Until that time Sindre-Dvalin and Mimer's six other sons slumber in that golden hall which stands toward the north in the lower world, on Mimer's fields. Nat, their sister, dwells in the same region, and shrouds the chambers of those slumbering in darkness. Standing toward the north beneath the Nida mountains, the hall is near Hvergelmer's fountain, which causes the famous maelstrom. As sons of Mimer, the great smith of antiquity, the seven brothers were themselves great smiths of antiquity, who, during the first happy epoch, gave to the gods and to nature the most beautiful treasures (Mjolner, Brisingamen, Slidrugtanne, Draupner). The hall where they now rest is also a treasure-chamber, which preserves a number of splendid products of their skill as smiths, and among these are weapons, too large to be wielded by human hands, but intended to be employed by the brothers themselves when Ragnarok is at hand and the great decisive conflict comes between the powers of good and of evil. The seven sleepers are there clad in splendid mantles of another cut than those common among men. Certain mortals have had the privilege of seeing the realms of the lower world and of inspecting the hall where the seven brothers have their abode. But whoever ventured to touch their treasures, or was allured by the splendour of their mantles to attempt to secure any of them, was punished by the drooping and withering of his limbs.
When Ragnarok is at hand, the aged and abused world-tree trembles, and Heimdal's trumpet, until then kept in the deepest shade of the tree, is once more in the hand of the god, and at a world-piercing blast from this trumpet Mimer's seven sons start up from their sleep and arm themselves to take part in the last conflict. This is to end with the victory of the good; the world-tree will grow green again and flourish under the care of its former keepers; "all evil shall then cease, and Balder shall come back." The Teutonic myth in regard to the seven sleepers is thus most intimately connected with the myth concerning the return of the dead Balder and of the other dead men from the lower world, with the idea of resurrection and the regeneration of the world. It forms an integral part of the great epic of Teutonic mythology, and could not be spared. If the world-tree is to age during the historical epoch, and if the present period of time is to progress toward ruin, then this must have its epic cause in the fact that the keepers of the chief root of the tree were severed by the course of events from their important occupation. Therefore Mimer dies; therefore his sons sink into the sleep of ages. But it is necessary that they should wake and resume their occupation, for there is to be a regeneration, and the world-tree is to bloom with new freshness.
