(No sky, no light, no sunshine), (underground world, darkness, depth, deep underground world), Create an image of an underground fortress located deep beneath the Earth's surface. This fortress should be depicted as a robust and intricate subterranean structure, designed for survival and defense. It should include multiple layers and chambers, with thick walls, reinforced gates, and possibly hidden entrances. The fortress should be built within a vast underground cavern, surrounded by rock formations and possibly underground rivers or lava flows. The lighting should be minimal, coming from artificial sources like torches or luminescent minerals, creating an atmosphere of secrecy and resilience. This fortress represents a last bastion in a challenging underground environment, built to withstand threats and time.
