In all my time hunting horrors, I have never had any luck tracking down and binding Abidun. Always I would come upon some place he has tread, riding the dreams of the unsuspecting until their heart gives out or madness takes them. Sometimes it is both. The only thing I consistently find in his victims that have succumbed to the madness is this rhyme they speak over and over and over until their tongue gives out just before their heart stops.
