 Both the Foundation and its predecessor organizations have relied on memory-affecting agents in order to expunge sensitive data from the minds of unauthorized individuals. Though we have generally classed such agents under the umbrella term amnestics, and less accurately amnesiacs, we have in fact used a wide variety of different agents to accomplish this task. Many of our commonly used amnestics are themselves anomalous, either in origin or mechanism. The fact that amnestics are frequently anomalies themselves effectively renders them thomial class SCPs, recklessly handed out to any MTF, field agent or researcher who wants them. Furthermore, the collection of these amnestics are often either fraught with danger or are otherwise ethically problematic.
