Just now I published part V of the Thidrekssaga: Detlef the Dane.
The hero Detlef comes to Dietrich's court, initially as a servant, but he pawns off the heroes' equipment to give a great feast. Once that is discovered he has to fight a duel of strength against Walther, and wins. Thus he becomes a hero of Dietrich. Also, this part shows the start of the quarrel between Witig and Heime.
