A maiden championed by Gawaine.
A terrible warrior giant named Reimambram tried to seize the young lady. Her brother Mahardi agreed to champion her, but perished before the combat could take place. Gawain, who had rescued Behalim from a wild woman in the forest, agreed to take the combat in Marhardi’s stead.
He defeated Reimambram and made him swear fealty to the maiden.
