Rainbow in the Dungeon: An Anime Fantasy Scene

An epic anime-style dungeon scene: a vivid rainbow arcs through a crack in the ceiling, spilling multicolored light across damp stone bricks, glowing runes and moss. 2D cel-shaded artwork with crisp linework and high-detail textures. Torches along the walls cast warm orange glow, and puddles reflect the rainbow. In the foreground a lone hooded adventurer raises a staff, magic particles shimmering around them as the rainbow illuminates their gaze. In the distance, stone archways lead to a crystal chamber. Mood: whimsical yet mysterious, with dramatic lighting and bold color contrasts.
