The Rythons and Yamahiko

Created from the blood of Primordials, infused with elemental power, spawned as a half-kin, the Half-Giants are the decendants of the war machines that powered through the land in the War of Gods and Primordials. After the war, the Half-Giants were lost, devoid of their purpose and went out to seek their own beginnings. The Rythons, and the Yamahiko are what remains of the great giants of yore within Green Crag. Two tribes of different blood, Earth and Fire, were of the first Half-Giant cultures that inhabited the world. After many years of raiding, pillaging, and small skirmishes, the two tribes were forced together with the coming of The Shattering. Both Tribes were forced into a mutual agreement to survive the sinking of their land into the Sea of Fog. Years of tension between the two tribes were put to the test by the new inhabitants of the Isle, straight from the Sea of Fog.
Both tribes survived this perilous journey through the craft of the Yamahitos, and the war cunning of the Rythons. Driving the invaders back to the depths of the fog, the two tribes formed relationships of practicality which created new mingling. Within the first thousand in the Fog, a new nation was born under the banner of the Iron Brink. Helmed by the Kaen Council, the bustling island rose out of the Sea of Fog.
