Anime Swamp Dungeon Within a Gothic Castle

An anime-inspired scene of a swamp inside a Gothic castle dungeon. Damp, moss-covered stone walls and arches frame rusty iron bars. Shallow, murky water pools reflect neon-green bioluminescent fungi and flickering lanterns. Thick mist floats over the water; vines creep from cracks; submerged staircases hint at a vast labyrinth. In the distance, ghostly shapes and dragonflies hover among dim torches, blending eerie dungeon atmosphere with lush swamp fantasy. Rendered with bold anime cel-shading, vivid greens, teals, and purples, high-contrast lighting, and crisp outlines.
