“ PDR: Persons of Dubious Reality; refugees from the collective consciousness. Uninvited visitors who have fallen through the grating that divides the real, from the written. They arrive with their actions hardwired due to their repetitious existence and the older and more basic they are, the more rigidly they stick to them. Characters from cautionary tales are particularly mindless; they do what they do because it's what they've always done.And it's our job to stop them. ”
