Cavern Tower: An Anime-Inspired Cave Fortress

An anime-style tower rises inside a dim, moss-lit cavern. The tower is carved from dark rock, adorned with glowing rune inscriptions, and emits a warm amber glow through arched windows. Stalactites hang from the ceiling; bioluminescent fungi and a crystal-clear pool reflect the scene. The composition uses a dynamic low-angle perspective from within the cave, with dramatic, high-contrast lighting and crisp cel-shaded linework. Moody fantasy atmosphere, vibrant colors, and a sense of epic adventure.
