They went to the Orkneys first of all, then to England, and he "got Northumberland as earldom," I vaguely hear, from Athelstan.
But Eric soon died, and his queen, with her children, went back to the Orkneys in search of refuge or help; to little purpose there or elsewhere.

From Orkney she went to Denmark, where Harald Blue-tooth took her poor eldest boy as foster-child; but I fear did not very faithfully keep that promise.

The Danes had been robbing extensively during the late tumults in Norway; this the Christian Hakon, now established there, paid in kind, and the two countries were at war; so that Gunhild's little boy was a welcome card in the hand of Blue-tooth.
Hakon proved a brilliant and successful king; regulated many things, public law among others (_Gule-Thing_ Law, _Frost-Thing_ Law: these are little codes of his accepted by their respective Things, and had a salutary effect in their time); with prompt dexterity he drove back the Blue-tooth foster-son invasions every time they came; and on the whole gained for himself the name of Hakon the Good.

These Danish invasions were a frequent source of trouble to him, but his greatest and continual trouble was that of extirpating heathen idolatry from Norway, and introducing the Christian Evangel in its stead.

His transcendent anxiety to achieve this salutary enterprise was all along his grand difficulty and stumbling-block; the heathen opposition to it being also rooted and great.
