I wonder if the concept of threshecutioners (and by extension cavalreapers?) as grain-flayer/soldier hybrids could also act as a reference to the fact that grist, literally speaking, is grain separated from its husk? Like Karkat is being trained to thresh his enemies into grist the same way Alternian society teaches server skills through architecture…
#implying I suppose that Alternians systematically use the remains of their enemies as crafting materials?#which would kind of explain everything about their technology… right down to the frequent use of ‘husks’#works doubly for cavalreapers who are presumably involved in monster creation if we take fiduspawn at face value…
there’s something about the synonymity between blood/genetic material and grist in this, too, but it’s an incomplete thought
