Gawayn is a French/Italian animated series created by Jan Van Rijsselberge, debuting in Italy in 2008. The story takes place in a Camelot, where a young knight-in-training named William is joined by his mentor, Sir Roderick, and his two equally young friends, an apprentice sorceress named Elspeth and a sage-in-training named Xiao Long, to undo a curse that causes the Princess Gwendolyn to shrink.
