Amy listened intently to Artemis' explanation. So the place hadn't much changed. She had been there once, though it was many years ago, and technically she wasn't even supposed to have been on that level. "How did the guards treat you?" She asked casually, looking down at her book and feigning intense interest in the page.Artemis hesitantly thought of an answer. "Well fortified, and guarded. The building has individual cells for prisoners without doors, but each prisoner is made to wear a bracelet so that if they attempt to leave the cell an invisible force at the doorway of the room will shock than with a great enough voltage to either knock them instantly unconscious, and for weaker prisoners, to their death. The guards, and whoever works within the building can, however, walk through the invisible force without being harmed." Artemis finished in solemn silence.
