The Valkyries ("chosers of the slain") are beautiful young women, mounted upon winged horses and armed with helmets and spears. Odin needs many brave warriors for the oncoming battle of Ragnarok, and the Valkyries scout the battlefields to choose the bravest of those who have been slain. They escort these heroes, called the Einherjar to Valhalla, Odin's hall.

The chief divinity of the Norse pantheon, the foremost of the Aesir. Odin is a son of Bor and Bestla. He is called Alfadir, Allfather, for he is indeed father of the gods. With Frigg he is the father of Balder, Hod, and Hermod. He fathered Thor on the goddess Jord; and the giantess Grid became the mother of Vidar.

Odin is a god of war and death, but also the god of poetry and wisdom. He hung for nine days, pierced by his own spear, on the world tree. Here he learned nine powerful songs, and eighteen runes. Odin can make the dead speak to question the wisest amongst them. His hall in Asgard is Valaskjalf ("shelf of the slain") where his throne Hlidskjalf is located. From this throne he observes all that happens in the nine worlds. The tidings are brought to him by his two raven Huginn and Muninn. He also resides in Valhalla, where the slain warriors are taken.

Odin's attributes are the spear Gungnir, which never misses its target, the ring Draupnir, from which every ninth night eight new rings appear, and his eight-footed steed Sleipnir. He is accompanied by the wolves Freki and Geri, to whom he gives his food for he himself consumes nothing but wine. Odin has only one eye, which blazes like the sun. His other eye he traded for a drink from the Well of Wisdom, and gained immense knowledge.

On the day of the final battle, Odin will be killed by the wolf Fenrir. He is also called Othinn, Wodan and Wotan.

Valhalla, Hall of the Slain, in Norse mythology is the hall presided over by Odin. This vast hall has five hundred and forty doors. The rafters are spears, the hall is roofed with shields and breast-plates litter the benches. A wolf guards the western door and an eagle hovers over it. It is here that the Valkyries, Odin's messengers and spirits of war, bring the heroes that died on the battle fields. These heroes, the Einherjar, are prepared in Valhalla for the oncoming battle of Ragnarok. When the battle commences, eight hundred warriors will march shoulder to shoulder out of each door.

Ragnarok ("Doom of the Gods"), also called Gotterdammerung, means the end of the cosmos in Norse mythology. It will be preceded by Fimbulvetr, the winter of winters. Three such winters will follow each other with no summers in between. Conflicts and feuds will break out, even between families, and all moral will disappear. This is the beginning of the end.

The wolf Skoll will finally devour the sun, and his brother Hati will eat the moon, plunging the earth in darkness. The stars will vanish from the sky. The cock Fjalar will crow to the giants and the golden cock Gullinkambi will crow to the gods. A third cock will raise the dead.

Earthquakes will shudder the earth, and every bond and fetter will burst, freeing the terrible wolf Fenrir. The sea will rear up because Jormungand, the Midgard Serpent, is twisting and writhing in fury, making his way toward the land. With every breath, Jormungand will stain to soil and the sky with his poison. The waves caused by the serpent's emerging will set free the ship Naglfar, and with the giant Hymir as their commander, the giants will sail towards the battlefield. From the realm of the dead a second ship will set sail, and this ship carries the inhabitants of the hell, with Loki as their helmsman. The fire giants, led by the giant Surt, will leave Muspell in the south to join against the gods. Surt, carrying a sword that blazes like the sun itself, will scorch the earth.

Meanwhile, Heimdall will sound his horn, calling Odin's sons and heroes to the battlefield. From all the corners of the world, gods, giants, dwarves, demons and elves will ride towards the huge plain of Vigrid ("battle shaker") were the last battle will be fought. Odin will engage Fenrir in battle, and Thor will attack Jormungand. Thor will be victorious, but the serpent's poison will gradually kill the god of thunder. Surt will seek out the swordless Freyr, who will quickly succumb to the giant. The one-handed Tyr will fight the monstrous hound Garm and they will kill each other. Loki and Heimdall, age-old enemies, will meet for a final time, and neither will survive their encounter. The fight between Odin and Fenrir will rage for a long time, but finally Fenrir will seize Odin, and swallow him. Odin's son Vidar will at once leap towards the wolf, and kill him with his bear hands, ripping the wolf's jaws apart.

Then Surt will fling fire in every direction. The nine worlds will burn, and friends and foes alike will perish. The earth will sink into the sea.

After the destruction, a new and idyllic world will arise from the sea and this new earth is filled with abundant supplies. Some of the gods will survive, others will be reborn. Wickedness and misery will no longer exist and gods and men will live happily together. The descendants of Lif and Liftrasir will inhabit this earth.

The Einherjar are the heroes who have died with great bravery on the battle fields. These heroes are prepared in Valhalla for the oncoming battle of Ragnarok. In the morning they are woken by the crowing of the cock Gullinkambi ("golden comb"). During the day they train and fight, until they cut each other to pieces. At night they feast at Odin's side and their wounds are miraculously healed.

On the day of Ragnarok, the bravest of the Einherjar will march with Odin to battle the frost giants, the enemies of the gods.
