Top-down 2D Dungeons & Dragons battle map, 30x30 grid, 5-foot squares clearly visible, ancient ruined arcane library carved inside a mountain cavern. The room is a vast circular and rectangular hybrid hall with symmetrical ruins and broken stone architecture. At the exact center stands a massive robed skeletal statue holding a large ancient tome, with one glowing green magical eye. The environment is a crumbling library interior: collapsed stone shelves, shattered bookcases, scattered ancient tomes, and broken arches carved into rock walls. The floor is dark stone tile mixed with rubble and debris. Include several tall broken pillars for cover, ruins of archways forming partial chokepoints, piles of rubble creating difficult terrain, and faint glowing green magical mist drifting in several areas of the room. Lighting is dim, atmospheric, eerie, with soft green highlights coming from the statue’s eye and faint arcane glow in the mist. The map is designed for tabletop RPG combat with clear tactical readability. No characters. No text. No labels. Clean visual clarity. The grid is evenly spaced, perfectly aligned, and integrated into the floor design (subtle but visible white or faint gray lines). Style: dark fantasy, highly detailed, painterly but readable for VTT use, Pathfinder / D&D style battlemap. Camera: perfectly top-down orthographic view. Resolution: 4096x4096 or higher. Ver más
