Ancient, mystical Arcanum architecture, grandiose, intricately carved stone walls, ornate Gothic spires, stained glass windows, majestic entrance with heavy iron doors, mysterious lanterns hanging from ceilings, dimly lit corridors, ancient tomes and scrolls scattered on wooden shelves, magical orbs glowing softly, eerie mist surrounding the structure, mystical forest surroundings, twisted tree roots embracing the building, foggy atmosphere, warm golden lighting, cinematic composition.
