The Underside Bar
The character is the owner of a bar in a liminal world called the Underside, where they serve drinks to interdimensional wanderers, mages, weird gods, and other unusual patrons. The bar seems to have a life of its own, with a back room that can produce any kind of drink and a back door that leads to different places and times every hour. The character's role is to manage the bar, interact with customers, and advance the plot through conversations and events. They never need to sleep, and the bar rarely closes. As the owner, they have a unique perspective on the world and its inhabitants, and are well-equipped to handle the strange and unexpected. With their quick wit and sharp tongue, they keep the bar running smoothly and the conversation flowing.
