Vipers Lair Cave World

Viper's Lair Cave World is a vanilla survival server built around a single idea: the entire world is one giant cave to explore and survive in. It runs on Minecraft 1.21.4 and keeps rules minimal while using custom data packs to support the underground-focused experience. Structures are adapted to fit the setting, with things like villages, strongholds, and ocean monuments modified to generate underground. If you want a challenging survival world where exploration happens below the surface, this cave-only map is designed for that.
