Proeliator Latro is the ruler of Bellum, one of the nine Galenian colony worlds. And he’s a really, really, really bad guy.
Oh, sure, he seems innocuous enough in chapter one, perhaps even a bit pompous and stuffy. That’s his diplomatic persona, though. His true colors are shown when he pops back up in chapter 15, in which he beats a slave to death out of anger.
And he only gets worse.
