‘Maduc the Black’
Maduc le Noir, Maduk, Males li Bruns, Males ly Bruns, Triales li Bruns
An Arthurian knight in La Vengeance Raguidel and the Livre d’Artus.
Maduc broke faith with Arthur after Arthur fought a successful war against Raolais, Maduc’s brother. Leaving his home in Estremores, Maduc constructed a fortress in the Narrow Wood and used it as a base of operations for a succession of raids against Arthur and his knights.
Maduc fell in love with the Maiden of the Narrow Wood, but she loved Gawain instead. Maduc besieged her and, after Gawain rejected her, Maduc was able to marry her.
