The long war between good and evil, light and darkness, order and discord, the Asir and the Jotuns, was at last to reach a fatal crisis and end in one universal battle, called Ragnarokur, or the "Twilight of the Gods," whose result would be the total destruction of the present creation. Portentous inklings of this dread encounter were abroad among all beings. A shuddering anticipation of it sat in a lowering frown of shadow on the brows of the deities. In preparation for Ragnarokur, both parties anxiously secured all the allies they could. Odin therefore joyously welcomes every valiant warrior to Valhalla, as a recruit for his hosts on that day when Fenris shall break loose. When Hakon Jarl fell, the Valkyrs shouted, "Now does the force of the gods grow stronger when they have brought Hakon to their home." A Skald makes Odin say, on the death of King Eirilc Blood Axe, as an excuse for permitting such a hero to be slain, "Our lot is uncertain: the gray wolf gazes on the host of the gods;" that is, we shall need help at Ragnarokur. But as all the brave and magnanimous champions received to Valhalla were enlisted on the side of the Asir, so all the miserable cowards, invalids, and wretches doomed to Hela's house would fight for the Jotuns. From day to day the opposed armies, above and below, increase in numbers. Some grow impatient, some tremble. When Balder dies, and the ship Nagelfra is completed, the hour of infinite suspense will strike. Nagelfra is a vessel for the conveyance of the hosts of frost giants to the battle. It is to be built of dead men's nails: therefore no one should die with unpaired nails, for if he does he 7 Pigott, pp. 137, 138. 8 The Voluspa, strophes 34, 35. furnishes materials for the construction of that ship which men and gods wish to have finished as late as possible.9
