The unification campaign-turned-cataclysmic war that ravaged Nasza Ziemia for over 1500 years. Beginning as an attempt by the Giants to purge the lands of the corrupted magics sown by the Dragon Tyrant, it became a plane-wide occupation and invasion, led most prominently by the Titan King Vanir, the Storm-Blooded.
Giant's War: 3047-4011
After the Dragon Tyrant fled the plane, scores of Dragons sought to take their place. Refusing to see another oppressor upon the hated throne, the United Giants declared war on these Draconic Usurpers. The fighting spanned every continent, scorching lands, shattering mountains, and turning entire seas red with blood. After 964 years, the Giants emerged victorious. The Draconic Usurpers that remained were imprisoned, their fires used to light the furnaces from which the Giants forged their weapons & armor.
Titanfall: 4037-4560
Once the war was over, the Giants sought to rebuild & unify Nasza Ziemia once again, as it had been before the Dragon Tyrant's cruelty. Runesmiths were sent to every corner of the plane to eradicate all traces of the Dark Age. Unfortunately, they discovered many new civilizations were already built atop the ruins. While the Giants and Dragons had waged war, the rest of the plane had sought to start over wherever they could. For those too young to remember the days before the Dragon Tyrant's oppression, this was the only world they had ever known. Unable to accept a world tainted by the evils that had tormented them so long, the Giants declared their intent to return the plane to its original splendor, no matter what stood in their way. Their forges of dragonfire were lit, and war waged once again. A war blinded by righteousness & hubris that quickly turned from unification to the very oppression they had sought to eradicate.
The turning point came with the death of Aisling, Goddess of the Elves. Her sacrifice inspired the Immortal Lands in driving the Giants off the continent. The death of one of the New Gods also served as the turning point for Calamity, who finally freed the Old Gods they'd sealed away for millennia. With the Gods' return, the Giants were forced back to the very edge of the plane, the icy tundra of Fimblvintr.
