When the gods have ridden through the southern Hel-gate, there lie before them magnificent regions over which Urd in particular rules, and which together with Mimer's domain constitute the realms of bliss in the lower world with abodes for departed children and women, and for men who were not chosen on the field of battle. Rivers flowing from Hvergelmer flow through Urd's domain after they have traversed Mimer's realm. The way leads the gods to the fountain of the norns, which waters the southern root of the world-tree, and over which Ygdrasil's lower branches spread their ever-green leaves, shading the gold-clad fountain, where swans swim and whose waters give the whitest colour to everything that comes in contact therewith. In the vicinity of this fountain are the thingstead with judgment-seats, a tribunal, and benches for the hosts of people who daily arrive to be blessed or damned.
These hosts enter through the Hel-gate of the east. They traverse deep and dark valleys, and come to a thorn-grown plain against whose pricks Hel-shoes protect those who were merciful in their life on earth, and thence to the river mixed with blood, which in its eddies whirls weapons and must be waded over by the wicked, but can be crossed by the good on the drift-wood which floats on the river. When this river is crossed the way of the dead leads southward to the thingstead of the gods.
Further up there is a golden bridge across the river to the glorious realm where Mimer's holt and the glittering halls are situated, in which Balder and the ásmegir await the regeneration. Many streams come from Hvergelmer, among them Leiptr, on whose waters holy oaths are taken, and cast their coils around these protected places, whence sorrow, aging, and death are banished. The halls are situated in the eastern part of Mimer's realm in the domain of the elf of the rosy dawn, for he is their watchman.
Further down in Mimer's land and under the middle root of the world-tree is the well of creative force and of inspiration, and near it are Mimer's own golden halls.
Through this middle part of the lower world goes from west to east the road which Nat, Dag, Sol, and Mane travel from Billing's domain to Delling's. When the mother Nat whose car is drawn by Hrimfaxi makes her entrance through the western Hel-gate, darkness is diffused along her course over the regions of bliss and accompanies her chariot to the north, where the hall of Sindre, the great artist, is located, and toward the Nida mountains, at whose southern foot Nat takes her rest in her own home. Then those who dwell in the northern regions of Jormungrund retire to rest (Forspjallsljod, 25); but on the outer rim of Midgard there is life and activity, for there Dag's and Sol's cars then diffuse light and splendour on land and sea. The hall of Sindre's race has a special peculiarity. It is, as shall be shown below, the prototype of "the sleeping castle" mentioned in the sagas of the middle ages.
Over the Nida mountains and the lands beyond them we find Ygdrasil's third root, watered by the Hvergelmer fountain, the mother of all waters. The Nida mountains constitute Jormungrund's great watershed, from which rivers rush down to the south and to the north. In Hvergelmer's fountain and above it the world-mill is built through whose mill-stone eye water rushes up and down, causing the maelstrom and ebb and flood tide, and scattering the meal of the mill over the bottom of the sea. Nine giantesses march along the outer edge of the world pushing the mill-handle before them, while the mill and the starry heavens at the same time are revolved.
Where the Elivagar rivers rise out of Hvergelmer, and on the southern strand of the mythic Gandvik, is found a region which, after one of its inhabitants, is called Ide's pasture (setr—Younger Edda, i. 292). Here dwell warriors of mixed elf and giant blood (see the treatise on the Ivalde race), who received from the gods the task of being a guard of protection against the neighbouring giant-world.
Farther toward the north rise the Nida mountains and form the steep wall which constitutes Nifelhel's southern boundary. In this wall are the Na-gates, through which the damned when they have died their second death are brought into the realm of torture, whose ruler is Leikinn. Nifelheim is inhabited by the spirits of the primeval giants, by the spirits of disease, and by giants who have fallen in conflict with the gods. Under Nifelhel extend the enormous caves in which the various kinds of criminals are tortured. In one of these caves is the torture hall of the Nastrands. Outside of its northern door is a grotto guarded by swarthy elves. The door opens to Armsvartner's sea, over which eternal darkness broods. In this sea lies the Lyngve-holm, within whose jurisdiction Loke, Fenrer, and "Muspel's sons" are fettered. Somewhere in the same region Bifrost descends to its well fortified northern bridge-head. The citadel is called Himinbjörg, "the defence or rampart of heaven." Its chieftain is Heimdal.
While Bifrost's arch stands in a direction from north to south, the way on which Mane and Sol travel across the heavens goes from east to west. Mane's way is below Asgard.
