Friend of Guiron the Courteous in Palamedes.
He was married to the Lady of Malehaut, who loved Guiron. Danain’s wife and friend nearly engaged in an affair, and Danain nearly slew them for it. Instead, he abducted Bloie, Guiron’s damsel. They clashed in combat over the woman, and Guiron was victorious. The two knights reconciled when Danain saved Guiron from a murderous knight named Helain.
Danain fell in love with a maiden named Albe and became involved in a complicated feud between Albe’s family and the clan of Helyom. Eventually, he participated in a tournament at Camelot, received a mortal wound, and died at Malehaut.
