The Baron of Magister Valley is a fantasy novel by American writer Steven Brust, set in the fictional world of Dragaera and part of the Khaavren Romances. Like the other books in that series, the novel is heavily influenced by the d'Artagnan Romances written by Alexandre Dumas, and is written by Brust in the voice and persona of a Dragaeran novelist, Paarfi of Roundwood, whose style is a tongue-in-cheek parody of Dumas, matching both his swashbuckling sense of adventure and his penchant for tangents and longwindedness.
