Delirium is the immediate sensation of shock and panic in humans which follows seeing a Garou in their Crinos form, or seeing a Garou change forms. Delirium frequently causes a flight response in humans, who will later begin to rationalize and forget what they've seen.


The Delirium has its roots in the Impurgium, the dark time in human and Garou history where Garou literally hunted and culled mankind to keep the other race in check. The horrors inflicted on men were so great in that age that some speculate the Delirium is simply a racial memory and primitive, hind-brain response to confronting one of humankind's oldest 'predators'.
