Since so much trade passes through, he figures that the rest of the world is coming to him anyway, so why should he have to go there? In his youth, Guthin made a name for himself because how he would stand up to people thrice his size if needed. This is why his tavern is only rowdy for as long as he's prepared to deal with it. Guthin married in 1334 and has three children together with his husband Fedelin Bolster. The oldest two works at the tavern alongside Guthin.
