11 The Underworld is the network of subterranean caves that runs beneath the surface of Calligo. Cave entrances open from the surface map and lead into procedurally configured cavern rooms that hold most of the late-game crafting resources, several unique hostile creatures, and the only safe way to obtain Superior weapon tier components. The Underworld is pitch black; standing torches or hand-held torches are required for any meaningful exploration.

33 As of the most recent observed builds, the Underworld is configured as two stacked levels. The upper level is reachable directly from surface cave entrances and contains the bulk of iron, coal, and stone formations. The deeper second level was shipped with the avatar overhaul and contains the rare metals and resources needed for Weapons and Armours in the Superior tier.

55 Layout and Access
66  
77  
88 Surface cave entrances are scattered across the continent and are marked with cave-mouth iconography on the world map. Entering a cave loads a procedurally generated layout assembled from module types: dead-end rooms, corner rooms, branching junctions, and four-way cross-sections. Each entrance leads into the upper level; deeper passages descend to the second level.

1010 The Hand Cart is the only vehicle permitted underground. Pack horses, carts, caravans, and other surface vehicles do not pass the cave threshold. Resource trips therefore rely on Hand Carts running in convoys, often with armed escorts because the cave creatures are aggressive and the layout funnels combat.

1414 Two extraction patterns appear underground: small nodes scattered along cave floors that mine with a few pickaxe swings, and large cubic formations that require mining platforms and stairs to reach. The cubic formations yield single large items that fit only on a Hand Cart.

2222 Cave-in Cycle
2323  
2424 Every Underworld instance is on a cave-in cycle that runs between eight and thirty-six hours. When the timer expires, the entire cave system collapses, destroying every structure inside and resetting the procedural layout for the next cycle. A four-hour warning window precedes the collapse, telegraphed by falling rocks every one to ten minutes; players noticing this signal should evacuate any Hand Carts and salvage stored materials before the timer hits zero.
2525  
2626 Because the cycle is long but the warning is short, the standard pattern is to run several short trips per cycle rather than build a permanent underground stockpile. Long-term resource storage belongs in a Settlements surface warehouse, not a buried chest.

2828 Buildable Structures
2929  
3030 Construction inside the Underworld is intentionally restricted. The build menu only exposes a short list of cave-suitable items: firepits, sign posts, standing torches, storage chests, mining platforms, and mining stairs. Walls, gates, and most fortification structures cannot be placed underground.

3232 Tips for Underworld Runs
3333  
3434 Run in groups of three or four whenever possible: one player mining, one hauling on a Hand Cart, one or two screening Bats and Cave Wolves. Carry a lit torch at all times. Drop a Standing Torch at any junction the team plans to revisit so the route home stays visible. Watch the falling-rock signal carefully; a cave-in eats stockpiles whether the team is inside or not, so the safer pattern is to surface twenty minutes before the timer is up.
