Elder one

Author of pain
being of the underground
nomad, lurker, great old one
ruler of madness and the unsound
darkness creeps' sinners abound
famine, pest, death - no warning signs
blackened eyes are the light that stares as you die
rotting corpses engulfs the land creating bloodied rivers of misery
the dementor controls the burning void where the dead are free to roam
wraith wanderers, dwellers of sadistic terror,
must heed the command of the knighted one,
scattered remnants of life
bound to the curse of the damned.
