Giant's Creation from Blood and Bone

Giants tell a different tale of the earliest eras. Life sprang up in the center of the Void where rime met flame, melting and boiling. This was Aurgelmir, the first and greatest giant, from whose body both the earth and sky were crafted. Creatures sprang from Aurgelmir like branches on an oak, among them the first giants and the eldest of the gods, who fought on dragonback against the giants. The two groups warred, and when Aurgelmir sided with his giant kin, the gods slew him.
The giants have never forgotten this murder. Since that day they’ve nursed a grudge and hope one day to see the gods’ dominion ended and their forefather avenged. Loki always stands ready to remind them of the offense, and Boreas whispers of the glories of battle. Most of the dark gods find the giants’ grudges most convenient to this day.
The gods, meanwhile, fashioned the world from Aurgelmir’s corpse. His bones became the earth and his blood flowed out to fill the rivers and seas. From his teeth they fashioned mountains and his hollow skull became the sky. With giants cowed by the cleaving of Aurgelmir, the gods explored their new-forged world and soon they fell to strife among themselves.
The gods of nature and the gods of passion and glory formed factions and fought for dominion over their new realm of Midgard, and Creation trembled with the blows they struck. Eventually canny Wotan, always wise and victorious, brokered a truce. The gods exchanged hostages and peace descended once more.
Smaller races took their place in the world, and the gods watched. As far as the giants are concerned, they are still the true inheritors of the world and its treasures.
