The valley is a region that was created during the Eschaton, having previously been a naturally formed mountain range that held a dwarven kingdon, an elvish city, and other settlements in the near vicinity.
There are no extant records of the Eschaton, the sudden disappearance of magic and simultaneous seismic and weather events caused the near destruction of civilization and the death of much of the world population. Several centuries of rebuilding and recovery took place in the more intact occupied areas before exploration began, and the initial expeditions found an uninhabitable valley – high levels of volcanic and seismic activity produced poisonous gasses, lava, etc.
In 742 PE, the dwarves were the first to brave the cooling valley and begin exploration, setting up their first excavation near partial remains of their lost city. At this time, the area was still largely uninhabitable, though the southern side of the valley was more stable than the northern. This excavation has grown into the city of Hindohr.
In 890 PE, the first successful human expedition arrived from the kingdom of Malden to the north. Led by a man named Yhil, they found that the area had coolled and settled, and had been rapidly taken over by lush plant growth. He and his company established Yhilport near the mouth of the Suleskard River in 892.
When the dwarves of Hindohr and the varied races of Yhilport made it far enough up the river to establish the village of Tain, they found that there were other sentient occupants of the valley – in a secluded monastery east of the dwarven hold, named Qujing. The monks welcomed visitors and opened trade with the other settlers, but have been very cagey about when they arrived and established the site.
The prime export of the region is a strange mineral dubbed ‘azure piezium’ by the dwarves that discovered it. The mineral is a deep azure blue in color, and quality is established by the size of the stone and the amount of light it produces in a dim environment. Every piece discovered to date is the exact same color, and almost perfectly transparent. It was a gnome tinker that discovered that the stone produces a surprisingly strong, consistent electrical current when placed under pressure, and an industry has sprung up around the development of ways to exploit this feature.
Other Mining Products
Other than piezium, various other valuable minerals and metals have been found in varing quantities in the valley. These include, but are not limited to: emerald, tourmaline, zircon, topaz, ruby, jade, garnet, peridot, obsidian, gold, onyx, iron.
The soil of the valley is unusually rich, thanks in part to the recent volcanic activity. Common grains and vegetables tend to do well, as well as cherry and apple trees that have been established in the foothills. As well, coffee is beginning to be produced on a promising mountainside near Iona. As well, some rice is grown in areas near Yhilport, in the river delta.
Other Notable Features
The river is a powerful freshwater river that originates in the western mountains of the valley, flowing from an underground source with seasonal melt tributaries from both the north and south. If flows almost due west after descending from the mountains, also feeding into the Bullywug Swamp.
This is an area in the extreme eastern end of the valley, on the northern side of the river. This area has been given only cursory exploration, due to the inhospitable nature of the area and the presence of bullywugs, a froglike sentient race that harries and assaults intruders.
