A castle visited by Gawain.
He found its inhabitants distressed because the castle’s lord, Mahardi, was scheduled to fight a duel against a fearsome knight named Reimambram of Zadas. Mahardi, however, had fallen deathly ill.
The duel was to decide the fate of Behalim, Mahardi’s sister, whom Reimambram wanted to obtain. When Mahardi died, Gawain agreed to fight in his place. He defeated Reimambram and saved Behalim.
