Tearin

Tearin is a dwarven dominated nation. While some locations exist above ground the vast majority of the country is situated underground. Tearin is the only country in Vanor that doesn't recognise Vanoran as it's official language (although everyone is Tearin speaks it anyway) The capital of Tearin is Augasteel, which is nestled into a mountainside. It is partially above ground and partially underground however every part of the city is on the same level; the city is built into the mountain so you can travel horizontally and still move underground.

Tearin is currently at war with Aella after expanding into their borders, albeit underground.
