The giant caverns generated by this mod differ slightly from the default giant caverns found in some mapgens, they use an additional source of noise to generate more ledges and horizontal floors. And should it be breached, the exotic Primordial cavern layer can be found beneath. Unconventional methods of penetrating the Slade do exist, however. Its dead hollows rest on a layer of Slade, a dense material impervious to conventional mining efforts. There are signs that life once existed here but it is now long gone. These caverns are filled with dangerous substances, though there are riches to be had as well mineral growths fed by the heat and pressure and bountiful fuel sources.Īt the very foundation of the world lies an ancient impenetrable realm. Twisting rivers connect the various caverns of the Sunless Sea.īelow the Sunless Sea are seas of a more dangerous sort: lakes of oil and the magma ocean.

The caverns of the Sunless Sea are vast in extent but are mostly flooded with water, and below the surface grows treacherous Snareweed and underwater citadels of softly-glowing Cave Coral. Familiar growths crowd its fertile shores, with Tower Cap, Goblin Cap, Fungiwood and Spore Trees able to take root in this relatively hospitable zone. Smaller plants that can be found here include quarry bushes (farmable for their spicy leaves) and dimple cups (whose eponymous parts can be ground to produce a brilliant blue dye).Īfter the third layer are the shores of the Sunless Sea, the ultimate destination of all water that flows downward through the twisty caves of Minetest. In caves too dry to support biological life enormous glowing crystals grow instead. In the hotter areas the vicious Bloodthorn grows, with wicked spines that suck moisture from anything they can pierce. The frigid Nethercaps, blue-tinted mushrooms leaching heat out of their environment in ways that shouldn't be thermodynamically possible, fill their caverns with ice and snow. The coal-black caverns of the Black Cap forests, rich with carbonaceous deposits that have accumulated over millions of years and lit by smouldering Torchspines, are found here. In the third cavern layer yet stranger forms of life flourish in the hostile conditions. Smaller growths found here include plump helmets, cave wheat, pig tails (a fibrous fungus that can be grown and harvested for thread) and sweet pods (whose fruiting bodies can be milled for sugar or processed into syrup). Tunnel Tubes grow in the hottest regions - tall, curved stalks with fruiting bodies at the tips that burst violently when ripe. Spore Trees sprout in the warmer and wetter corners of the caverns, raising a climbable three-dimensional mesh or hyphyae above the ground that emits a gentle rain of spore powder. Here you can find Goblin Cap mushrooms, the squatter cousins of the Tower Caps. The next layer down has more exotic growths.

Also found in this region are plump helmets (an edible farmable mushroom), and cave wheat (a pale grass-like growth whose seeds can be ground for flour). These provide a source of underground wood.

The uppermost layer is home to relatively conventional tree-like fungal growths of Fungiwood and Tower-Cap mushrooms. As one goes deeper one will find increasingly bizzare flora and exotic environments that provide new challenges and opportunities for players. The underground is divided into a number of cavern 'layers' with a variety of biomes and other features distributed throughout. Inspired by the world of Dwarf Fortress, this mod adds a series of vast cavern layers to the depths of Minetest with a variety of biomes that are populated with the flora of Dwarf Fortress.
