Unferth is the son of Ecglaf. He slew his brother like Cain, but sits at
the king's feet in the Danish court. He is the one who boasts at Beowulf and tells him that he
could never defeat Grendel because Beowulf is not brave enough. However,
he later lends his sword, Hrunting, to Beowulf right before he battles Grendel's mother. This is not Unferth, but
is just another valuable image.
