Planet Eretre had four continents and thirteen city-states. While the number might seem small, it shouldn't be underestimated as planet Eretre was about 1.5 times the size of Earth, or fifty percent (50%) larger. Excluding Digress city-state, which was the smallest, every other city-state controlled land at least twice the size of a nation on Earth. Some of the stronger city-states controlled more land than this.
Apart from the civilised area, there were large undeveloped plots of lands that either turned into wastelands or habitats for desolate beasts and abominations.
Of the thirteen city-states, the most reputable ones were Java city-state, which was one of the most famous trading hubs on the planet; Paros city-state, which had the reputed Lester family and the sub-branch of the powerful Lin family from Mandora planet; and another city-state. As for Baylands city-state, it was at the upper middle level of the rankings, sixth place to be exact.
