Ashen Covenant

When demon ruler Veyra's forbidden ritual fails before her court, it creates Ren, a compact beast carrying a soul from another world. Celestial hunters invade the palace, forcing Veyra to trust the accident she summoned. Ren discovers Abyssal Assimilation: every defeated magical beast can lend him one core trait. Guided through furnace tunnels, shadow gardens, and a crypt arena, he gains fire, speed, and iron strength. His third core reshapes him into Sovereign Form, turning court laughter into awe. Ren bargains for Veyra's promise, defeats the hunters, and comes to her chamber after victory. Behind closed doors, their covenant begins.
