Cream of the crop.. named after expendable cannon fodder..
I mean it sounds badass but the reference one would draw on makes no sense, nor could it since Gallia seems bent on being a nation of essentially xenophobes; any other ethnic groups built in seem to have been assimilated into "Gallic" proper (or pushed aside, as in my NS idea). While I'd imagine it could be bent a bit given the lack of explanations on a lot of things, the overall trend of this xenophobia is apparent.
Still, it's a nice story and all that, though it looks more like something that would be built into the GRN, like an unstoppable "Royal Palace Guard" or something of the sort.
