Dwarves have taken many terrains for their home but they love the plains the best. Their communities are based in pits where they mine the resources for their wares. The community can change drastically depending on the needs determined by the conditions in a particular area.
Characteristically there is a wall and towers of some sort at the rim of the pit. The main road is always a downward spiraling road to the bottom of the pit. From the top to the bottom where mining has stopped is were homes are built. Homes are built directly into tunnels where the particular resource of the area has run out. Dwarves are a hardy lot and will often live in the tunnels they are digging in if there are no suitable tunnels for homes.
Their wares and crafts usually consist of gems and stone. Where stone is not common dwarves of developed some interesting some interesting techniques for building including; adobe and cement.
