There will be flooding too, as the seas rise and surge onto the land. Jormungundr, the Midgard serpent, huge and dangerous, will writhe in its fury, closer and closer to the land. The venom from its fangs will spill into the water, poisoning all the sea life. It will spatter its black poison into the air in a fine spray, killing all the seabirds that breathe it.
There will be no more life in the oceans, where the Midgard serpent writhes. The rotted corpses of fish and of whales, of seals and sea monsters, will wash in the waves.
All who see the brothers Fenrir the wolf and the Midgard serpent, the children of Loki, will know death.
That is the beginning of the end.
The misty sky will split apart, with the sound of children screaming, and the sons of Muspell will ride down from the heavens, led by Surtr, the fire giant, holding high his sword, which burns so brightly no mortal can look upon it. They will ride across the rainbow bridge, across Bifrost, and the rainbow will crumble as they ride, its once-bright colors becoming shades of charcoal and of ash.
There will never be another rainbow.
Cliffs will crumble into the sea.
Loki, who will have escaped from his bonds beneath the earth, will be the helmsman of the ship called Naglfar. This is the biggest ship there will ever have been: it is built of the fingernails of the dead. Naglfar floats upon the flooded seas. The crew looks out and sees only dead things, floating and rotting on the surface of the ocean.
Loki steers the ship, but its captain will be Hrym, leader of the frost giants. The surviving frost giants all follow Hrym, huge and inimical to humanity. They are Hrym’s soldiers in the final battle.
Loki’s troops are the legions of Hel. They are the uneasy dead, the ones who died shameful deaths, who will return to the earth to fight once more as walking corpses, determined to destroy anything that still loves and lives above the earth.
All of them, giants and the dead and the burning sons of Muspell, will travel to the battle plain called Vigrid. Vigrid is huge: three hundred miles across. Fenris Wolf pads his way there also, and the Midgard serpent will navigate the flooded seas until it too is close to Vigrid, then it will writhe up onto the sand and force itself ashore—only its head and the first mile or so of its body. Most of it will remain in the sea.
They will form themselves into battle order: Surtr and the sons of Muspell will be there in flames; the warriors of Hel and Loki will be there from beneath the earth; the frost giants will be there, Hrym’s troops, the mud freezing where they stand. Fenrir will be with them, and the Midgard serpent. The worst enemies that the mind can imagine will be there that day.
Heimdall will have seen all this as it occurs. He sees everything, after all: he is the watchman of the gods. Now, and only now, he acts.
Heimdall will blow the Gjallerhorn, the horn that once was Mimir’s, and he will blow it with all his strength. Asgard shakes with its noise, and it is then that the sleeping gods will wake, and they will reach for their weapons and assemble beneath Yggdrasil, at Urd’s well, to receive the blessing and the counsel of the norns.
Odin will ride the horse Sleipnir to Mimir’s well to ask the head of Mimir for counsel, for himself and for the gods. Mimir’s head will whisper its knowledge of the future to Odin, just as I am telling it to you now.
What Mimir whispers to Odin will give the all-father hope, even when all looks dark.
The great ash tree Yggdrasil, the world-tree, will shake like a leaf in the wind, and the Aesir and with them the Einherjar, all the warriors who died good deaths in battle, will dress for war, and together they will ride out to Vigrid, the final battlefield.
Odin will ride at the head of their company. His armor gleams, and he wears a golden helmet. Thor will ride beside him, Mjollnir in his hand.
They reach the field of battle, and the final battle will begin.
Odin makes straight for Fenrir, the wolf, now grown so huge as to be beyond imagining. The all-father grips Gungnir, his spear, in his fist.
Thor will see that Odin is heading for the great wolf, and Thor will smile, and whip his goats to greater speed, and he will head straight for the Midgard serpent, his hammer in his iron gauntlet.
Frey makes for Surtr, flaming and monstrous. Surtr’s flaming sword is huge and it burns even when it misses. Frey fights hard and well, but he will be the first of the Aesir to fall: his sword and his armor are no match for Surtr’s burning sword. Frey will die missing and regretting the loss of the sword he gave to Skirnir so long ago, for love of Gerd. That sword would have saved him.
The noise of battle will be furious; the Einherjar, Odin’s noble warriors, are locked in pitched battle with the evil dead, Loki’s troops.
The hellhound Garm will growl. He is smaller than Fenrir, but he is still the mightiest and most dangerous of all dogs. He has also escaped his shackles beneath the earth and has returned to rip the throats of the warriors on the earth.
Tyr will stop him, Tyr the one-handed, and they will fight, man and nightmare dog. Tyr fights bravely, but the battle will be the death of both of them. Garm dies with its teeth locked in Tyr’s throat.
