Rossiya Imperii was a country 28 years before Erinaum. But no, Erinaum is more powerful!
Asians, bro. Asian empires grow quickly. It was a huge civilization of almost 2 million people long before Rossiya Imperii. The people of Erinaum now were a minority that lived amongst the people of what was called "Greater Erinaum." They were driven out hundreds of years before the volcanic eruption. The people of "Lesser Erinaum" about 400,000 in number were living in caves and got water from deep in the mountains. The Greater Erinamians were living upon the fertile plain, but had suffered and been poisoned because of the toxic gas and ashes. The people of Lesser Erinaum then struck back when the conditions were right.
The people of Greater Erinaum were warlords that lived in huge stone cities and worshiped and sacrificed to evil gods and idols. There was much corruption. The Lesser Erinamese conquered the suffering Greater Erinaum and captured their huge cities and took over their bustling economy. This is how we became huge so quickly.
The people of Greater Erinaum were not united, but the people, now, of Lesser Erinaum, were. This became modern Erinaum.
