The Town is a small, respectable fishing town with a population of about 2,000. The inhabitants are relatively sober, hard working and amiable. There are adequate facilities for justice and law-enforcement—debtors and bankrupts are dealt with particularly harshly. Fishing is the main industry but there are some tiny farms in the neighbouring countryside. The town boasts a small weekly market to which traders are attracted from two larger towns, Burle and Seaton, each some twenty miles away (Burle inland to the northwest, Seaton along the coast to the east).
