He got to the frontlines, yes. But what he does there? Instead just trying to “survive the hell” he chases the opportunities to get… promoted?
I don’t think Caldy’s death was the intention here. Think about it more like a booby prize, a form of fobbing him off if you will “Yeah, we promissed, but hey look, here’s a nice place for you too, a litttle higher in hierarchy than a pit fighter. With some more stuff to kill… We good? Good.”.
BTW It is Deande’s opinion Caldy had a better odds of surviving as a pit fighter. She also speculates if this was about satiating his thirst for blood. Just because the Jennerit elites didn’t want to share their “noble blood” with Kameesian doesn’t mean they’d act totally unjust. This is Rendain’s turf. Social advancement through military is a common theme in militarized societies. Even Caldy himself didn’t complain much about “the consignment”.
I’ve mentioned about Rendain, above. It’s also his work to act against commmons and tradition. He’d award Caldy sustainment, as a punishment, yes, but also against the tradition and the elites’ opinion. Doesn’t this make Caldy’s situation doubly ironic?
