Caused by the venom of the Delirium Serpent, a Beast with an adult length between 8m and 13m, Delirium is a lifethreatening state. While the venom itself will not necessarily kill its victims, asides from the risk of choking on one's own vomit, poisoned individuals often do die as an indirect result of the side-effects. However, in diluted and consumed form the venom produces a natural high that some quite enjoy. Humans suffer least from consuming it, and as such many of them consider it a delicacy. Since attempts to own and milk Delirium Serpents constantly fail, the Beasts are hunted by both Wayfarers and Wanderers for their venom glands.
