After the fall of Egypt, and the destruction of the Babylion Civilisation at the hands of the Olympians, Greece reigns supreme at the heart of the world. However, it is anything but united.
The Greeks are overseen by the Twelve Olympians, the mighty gods of the Greeks, and the nation is split into twelve seperate kingdoms, each ruled by one of the Twelve Olympians. These kingdoms are in a constant state of flux, growing and shrinking as the Olympians’ wage war on eachother, snatching away land or watching it fall between their fingers.
Often, those that see success in the Pantheon are those whose empires see success. Empowered by a high placing in the Pantheon, the Olympians in turn empower their subjects with immense power, and this is a deciding factor in many conflicts.
The Greek world may be in constantly changing, but the system enforced by Zeus sees the old maps dusted and smoothed out, as a newly triumphant god wrestles back what was stolen from them, and the cycle begins anew.
