ペロポネソス同盟
Keld has declared war on Jamuraa in order to reclaim 'hero's blood', known also as tufa, which is a type of fossil fuel to run great machines. The city-states of Jamuraa form the Kipamu League and then repulse the invaders. The war bears a striking similarity to the Peloponnesian War between the Athenian Empire and the Peloponnesian League.
