Floating Chessboard

A magic artifact desired by Arthur and sought by Gawaine in a Dutch romance. It was owned by King Wonder, who would only relinquish it if Gawaine brought him the Sword with Two Rings. This sent Gawaine on a long series of interlocking quests, culiminating in his return to Wonder’s court with the sword. Wonder completed the trade, and Gawaine returned to Arthur’s court with the Floating Chessboard.
