A set of modular ancient stone ruin blocks — worn medieval fantasy style. Includes full blocks, half blocks, cracked blocks, corner pieces, and arch fragments. Each block is made of mossy, weathered stone with chipped edges, broken corners, and surface erosion. Designed to fit together in any rotation, with clean top/bottom and side alignment. Stylized semi-realistic texture, no debris attached, clean silhouettes. On a neutral or transparent background."
