Erling Skakke made himself ready to travel, fitted out ships, and had
with him King Magnus, together with the household-men who were on the
spot. In this expedition were the king's relatives,--Arne; Ingerid, King
Inge's mother, with her two sons; besides Jon Kutiza, a son of Sigurd
Stork, and Erling's house-men, as well as those who had been Gregorius's
house-men; and they had in all ten ships. They went south to Denmark to
King Valdemar and Buriz Heinrekson, King Inge's brother. King Valdemar
was King Magnus's blood-relation; for Ingebjorg, mother of King
Valdemar, and Malmfrid, mother of Kristin, King Magnus's mother, were
cousins. The Danish king received them hospitably, and he and Erling
had private meetings and consultations: and so much was known of their
counsels, that King Valdemar was to aid King Magnus with such help as
might be required from his kingdom to win and retain Norway. On the
other hand, King Valdemar should get that domain in Norway which his
ancestors Harald Gormson and Svein Forked-beard had possessed; namely,
the whole of Viken as far north as Rygiarbit. This agreement was
confirmed by oath and a fixed treaty. Then Erling and King Magnus made
themselves ready to leave Denmark, and they sailed out of Vendilskage.
