Dear brain: You must, in fact, either make weapons for Cheliax, or not make weapons for Cheliax. To take neither of these options is not, in fact, among your options. So you should decide which these two things is better, and then do that thing, and then not feel bad about it.
If that argument doesn't sound appealing, is it because there is some additional thought Keltham is supposed to think, to weigh, before deciding? Please exhibit it, brain; or make a gesture in its general direction. Or throw up a tiny note of discordance or something.
