Now this feels like a good story that reflects 1490 Euro-Colonialism, specifically the Spanish one. With the multitude of castes (and supposedly castes within castes that really make the number at its height of 29) and a gluttonous pioneer caste / ruling class, it certainly does reflect that reading unironically. Which cruelly sets up a scenario of warfare between raiding / hunting parties and the established ruling class, a bout of extra-national conflict (with some undertones of inner-class conflict between the ruling classes between the nations) is to be expected. And this just humourously plays into the fact that working classes / 29 other castes really can only work as this conflict won't change a thing. So with this period of rest, they take it and begin pondering seriously on where to go. I can definitely see a three-sided war, a war that has an external party invading and a Civil War / Revolution happening as well.
I love your interpretation. This was great fun. Between your battling troops and JD Salinger's gluttonous bananafish in his story, this scenario came to mind.
