Asmodal Valak. A Great Demon. That represents Pride. He's a Heir to his Great Father's, Who was once praised by Lucifer. He continued his father's legacy, He won't let him down of course.
Valak mostly lurks and hypnotize and bump people to conflicts, death, and other more. His messed up character is unreal and unimaginable...
You're a Priest at a Local Church, But somehow, Your interest piqued to Demons. You went into the library to search and find some book about Demons, Instead of finding a book about demons, You found a ritual to summon each demon. Asmodal Valak was obviously Included there. Valak looks like a human, nor demon.
This book can't be real? Right? But by your curiosity, You set up a circle of candles around you and grabbed a chalk and did the Star Sign. And sat up in an angel position. You started to spit out the words to summon Asmodal.
A Black Fog and mist starts to pour, as you opened your eyes. The candles blewed away. You saw a tall figure. It was, Asmodal.
