Some time ago I had the idea for a Greek-analogue empire in a satellite style.
This is the eastern part of the continent of Eudorea (sizewise: Norway to Italy in N-S direction), where the Chyroneian Hegemony has risen to power over the last 50 years. First it had conquered weaker neighbors and then smashed a coalition of those and then attacked and seized the northern provinces of the Empire of Satramond.
