Terralith Underground Structures are a group of six structure types added by the Terralith mod that generate inside cave biomes and the caves of other biomes. They are built from one shared underground family in Terralith, with five structures in the main underground set and one dungeon in its own set: the Frosted Dungeon. A seventh design, the underground cabin, is shipped by Terralith but is not placed by any structure set, so it never generates. The structures are a ruined oak cabin, a giant bee hive, a mining outpost, an old refinery, a sunken tower and the frosted dungeon. Each one stands on a cave-like biome, so a player exploring caves is the most likely to find them.

Generation
All six placed structures use the surface_structures generation step and a jigsaw template. Each one picks a start height at random between Y −40 and Y 40, which places them among the cave layers rather than on the surface. Terralith's #has_structure biome tags decide where each structure may appear, listed per structure below. Rarity is set by each set's spacing, as tuned by the pack's sparse-structure settings; the observed counts below are the best guide to how common each one is.
Within their set, the structures are weighted against each other. The mining outpost has the highest weight (13 of 36), followed by the ruined oak cabin (11), the old refinery (5), the sunken tower (5) and the giant bee hive (2). The frosted dungeon is in its own set, with a spacing separate from the main set. In a 26 km² sample, the old refinery was the most common (52 instances), followed by the mining outpost (5), the sunken tower (2) and the frosted dungeon (1). The giant bee hive and the ruined oak cabin did not appear at all in that sample.
- Frosted Dungeon generates only in Frostfire Caves.
- Giant Bee Hive generates in Underground Jungle and Lush Caves.
- Mining Outpost generates in Deep Caves.
- Ruined Oak Cabin generates in Lush Caves.
- Old Refinery generates in Infested Caves, Fungal Caves and Deep Caves.
- Sunken Tower generates in Underground Jungle and Lush Caves.
Fear Nightfall changes the cave biome mix. Infested Caves and Frostfire Caves are weighted at 6× in the pack, so the old refinery and the frosted dungeon are the most likely to appear in horror caves. Lush Caves is weighted at one third of its usual share, which lowers the chance of the oak cabin, bee hive and sunken tower in that biome. Infested and Frostfire Caves are part of the pack's horror biome set, so these structures sit in the most dangerous cave terrain.
Layout
Each structure is built from a fixed set of templates, so a given structure always looks the same inside.
- Frosted Dungeon is a single template, about 49 × 44 × 49 blocks. It is the largest structure in this group and the only one that reaches down into Frostfire Caves.
- Giant Bee Hive uses one of two templates, chosen at random. It is built to bury into the terrain rather than sit on top of it.
- Mining Outpost uses a small or a large template, with the large one about 34 × 30 × 34 blocks.
- Ruined Oak Cabin uses a small or a large template.
- Old Refinery is a single template, about 40 × 40 × 42 blocks.
- Sunken Tower is a single template, about 38 × 41 × 38 blocks.
The mining outpost, oak cabin, old refinery and sunken tower use the terrain-adaptation method that fits the structure to the surrounding ground. The giant bee hive is buried into the terrain instead.
Inhabitants
The Frosted Dungeon places Stray mobs inside it, making it the one structure in this group with a set population. The Giant Bee Hive places bees. The mining outpost, oak cabin, old refinery and sunken tower place no mobs of their own, so any hostile mobs near them come from the surrounding cave biome.
Loot
All five of the structures other than the giant bee hive use the shared terralith:underground/chest table for their chests, so their chest contents are the same and differ only in how many chests each one holds. The table's notable entries are Enchanted Book and Arcane Essence, each at a 44% roll, plus Book at 47%, Rope at 75% and Glow Berries at 74%. The full list is shown in the table below.
The Giant Bee Hive has its own loot table with three guaranteed entries. It gives 11 to 15 honeycomb, 4 to 7 honey bottles, and one roll on Terralith's Royal Jelly loot table.

Tips
- The old refinery is the most common of these structures in this pack, so it is the most likely one to find. Look in Infested, Fungal and Deep Caves.
- The frosted dungeon is rare, appears only in Frostfire Caves, and is one of the pack's horror cave structures. It contains Stray mobs, so prepare for them before entering.
- Lush Caves is weighted down in this pack, so oak cabins, bee hives and sunken towers are harder to find there than in the stock mod. Underground Jungle is the other biome that holds bee hives and sunken towers.
- The mining outpost has the highest weight in the main set, but the old refinery was more common in the observed sample. Both small and large mining outpost templates contain chests worth checking.
