Black rot

Black rot was a disease that consumed the infected's brain but left their bodies completely intact.

Effects
The disease was said to cause insomnia and fatigue followed by high fever, sweating, delusions, and ultimately death.

History
In 1372 DR, the necromancer Daxiong who was working on improvements to the process of zombification, followed a case of strange plague to the hamlet of Gillian's Hill. There he was experimenting on recently perished farmers. During that period of time, there were also rumors of a black rot outbreak in the farmlands further south.
