Twillthrins Hollow

At the end of the bend in the river Cend lies a cleft in a large spike stone that could be a hill, if it wasn't so steep. Beyond the cleft there is a strange place, dark but not, colorful and musical. The sound of the river babbles through like a dark song. Twillthrin sings with the song of the river and lures in those who hear it. They sing and feast and dance and rejoice. But beware the hollow on the night of the full moons. Twillthrin has to pay his due. Through the song and dance the courts are called to bid a call. A guest they leave and a guest they take, lest Twillthrin tarry no more, and return home.
