One of the most famous Arthurian legends, Sir Gawain and the Green Knight is the story of one knight's lesson in honor, discipline, and chivalry. With green skin, green armor, and a green beard, a warrior arrives at King Arthur's castle and challenges the lord's warriors. Only Sir Gawain is willing to accept. The challenge is simple: Gawain gets to strike one undefended blow against the Green Knight, but then in a year and a day, the Green Knight will get his turn to strike. They shall meet at the Green Chapel for their final showdown. Gawain lands the blow and severs his opponent's head, but the Green Knight doesn't die. Now Gawain has a year to find the Green Chapel and meet his fate.
