That night, however, Gudbrand has a most remarkable Dream, or Vision: a Man surrounded by light, bringing great terror with him, who warns Gudbrand against doing battle with Olaf.

"If thou dost, thou and all thy people will fall; wolves will drag away thee and thine; ravens will tear thee in stripes!" And lo, in telling this to Thord Potbelly, a sturdy neighbor of his and henchman in the Thing, it is found that to Thord also has come the self same terrible Apparition! Better propose truce to Olaf (who seems to have these dreadful Ghostly Powers on his side), and the holding of a Thing, to discuss matters between us.

Thing assembles, on a day of heavy rain.

Being all seated, uprises King Olaf, and informs them: "The people of Lesso, Loar, and Vaage, have accepted Christianity, and broken down their idol-houses: they believe now in the True God, who has made heaven and earth, and knows all things;" and sits down again without more words.
"Gudbrand replies, 'We know nothing about him of whom thou speakest.
Dost thou call him God, whom neither thou nor any one else can see?
But we have a God who can be seen every day, although he is not out to-day because the weather is wet; and he will appear to thee terrible and very grand; and I expect that fear will mix with thy very blood when he comes into the Thing.

But since thou sayest thy God is so great, let him make it so that to-morrow we have a cloudy day, but without rain, and then let us meet again.' "The king accordingly returned home to his lodging, taking Gudbrand's son as a hostage; but he gave them a man as hostage in exchange.
