At this time there was a king by the name of Northri, who ruled over a
part of England. Hroar often passed long intervals at the court of
Northri, supporting him against his enemies and defending his land.
Hroar married Ögn, the daughter of Northri, shared the royal power with
his father-in-law, and after Northri's death succeeded to the throne of
Northumberland. Helgi remained at home, and, by agreement with Hroar,
became sole King of Denmark.

In Saxo's seventh book, there is another version of the same story. The
features in which it chiefly varies from the version in the _Hrólfssaga_
are as follows.

Halfdan's name has become Harald; Hroar's and Helgi's names have become
Harald and Halfdan; Earl Sævil has become Siward, King of Sweden; Signy
has become a daughter of Karl, governor of Gautland, and wife of Harald
(Frothi's brother). Envy and the quarrelsomeness of Frothi's wife and
Harald's wife cause Frothi to engage men to murder Harald. Frothi tries
to avoid suspicion of being the author of the crime, but in vain; the
people believe he is guilty. When he seeks the boys of the murdered
king, to put them out of the way, their foster-parents bind the claws of
wolves under the boys' feet and let them run about and fill a
neighboring morass and the snow-covered ground with their tracks,
whereupon the children of bond-women are put to death and the children's
bodies torn to pieces and strewn about. This is done to give the
impression that the boys have been torn to pieces by wolves. Then the
boys are concealed in a large hollow oak, where food is brought them
under the pretence that they are dogs. Dogs' names are also applied to
them. The episode with the witch is present, but other men and women
with superhuman power are not introduced. The whereabouts of the boys
begins to be bruited about, and Ragnar, their foster-father, flees with
