Yder

 

Yder was the son of Nuc.  He was also a Knight of the Round Table.

 

He fell in love with Queen Guenloie who said she would not marry him unless he brought her a knife belonging to two giants.  To get the knife, Yder slew both giants and in return she married him.

 

Yder is also said to have been married to the daughter of Guengasoain whom he and Gawain had killed to avenge Raguidel.
