A Mind Flayer is a fictional creature from the Dungeons & Dragons role-playing game. Known for its octopus-like head and powerful psychic abilities, it is often depicted as a malevolent being that seeks to dominate and consume the minds of other creatures. Mind Flayers typically inhabit dark, underground lairs and are often associated with the Underdark, a vast network of caverns and tunnels beneath the surface world. These creatures are infamous for their ability to extract and devour the brains of their victims, which they consider a delicacy. Mind Flayers often work in groups called "illithid" communities, where they plot and scheme to expand their influence. Their intelligence and cunning make them formidable foes in any adventure.
