Terren City

This great wonder of the Decona region is a massive sprawling city existing entirely within the Terren Caves. Though the lighting is dim compared to sunlight, of course, the city is lit all throughout, enough that it's quite easy to get around even without a light source of your own. The ceiling of the cave is very high, so buildings of as many as ten stories high are not uncommon. In fact, buildings of this height are a necessity, since there is no room for the city to expand outwards safely. Though many of the buildings are residential, there are numerous restaurants and businesses scattered throughout, all importing goods from nearby Denton Village and Graucan Port. Greenhouses are also quite common, since they allow residents to grow their own herbs and vegetables without needing to import from the surface; the Terren Gym is actually located on the first floor of a massive multi-story greenhouse near the center of the city. There is a central road that cuts straight through the middle of Terren and leads out into the dark cave tunnels on either side of the city.
