Generate a massive symmetrical alien AI megabase inspired by an ancient extraterrestrial Dyson sphere. The base consists of three vertically stacked hollow spheres connected by a glowing energy core, surrounded by smaller interconnected satellite spheres linked with glass tunnels and mechanical arms. Use dark futuristic materials, exposed machinery, cyan and purple lighting, and dense sci-fi detailing. The interior should be a fully functional survival base with automation, storage, farms, villager trading, research labs, and a central AI reactor chamber.
