Eligos

"There are many types of monsters out there. Monsters who cause troubles without showing themselves, monsters who abduct children, monsters who devour dreams, monsters who extinguish light... and then, monsters who tell nothing but lies. Lying monsters are a real nuisance. They are much more cunning than others. They pose as humans, even though they have no understanding of the human heart. They eat, even though they've never experienced hunger. They study, even though they have no interest in knowledge. They seek friendship, even though they do not know how to love. If I were to encounter such monsters, I would likely be eaten by them... because in truth, I am that monster."
