implications of which were considered 'not in the public good'.
Nevertheless, rumor and superstitions abound. According to common accounts, researchers at the University of Bath, England, had been performing trials of a recently developed mind exchange rifle, attempting to determine more efficient beam configurations. Professor Ashcroft led the experiments, taking it in turns to trade bodies with an assistant and back again.
Testing occurred over several days. However, on the last day, building work rendered the test chamber unusable. In need of a large, open but deserted space in which to conclude their experiments, the scientists moved to a former chapel on the University grounds. The chapel, now derelict, was said to have once been the abode of the so-called Baby-Eating Nun of the 16th Century, a rather macabre tale.
Whatever occurred during this final test, screams -both those of men and something thoroughly unhuman- were heard across the campus. Three men were rushed to hospital with grievous bite wounds. As for Professor Ashcroft, he was confined to a mental asylum where he remains to this day, utterly insane.
All footage was supposedly destroyed, though forgeries surface now and again online. The event might have gone unnoticed by the wider world had it not been for the software patch released shortly after which limited the proton beam of the swap rifle to within a far tighter range of frequencies, as well as guidance advising customers to avoid using the device in burial grounds, churches, or places of great tragedy.
