That Dam city (pun intended)
Fallcrest is the largest town in the Nentir Vale, only slightly too small to be called a city. It is built across the dam that forms Lake Nen, with dry-land segments on either side. Generally speaking, the landlocked portions are more affluent, while the dam-folk are poorer. After all, who wants to live with a lake on one side and a hundred-foot drop on the other?
