"There's three -- Drachma, to the north, which is allied with Russia; Aerugo to the south, which is allied with Roma; Creta to the West, which is a former British colony.
"Drachma contains more fertile farmland than Amestris but Amestris has more grazing land and ore; at some point Father erected a mountain range along the northern border and Drachma has been trying to cross it ever since. Creta used to be the most powerful presence in the area but its influence has decreased ever since it gained its independence; British campaigns from there are most of the reason for Amestris' national language being English. Aerugo is very small and mostly known for trade; it has access to a large amount of coastline to its south and has a substantial navy. We'll be travelling through it to get to the Eastern Desert, which will take us to Amestris."
