Build a 100x100 open FFA PvP map for Minecraft 1.7.10, optimized for up to 50 simultaneous players. Theme: ASTRAL / COSMIC RUINS. Create a large open battlefield, NOT a small enclosed arena. Use cobalt blue, cyan, white, black and gray. Add ruined quartz structures, broken pillars, rocks and subtle glowstone accents. Keep at least 70% of the map open and easily traversable. Add: * 16–24 well-distributed spawn points * multiple wide routes between all areas * large open central combat zone * several secondary fighting zones * small elevation changes only * limited cover that never creates camping spots NO water, lava, giant crystals, high walls, mazes, tight corridors or building interiors. Avoid bottlenecks and dead ends. Players should be able to reach different areas immediately
