Whereas Aregrionno consists of different vals that started out as part of a whole that got more independence over time, Helladris has always consisted of three distinct domains; Amarillo in the north, Azul at the heart, and Morado in the west.
These three regions share many geographical and cultural commonalities, which has led to them uniting under a shared banner (the Helladrian one) whenever practical, for matters such as diplomacy, trade, and defense.
In a way, this just required putting another layer on top of the already existing representative democracy.
This alliance has proven highly effective; when Dorion declared independence in 632 5E, no other country or nation was so quick with sending food, medicine, and supplies to the fledgling nation as united Helladris.
When Dorwin crossed the eastern border in retaliation two months later, the response of Helladris could not have been more unified, either; Dorwin military commanders reported a "gruesome, asymmetric battle in which the sudden crack of thunder from treelines and rooftops shredded our men by the handful".
