Settings: The Twins
As per the name, the Twins are a pair of castles, fortified and connected by a bridge that spans the Green Fork River. The Twins are the ancestral home of House Frey, and they have grown wealthy over the years by charging a toll to those who wish to cross. And there are quite a few good reasons to cross; parties from the North that intend to head to Riverrun can save themselves several days of journeying by crossing the Twins, while those that travel from Riverrun with the intention of heading North almost always cross the Twins in order to avoid the swampy marshland of the Neck. The head of House Frey, Lord Frey, a prickly old man with progeny in the double digits, determines the toll, depending on the party intending to cross; the payment isn’t always gold.
