Galaad, Galad the lord of Pastures, Glaalanz de la Terre des Pastures
The Saxon king of the Land of the Grazing Grounds, who joined King Rions’ (Ryons) invasion of Carmelide (Cameliard).
After Arthur defeats Rions’ army at Aneblayse, Merlin vowe a magical fog which made Galahad’s army collide with the forces of Amant, another enemy of Arthur. The two armies decimated each other.
Is he perhaps identical with Glaalant?
