A country visited by Gawaine in the Vulgate Lancelot.
The son of its king had been slain, and the king accused Hasart, his seneschal. Gawaine agreed to champion Hasart in judicial combat, while the king secured the services of Gaheris, Gawaine’s brother. Fortunately, Gawaine recognized his brother and ended the combat before either was seriously wounded.
