Fog Giants, through slow and clumsy, are also bloodthirsty, vicious killers. Inhabiting the marshes of Fablehaven, they are primitive creatures who wear tattered, matted furs. Their filthy bodies are smeared with oily muck, and their skin is a sickly bluish-gray color. Their hair and beards are typically long and tangled with slime. Fog giants sense prey by smell and hearing. A fog giant named Burlox gave Coulter some vital information on the location of the hidden artifact in Rise of the Evening Star.
