昆虫のような生物と根が広がる生物発光する地下都市

A subterranean metropolis carved into glowing fungi and bioluminescent caverns, illuminated by phosphorescent waterfalls. Strange, insectoid creatures navigate bridges made of woven roots. The air is thick with a gentle, otherworldly mist. Above, faint outlines of colossal mushrooms form a living canopy. Style: Dark fantasy concept art with elements of bio-luminescent surrealism, inspired by the alien landscapes of H.R. Giger and the subterranean worlds of Wayne Barlowe.
