Abridged History of the 10th Age
The Steinnvel is a huge fortress complex that lies just outside of the cultivated regions of the Tviervith valley. It is large enough that it maintains its own folk-hall as well as the massive fortress proper. The hall is dug directly down below the fortress and features many impressive works of dwarven architecture, including several long open caverns carved to look like a forest made of emerald and silver.
Steinnvel has never been captured by enemy hands, and has proved to be an invaluable defense against raiders from the Claulan Gap. The only time in living memory when Steinnvel was ever thwarted as a guard post was during the War of Maren’s Crown (X392-X402) when the border-counts of Claulan raided into the Feindal valley faster than Steinnvel’s forces could respond.
