The noble knights of Bretonnia are bound by duty and honour to fight for their king, and defend their lands from invaders. When the Lord of Bastonne falls ill, his two sons Calard and Bertelis are plunged into conflict as suppressed rivalries surface. As a horde of goblins swarms out of the forests, the knights gather their forces to repel the foul beasts, little suspecting that the true enemy has yet to reveal itself.

Knight Errant is the first ever novel about Bretonnian knights from Mark of Chaos author, Anthony Reynolds.
