Illithids (aka Mind Flayers)
A grey man with the head of some elongated squid commands the goblins forward. Without so much as a word, he orders them into formations far more intricate than what the goblins would be capable of alone. Upon reach the fortified wall of the castle, his milky white eyes pierce through the guards of the front gate and they let the drawbridge begin to lower. Before his minions have swarmed the castle, he wraps two of his long tentacles around your throat and put the other two through your eyes.
Masters of dark manipulation and telepathic abilities, mind flayers are tactical coordinators on the mortal plane. Often leading legions of aberrations and other underground creatures, these beings telepathically control any who they come across, turning them either into slaves or keeping them to consume their brains at a later date. Intelligent, crafty and vain, mind flayers are consumed with the perfection of their thoughts and the domination of others.
OM NOM NOM BRAINS
