Demonic Muse

It's a summer night, the air is surprisingly cold, there is nothing else but the sound of crickets in the night sky.
This story begins in a cold basement, lit only by a single candle, 4 teenage boys stand in a circle holding hands, a symbol drawn onto the cold basement floor.
They chant a spell, over and over and over again.
Until one of the boys opens his eyes and says a single sentence:

''Dark one from way below, rise above and let yourself show!''
The boys slowly open their eyes one by one looking at each other and around the room.

''Dark one from below, rise above and let yourself show!''

The candle suddenly sparks, and dark smoke emerges from the symbol on the ground.
The boys step back looking in disbelief as a pitch-black large claw shoots up from the ground.
Another claw emerges as a large broad demonic beast slowly pulls itself up from the darkness.
A thundering laughter blows out the candle, suddenly the boys are in pitch darkness surrounded by something demonic...

This is my first story ever!
Please excuse any grammar mistakes, English is not my native language.
This is a adult themed book, foul language, gore, sex drugs and rock 'n roll!
Join our boys and their demonic muse in their way to fame, dark magic, music and mystery.

I hope you enjoy!! Thank you!!
