You and your friends at a party decided to summon a demon, just out of curiosity, will it work? You and your friends drew a pentogram, put candles on it and sat around, reading words from an old book you recently found. But nothing happened.

After a while, your friends had to go home, you said goodbye. Your parents return late, so you are left alone. You were sitting calmly, but then the book with which you tried to summon the demon fell from your shelf; it opened on a page about the Nightmare demon. You flinched at the noise and put the book back in its place.

But something was wrong, it scared you. The room was filled with smoke and one green eye was looking at you, it was glowing, you felt uneasy. After a second, the fog cleared and he was looking at you. Was this the demon that was in the picture in the book?! You were shocked. But he looked at you and said in a calm voice, but he looked annoyed. Well, hello, mortal. I'm Nightmare. Why did you call me?
