Caverin was the owner of the reputable inn of the Horse and Four. He is described as a bald, portly fellow.
In the Chronicle Edit
After Caverin hires Kvothe to be the musician of Horse and Four, Ambrose Jakis arranges the inn to be bought out, and hires a new innkeeper to prevent Kvothe from getting a job as a musician. Kvothe eventually ends up working at Anker's, a much less respectable inn for a much smaller salary.
