A magic castle in the legends of King Arthur, in which it is said the Holy Grail was kept. It was guarded by two lions. Lancelot tried to enter it by his own strength, but instead of leaning on God for guidance, he was struck dumb by a fiery wind. In this state he remained for fourteen days without food or drink.
