Seven Kingdoms: Seowyn's Crossing
Barrows Lake is an southwest/northeast stretching body of water surrounded by the hills called the Broken Barrows. It is fed by Maren’s Run, and it is in this lake that the river called the Feywash splits off southwest towards Tavanion.
The Warforged town of Firsthome sits close to the Lake on the northwestern shore, and the town of Marwayn sits on the southern shore, in the crook where Maren’s Run heads south from the Lake. Since the Warforged have few needs for imports and do little exporting, there aren’t many boats heading across the Lake, unless they’re carrying Adventurers or Warforged travelers.
