The Lutece Door is a visually striking portal with an Art Deco design, featuring intricate geometric patterns and symmetrical motifs. Its frame is constructed from polished brass with a glossy finish, adorned with steampunk-inspired gears and cogs that appear to move subtly. The door itself is made of dark, stained wood with a smooth texture, centered by a large, circular window of frosted glass that emits a soft, ethereal glow, hinting at its otherworldly function.
