Frotho fell under the bad influence of Grep and certain other advisors until the arrival of Erik, who killed many of them and exposed Hanunda's infidelity.
Name spellings are derived from Oliver Elton's 1905 translation, The First Nine Books of the Danish History of Saxo Grammaticus, via Wikisource.
The second part, which roughly began in Book V, saw the emergence of the virtuous Ericus as a new counselor who guided the king towards the path of Fortitudo, Temperantia, and Constantia.
[1] The new period described Frotho III as a peacemaker and legislator (law-giver[2]) with Saxo claiming he was responsible for the Danish hegemony.
Viktor Rydberg considered Saxo's account of Frotho's reign to be a historicized version of the Vana-god Frey, which was particularly demonstrated in the section detailing the king's war against the Huns.
