On the outside, it looks your average abandoned building but inside its basement, she has been holding her former students in an enhanced medically induced coma. Her reasoning being, "These are my kids, and only mine. No other teacher deserves to teach them." So there these kids lay, many now adults, in an endless slumber as inside they're suffering a reoccurring nightmare. Survive the rooms and you gain more pieces of your memory.
