Among the River Kingdoms, some realms hold together through magic or through threats. Lambreth is held together by the sheer physical power of Lord Arnefax, an Andoren knight banished for his excesses and crimes against nature. Leading a company of 50 heavy cavalry (unusual in the River Kingdoms, where bandits rarely use heavy armor or heavy horse), he rules from the city’s small citadel and makes frequent nocturnal visits to his borders riding a powerful nightmare. His people are both terrified of his night riders and their shadowy dogs, and perversely proud that Arnefax is powerful enough to keep their lands free and unmolested by cattle raids. The few occasions when Lambreth lost cattle, the ensuing retaliation usually involved the death of two people for every cow or sheep stolen — often by lynching and burning. Few dare challenge the Andoren’s ruthless rule.
