then comment that they are "not yet warmed by the blood of slaughtered men". The girls continue to grind even harder and the shafts of the mill-frame snap. They then sing a prophecy of vengeance mentioning Hrólfr Kraki, Yrsa, Fróði and Halfdan: Now filled with a great rage, the girls grind even harder until finally the grinding mechanism collapses and the magical stone splits in two.
