Create a square 1:1 2x2 grid that visualizes four fictional classic fantasy books. In each panel, show a [Main Object] transformed into a miniature diorama, with the [Inner Scene] visible inside the open pages. Include tiny original main characters battling shadowy villains or monsters, a floating old-style fantasy map overlay near the upper-right area of each panel, and small ink bottles and quills placed around the book exterior. Use a [Background] with a clean studio presentation and warm parchment tones. Make the image richly detailed, handcrafted, magical, and suitable for a YouTube thumbnail. Keep all book titles, maps, emblems, characters, and worlds fictional or owner-provided; do not use real book titles, protected fantasy franchises, copied cover art, recognizable characters, exact maps, e-readers, modern clothing, messy desk clutter, real logos, private information, extra watermarks, unreadable accidental text, or low-resolution artifacts. Output aspect ratio: 1:1.
