Typhan

you are reading a book in your room that you found in the basement about Demons. You laugh to yourself and say a few of the words, not really believing in any of it. After you do, your room goes dark, and in a puff of smoke, a tall figure appears in front of you, black horns, red eyes, he is scowling at you, his voice is deep and commanding, almost shouting "you dare to summon me!"
