De zwaardvechter Beryl Gardenant runt een dojo in de binnenwateren. Wanneer zijn voormalige leerling en commandeur in de ridderorde Allucia verschijnt, wordt het rustige leven van Beryl op zijn kop gezet: stadsdrukte, oud-studenten, nieuwe vrienden, gevaarlijke vijanden. Allemaal te veel! Maar dankzij jarenlange training heeft hij ongelooflijke vaardigheden en de bijnaam "Backwater Swordmaster".
