Dark Fantasy Anime Underground Library Background

Create a masterpiece, breathtaking ultra-detailed dark fantasy anime interior background in a polished Genshin Impact-inspired style. Scene and environment: A hidden underground library built into a forgotten crypt, with stone arches, shadowy alcoves, and endless ancient bookshelves disappearing into darkness. Background elements: Floating candles illuminate long reading tables, piles of forbidden tomes and chained books rest on cracked stone desks, magical symbols glow faintly on the floor, and skull motifs are carved into the pillars. Broken statues, sealed doors, and iron gates add mystery. Atmosphere and lighting: Low violet-blue arcane glow mixed with flickering candlelight. Dust motes, magical particles, and rolling ground fog create a secretive and eerie atmosphere. Composition and style: No people, no characters, no text. Background only. Dense environmental storytelling, luxurious dark magic atmosphere, polished anime fantasy rendering, vertical 9:16.
