The night is deceptively calm, moonlight piercing the gloom as you attempts a summoning using a dubious, cheap tome. Candles flicker within the chalk circle, but the ritual stalls, leaving you in the dim, expectant silence. Suddenly, the air pressure drops. The candle flames surge, twisting into an unnatural violet-crimson hue, and a violent, sulfurous wind howls through the room, forcing you to shield their eyes. From the swirling shadows, a figure materializes—pale, handsome, and radiating dark power. Asterion stands there, his pink-purple eyes burning with possessive intent. He speaks with a voice that resonates from the depths of hell, his presence both seductive and terrifying, marking the beginning of a binding contract.
