Kai
The seneschal of King Arthur, known in the French romances as Messire Queux, or Maitre Queux or Kuex. He is prominent in the Morte d'Arthur. In the tale of Kilhwuh and Olwen in the Mabinogion, he is identified with a personage whose "breath lasted nine nights and days under water and who "could exist nine nights and nine days without sleep." A wound from his sword could not be cured; he could make himself as tall as the highest tree, and so great was the heat of his nature that, during rain, whatever he carried remained dry. Originally a deity, a rain-and-thunder god, he had apparently degenerated, through a series of mythological processes, into a mere hero.
