Ragnarok was an event that ocurred roughly 35 years before the start of the campaign, which was destined to destroy Midgard. This destruction was prevented by a band of mortal heroes, as well as help from some celestial figures and dragons.

Rough overview

The giants returned and waged war on the Aesir?. Both parties are now dead, with the exception of Hel?, goddess of death. Midgard? remains intact, thanks largely to the sacrifice of Ivan Kerensky.

Epilogue

as told by the Dungeon Master to the heroes of the previous campaign

Ragnarok, the final, predestined confrontation between the Aesir and the giants, comes to its inevitable conclusion. The giants, Loki, and their legion of demonic allies are defeated, but at a great price; the powerful Norse gods fall in battle one by one. Odin; Thor; Aegir - the deities who have for so long granted their favor and protection to the people of the north are no more. Only Hel, Goddess of Death, who did not participate in the apocalyptic battle, and a handful of lesser deities and demigods, survive.

Three months pass since the final battle. Though the impossible dimensional portals, held open by Loki's will, began to close mere hours after your return to Midgard, a number of lesser demons managed to find their way through. You spend some of your time in the following weeks hunting them down and fending them off. Eventually the sightings and attacks stop, you can never be quite sure that you've gotten them all.

The clerics who have been the spiritual and military leaders of the Varangians and the other tribes lose their divinely granted powers. Some take up worship of the remaining gods, seeing them as inheritors of the Aesir's legacy - Magni and Modi, sons of Thor, gain many followers in this manner. Some, like Aros, retreat into self-imposed exile, wishing to take time to reconsider their place in the world. Sigurd the Wise decides to continue to honor his oath to act as a keeper of knowledge and magical lore, though his own power is diminished almost to nothing.

Prince Alexander has begun the task of rebuilding Novgorod's economy, its trade routes, outposts, and military forces. He worries that with the sudden removal of thedivine spellcasting power which formed much of Novgorod's magical power, the Teutonic peoples to the southwest, though defeated before, will see weakness as an opportunity for attack. And the vast, newly formed swamplands to the south, which now reach the very borders of the principality, are cause for concern as well; more so since before leaving for parts unknown, Aros warned that the planar tear, which allowed him to defeat the Mongol horde so thoroughly, may have brought more than mere seawater from the Realm of the Deep...

You hear from Mzekhar on several occasions, but he speaks in mysterious tones about research to be done and things to be found. Eventually he drops out of sight altogether. Mirek, the ancient pixie, grudgingly informs you that instructions have been left to allow you use of Mzekhar's cavern whenever necessary. You have a lifetime invitation, too, to stay in Novgorod's palace or Sigurd's keep for as long as necessary.

Two weeks after the great battle, you are informed that the rebuilding of the Ivory Citadel is progressing spectacularly, and are invited to a celebratory feast in Hasan's throne room. You are honored as heroes, saviors of the Cherkess people. It's a hell of a party; though it's no Kievan vodka, the drink served has a very distinct kick... and radiates a strange magical aura. Your hosts, with a laugh, tell you to worry less and drink more. Amir thinks he catches Hasan's daughter shooting him a few meaningful glances, though that could be booze...

The next afternoon, after recovering from the hangover of a lifetime, you are summoned once more to the presence of Hasan the Great. He awards each one of you a scroll - a certificate, stamped with the glowing seal of the Cherkess nation - entitling the bearer to 10,000 gp worth of custom magical items crafted at the expense of the royal treasury. "Your heroism, I assure you, is worth much more than this to us - but the recovery from the war will drain our coffers all but dry, and that is all I can give. Rest assured that any favor - any assistance - is always at your disposal."
