The moon of Haven contains a multitude of underground caverns and expanses that is collectively referred to as “Subterránea”. Haven’s caverns expand deep underground into large sections containing microclimates due to the influence of the Yggdrasil’s, giving rise to new ecosystems based entirely underground. In some locations, beautiful glowing groves of healing water dot with dense marshy grass, or large mushrooms rock gently from the fungal surface, glowing a serene blue. Some of these caverns have been populated with certain species choosing seclusion over living in the other districts with different cultures.
The Ybza’nxgi’k, also known as “Nax” to outsiders, is a growing settlement underground of the outer reaches of the Haven District home to the Purgatorian Worms within the Haven Federation, migrating into the caves after the leaving of Grand Protector Von Quinn and his presumed death by suicide as per Worm custom, to birth his offspring from his corpse to begin a new generation. Worms make their daily lives in the chitin-lined huts and complexes lining the major dark chasms of this region of Subterránea, holding markets for any adventurer that may come to bargain for their exotic goods.
The Bovilz Spire, sometimes known to Obsecrians as the Haven Node, is a small underground structure acting as an exit and relay node in the resource and personnel teleportation network used by Obsecrian gatherers. Officially speaking, it is an embassy established by Obsecrian gatherers for governmental interactions, but the layout of the supposedly official structure exemplifies the bizarrely casual nature of their initiative. It houses an 'orange bar'-- a bar that primarily serves orange juice, but still has some alcoholic beverages-- and the functional equipment required for it to act as a network component. Like all Obsecrian structures, the Bovilz Spire is a living structure that is capable of rearranging its inner organization on the whim of an Obsecrian housed inside and connected to the pilotsphere, the 'brain' of the structure. When official matters need to be attended to, the pilotsphere containment chamber can be rearranged into a sort of meeting room to match the size of the occasion. The Bovilz Spire rarely sees Obsecrian use after the rise of another economic initiative, but remains open to serve Obsecrian travelers and commoners alike.
In the deep Subterránea directly under the Yggdrasil tree, beautiful and thriving ecosystems of natural growth make their mark, home to a multitude of naturalist species such as Florans or Agarans. In these caverns, massive underground groves of vivid green grass, animals, and flowing waters dot oases found underground, and other places such as glowing mushroom biomes and blue-grass groves can be found.
Precursor ruins have also been found in underground regions of Haven.
Political Information
Subterranea is not an official district, as each underground region is simply controlled by the district above it. Most areas are relatively lawless, but Subtrerranea is one of the most diverse places in the Federation, and the people there tend to hold foreign connections to exotic places such as the Undercrypt. Because of its low population, most government officials pay little attention to Subterranea, something that many of its denizens prefer.
