Old Marsh

From D&D Wiki

Old Marsh is a city formerly governed by a strict Elven clan dedicated to the magicks of the Fae. After a mysterious wind swept into the city approximately 13000 years ago, a majority of the clan disappeared and those who still remained fled and moved the city to Marsh. In the last 5000 years, the area has been inhabited by pirates and outcasts, creating a lawless city within the old castles.
