Designs deliberate subterranean space in a live Minecraft Java world — cave systems, cavern halls, ravines, lava tubes, mines, vaults, and the surroundings of an underground base — as opposed to the random vanilla caves the world already has. Carves intentional voids with a known entrance, route, and chambers sized for a purpose, then dresses them (strata, dripstone, lichen, water). Tier-3 leaf, invoked by build-natural-world / build-structure / build-settlement.
