Hell is included in the game's languages, and generated names for people, sites, regions, etc., can contain the word hell. Hell is a popular alternative name among DF players due to its hellish overtones, but it is rarely referred to as such in-game. Nearly all other references in the game, including dialogues and descriptions, call it Underworld or underworld. Upon first discovery, the place is referred to as an eerie cavern. It will be burned to ashes and levers will often be useless for blocking them off through bridges because those demons are extremely fast. If not properly prepared, breaching into the Underworld can wipe the entire fortress in seconds. In worlds generated without demons, the Underworld is empty and goblins are not present either, but goblins can still appear through historical deep dig disasters. Clusters of webs can be found scattered across the Underworld's surface, marking the presence of demons able to spew webs as a form of combat. It is yet unclear whether the number of demons is finite in information exported from the legends screen, the population of demonic species is listed as "unnumbered," a descriptor usually reserved for ants, worms, and other omnipresent vermin. If you dig down through a hollow adamantine pillar, but had previously blocked off the particular hallway with a drawbridge and raise it, you can discover the location of all adamantine on the map with no negatives.ĭemons spawn on the edges of the Underworld much like animals do on the surface demons thus spawned will be content to meander, without going out of their way to extinguish all life they can reach. Its rough floor slopes up and down, making it possible to walk around and explore should you get an adventurer down there. The Underworld expands out in all directions without bound, with a height varying between 1-4 z-levels. The initial demon invasion may reach well over a hundred attackers, sometimes leading to FPS death before they even reach the fortress itself. It is inhabited by demons who, when first encountered, will immediately rush to the nearest exit they can find, typically leading to overwhelming amounts of fun. The Underworld takes the form of a massive open cavern of slade, dotted with giant, bottomless eerie glowing pits ( *) which will instantly kill anything that falls into them (unless floors are constructed over them). The large red areas are eerie glowing pits, which go all the way to the lowest z-level in the map.
