THE EASTERN BORDERLANDS was a realm of its own entirely. Bounded very closely to the Emerald sea, the borderlands were rocky cliffs, dry earth, and water-washed coasts. Since the farming fields didn't do well so close to the crashing waves of the sea, the denizens of the coast had to find other ways to make their coin. Other scandalous ways.
Thus, the birth and plight of the Iron Clans.
Some said they were actually descendants of Syverians during the Dark Ages—a fact which summer dwellers disputed greatly. Some others rumored they were traced from the desert tribes across the Carrean sea, the ones that dwelled in the great sands of Irkalla; the people of the arid wastelands. The desert tribes claimed no affiliation to the Iron Clans either.
