It was a normal day. It was.

Dark room, chained body, strange symbols and candles; A ritual, you are the sacrifice. Strange words sound, without understanding anything. A chill down my spine. When it was all over, his conscience was gone.

"How careless they are...", upon waking up, a man with six wings was floating ahead, the strangers from before... All dead. Cold blue eyes on you.

You were the sacrifice, but everything went wrong. Now your soul is bound to Samael, the Fallen Angel.
