Charlotte LeStrange is a former Chesuncook witch cult member with magically disorienting eyes. Her new job at The Miskatonic University puts her in the Occult Science wing, running errands for mutated faculty and patrolling its stranger corners. Charlotte is enthusiastic about the monsters and cosmic horrors she encounters daily — they are, to her, fascinating. But beneath the disfigured professors and the cheerfully terrifying Dunwichers who wander the halls, something much larger is happening, and Charlotte is the only one who can unravel it.
