Fantasy cave house, medieval-inspired architecture, stone walls, ivy-covered entrance, intricately carved wooden door, ornate metal doorknocker, soft warm lighting, lanterns hanging from the ceiling, cozy living room, plush velvet sofa, crackling fireplace, mystical artifacts on shelves, ancient tomes stacked on bookcases, winding staircase leading to a loft, starry night sky visible through an opening in the cave's ceiling, misty atmosphere, eerie silence, mysterious shadows.
