A first-person vista shot from the protagonist's eye level, leaning over a lone stone ritual table at the center of a vast, dark iron throne hall at midnight. In the foreground, the protagonist's hands are visible, gripping a black demonic sigil-blade to inscribe a heavy, leather-bound book of prophecy resting on the stone surface. Standing beside the table is an original priestess with long silver hair tied in a high ponytail, curling ram-like horns on her temples, pointed ears, and sharp pale eyes; she wears a white priestess tabard over a pale-blue dress and holds a long ceremonial staff, her expression solemn as she watches the inscription. The hall is cavernous and oppressive, flanked by violet floating brazier-flames that cast an eerie glow, while a massive black iron throne looms in the distant shadows, where only two glowing crimson eyes are visible in the dark. The visual style is that of high-quality anime visual novel key art, featuring high contrast, a dark color palette dominated by blacks and violets, and a mysterious, ominous atmosphere with soft ambient light and floating embers.
