Cursed Gothic Cathedral Throne Room

A dark gothic fantasy anime illustration in a vertical composition. At the exact center of a ruined cathedral-like palace, [Riu], a small melancholic boy in black clothing, sits curled forward on an enormous ornate high-backed throne. Towering staircases rise on both left and right, with broken arches and gothic spires in the background. Far above the throne hovers a tiny glowing angelic silhouette with white wings and a halo, while a colossal translucent ghostly face with long dark hair and sad violet eyes gazes down through hanging black threads and chains. In the foreground and midground: a large black cat plush doll in the lower-left, a cracked skull with a crown ornament in the lower-right, a round birdcage to the right of the throne, a balance scale on the left, a chessboard with scattered black and white pieces at the bottom, a heart-shaped ornament hanging at upper-left, a crescent-moon ornament at upper-right, and at least four broken empty picture frames suspended or leaning. The environment is detailed with dangling thin chains, beads, black roses, scattered petals, shattered glass, wet reflective stone puddles, and candles burning with purple flames. Lighting is dramatic and cinematic, featuring a deep [black, violet, indigo, and cold lavender] color palette with glowing candlelight, glittering dust, and deep shadows.
