The Upper Dark

The Upperdark extends from the surface to a depth of about 3 miles. Varied races inhabit this region including chitines (basically humanoid spiders), Dark elves (Drow), Dwarves, Deep Gnomes, and some of the more feral goblinoids. Scouts from deeper races would often venture into Upperdark in order to trade with or prey on the races native to this area. Most Upperdark inhabitants traffic with the surface world in some way, either trading with or raiding their upstairs neighbors in hopes of getting more resources and slaves for their respective communities. The only exception to this was the Dwarves as for the most part the Dwarves are not evil and preferred to stay in the Upperdark as it was more for defending the dwarven cities since the rocks were sturdier and had some magical metals infused with the rocks such as the highly banned metal Adamantium. No underdark community is ever really friendly with another, but Upperdark settlements often observe wary truces with their neighbors however all agree on one thing. Should a threat arise involving the sealed ones most communities will join force to either re-seal the entities or helping those to escape so they can tell the tale of what actually happened down in the Underdark.

The Upperdark's main import from the surface is slaves. Slavers from the more evil-aligned cities in the Upperdark make frequent excursions into the light capturing new slaves for use as either labor or food. They also trade for textiles, grains, fruit, and weapons. Their exports include raw ore, refined metals, gems, native underdark plants, and even the banned metal Adamantium.

In the Upperdark there aren't many sealed entities only a few as they are powerful mortals who dwelled into the deep arcane with some forbidden magic mixed in. They are considered the least threatening of the sealed ones hence why they were sealed in the upper dark and should they ever be released and enter the surface level a moderate amount of damage will be done however with the advancement of arcane knowledge and some technology Slayers will be able to kill these sealed ones or re-seal them away. Some areas may be difficult due to the effects of the Arcane Fracture and the risk of getting Weave Sickness.

Cosmic Invasion effects
Since the cosmic invasion many of the races perished leaving only some drow, dwarves and deep gnomes to survive, fleeing onto the surface. Some of these sealed ones were released due to the seals being weakened by the affects of The Shatterer. While some of the sealed entities leak their influence into the Upperdark in attempts to unlock the seals themselves but also causes odd things to happen in the Upperdark. Out of all of the layers the Upperdark has the least amount of strange things happening as only the leaky seals seem to effect the various environments making them more wild as well as cause some minor rifts between realities.
