This massive creature spends it's time hiding in the darkest of places. It has one giant glowing eye which emits light in a cone in whichever direction it looks. No real adventurer has ever successfully killed one of these creatures. Their entire bodies being obscured in the darkness no one truly knows what it looks like. The hands being revealed in the light of it's eye however have revealed that this monster has teal skin and it's hands at least or human like in shape, making many believe that other than it's eye it is mostly humanoid in shape.
