The gillmen are a mysterious race who live beneath the waters. They lurk in hopes of attacking swimmers, fishermen, and small ships. Evidence suggests they are attracted to humanoid women in white.
Gillmen, also known as Reavers in the Demiplane of Dread, are tall humanoid creatures covered with scales, averaging 7 feet in height. They have large, fish-like eyes and webbed hands and feet. Their fingers end in short but deadly sharp claws that can rip through flesh and tissue with ease. Their mouths are wide and filled with rows of needle-like teeth. They live in schools, but sometimes an individual is exiled. These outcasts leave the salty sea water behind and find a fresh water lake, lagoon, or river in which to live.
Gillmen speak with a lisping, hissing language that is very difficult for other creatures to match. Many of the sounds they use to communicate are ultrasonic, so men cannot even hear them. No gillman has ever been known to speak a human tongue.
A gillman's lair is often hidden beneath a coral reef or at the heart of a thick forest of seaweed. They feed on the raw flesh of their victims. They prefer land dwelling creatures and sea mammals. The gillman is not noted for clever tactics and strategies. As a rule, it is a savage opponent that tears his enemies into pieces.
