Even in the earlier days the priests of darkness have been close to the swamp and many have even experienced what it is to be a denizen of the swamp among others. The curse of slaads is an ancient spell known to worshippers of Burglefloogah which even today amazes many. The curse is a disease that gives birth to slaads and often the one who is inflicted by the disease may either be consumed by the disease or by the slaads she's giving birth to. The disease, while resistant, is curable, but they say that the disease can be contagious as well. The metamorphosis that is caused by the spell requires a sacrifice, a slaad.
