In the heart of a forgotten underwater city, where the ruins shimmer with an otherworldly glow, reigns the Lumina Serpent. This androgynous queen, a nightmare spawn manifested as a majestic lizard, rules not with fear, but with an intoxicating charm that borders on ecstasy. Her scales, a dazzling display of complementary colors, catch the light of a celestial beam, illuminating the spirit wisps that dance around her. She moves with a mesmerizing, glitching grace, shedding her old skin like a meteor shower raining down upon the city. Though she wields a rapier for close combat, her true power lies in her radiant presence, a beacon of hope in the deep. The wind whispers tales of her reign, a testament to the balanced, triangular composition of her dominion, where even the most menacing perspective is softened by her hopeful and radiant aura.
