A number of peaceful Aronai clans lived in the southeast of the Commonwealth near the Setic Empire. They had been working together closely and adopted many civilization traits from their Segai neighbors. Eventually they wanted to break with the old Aronai ways and only keep the core of what was Aronai, and grow into real strength, as they saw it. In 2829 they broke away from the Commonwealth and declared themselves independent as the kingdom of Atrogia. A great number of Aronai clans were furious and took off to war. The Council of Clan Lords could not come to an agreement on the matter, so only those who wanted to punish the oath breakers were free to fight. The Atrogians were quite prepared for the response and defended their borders with success, even as the attacks went on for decades. It took several centuries before normal relationships were established, but the Atrogians were not dependent on the Commonwealth and gained strong support from the Segai neighbors. Neighboring clans like Iroir and Saibair still do raids at times.
