In season 2 of Stranger Things the boys dubbed the main villain – The Mindflayer, some of you may be wondering what this creature is. In Dungeons and Dragons Mindflayers are creatures of pure evil, ones that spend most of their time living deep underground perfecting their psionic powers. Also known in game as Illithads, they have been around since 1975 and are almost Lovecraftian in their design. Illithids have a humanoid body with an octopus-like head. They have four tentacles around a lamprey-like mouth, and require the brains of sentient creatures as part of their diet. An illithid who snares a living creature in all four of its tentacles can extract and devour its living brain. Their eyes are pale white, and they can see perfectly well in both darkness and light. Their sense of hearing is slightly poorer than a human’s; they have difficulty distinguishing between several sounds mixed together, yet they are good at discerning from what direction sounds came from. Their skin is purplish blue to gray-green and covered in mucus, and is very sensitive to sunlight. They loathe sunlight, though it does not actually harm them. As a species they see themselves above all and would gladly enslave anyone who opposed them.
