Fogstone

Fogstone, or homichlite (Nebulonic: ucutóvin; Sajem Tan: tözenţefam), is a mineral found in the mountainous regions of the New Continent, notably Nebulonia and the Northeastern Mountains. Ice crystals and rock sediment come together to form this sedimentary rock, which lives far under the mountains in the cold. When the rock is exposed to the open air, it quickly begins to decay, releasing melted ice into the air as fog. The practice of fog mining has grown among the Nebulones to increase the availability of fog, which is important to their agricultural practices.

History
According to Nebulonic folklore, fogstone was first discovered when a great mountain exploded in the Great Jælmekín War, long before the Nebulones moved to Sajem Din. The emission of fog was so great that it changed the Nebulones' way of life forever: with reduced visibility, they had to adapt. The surrounding flora changed as fog plants began to thrive: before, with so little moisture in the air, they could not grow very tall and they did not survive long. However, just two centuries after the explosion, large swaths of the mountains were covered in dense fog forests, and the growth of fog crops had long replaced older agricultural methods. It was agreed that the explosion turned out for the better.

After the Nebulones left the Northeastern Mountains, they went in search of another land rich in fogstone. They bore through many mountains along their long trail in search of a vein. They came upon a mountain chain bathed in fog, with fog mines dotting the mountains. The Nebulones discovered that the range had been abandoned by another people who had also specialized in fog mining and fogriculture. The Nebulones settled here and named it Nebulonia.

Fog pollution
In recent years, heavy mining practices have led to the discovery of a new mineral, "salty fogstone". The ice in this rock is high in salt, so, when it decays, it releases saltwater into the air. This salt usually harms fog plants, though some, such as the brackish ginkgo, thrive on it. Brackish ginkgo forests have been planted to offset the salty fog so that other fog plants will be protected.
