Hollows of Welt

The planet of welt, is hollow in certain areas, with extensive cave systems with underground hydrospheres and small suns of their own capable of supporting life. Hollows are by difference to the cave systems absolutely massive, often with their own biospheres. At the bottom of the outer first shell lie the inner shells of Welt.
Entrances to the underworld cave systems (or Hollows) and inner shells can be found all over Welt. The Other Races and the Dalmer often create underground settlements. A point of difference is that the Dalmer generally excavate their settlements while the other races settle existing cave systems of the Hollows.
===The Dalmer and the Hollows===
Despite the safety of the underground, the hollows aren’t immune to extinction events such as earthquakes that bury entire ecosystems alive. The Dalmer invest immense amounts of resources, research and engineering into keeping their underground settlements safe from such events by as they are filled with machinery, records and treasure.
===The other races and the Hollows===
Other races who live in the Hollows of in the Inner shells of Welt are known as Inner Weltians.
Hollows are often the origins of legends and myths among the other races. It is not uncommon for other races to have creation myths of their race emerging from caves to the surface from faraway lands.
Some other races build underground cities with functioning gardens to feed their populations of 15k-20k families are not rare in some cultures.
===Biosphere of the Hollows===
Cave systems and Hollows have thriving biospheres thanks to ingenious ways the lifeforms there have access to light, and by extension photons. Some systems work thanks to buried suns, smaller versions of actual suns. More commonly, cave systems can support biospheres thanks to some bioluminescent chemosynthesizing plants that grow on chemical compounds (most often ammonia, sulfur and iron) found on cave walls that dispense them from requiring photons, as such they only require water to survive and thrive. These plants emit bioluminescence powerful enough to supply photons to other plants, this creates proper underground biomes. Finally, some biomes get their light sources from Piezoelectric crystals that emit light from being pressurized by the earth that surrounds them. Eventually, these biomes can support animal life and other animate beings.
As a result of these unique biospheres, caves from which creatures spew out as the sunsets aren’t uncommon. This leads to legends of cursed lands who are tranquil during the day but bloodbaths at night, possessed by devilish creatures who come from inside the earth.
===Buried sun===
Buried suns, Proserpines or interior suns are giant condensed gas spheres that emit energy in the form of light with little heat. These interior suns 100 km (some estimated as large as 1000 km have been observed)  across provide light to advanced inner-weltan civilizations, these are natural phenomena from the planet's core known as Buried Suns. They are suspended in the air until they run out of gas and they condense into a dense metal that, if powered, remains in place. These spheres are thought to come from the center of the earth and they eventually rise to near the surface where they act as miniature suns in hollows or cave systems.
Immovable rods are made from the metal of extinguished buried suns.
