[Twi]Chronicles of the Impaler: Crisis of Infinite Draculas OOC

[Cracklord]

Well, if we are going for a setting, then that's a good place to start. From a strictly multiversal perspective, this is a subworld of the Urban Fantasy Prime plane (i.e, the world from the 52 that expresses pure and every urban fantasy), that linked with the superhero one after all the catastrophic damage it suffered thanks to the Twipires, explaining why superheroes are suddenly appearing (Isn't that nice?).
But aside from that, there is a lot we can deduce. Shinigami aren't aspects of Death, they are psychopomps. Just like angels aren't aspects of the supreme being, they just work for him. Of course, that's not really important right now, just interesting.
First up, the Librarian conspiracy is probably only the tip of the iceberg, in that what they are actually hiding is the existence of magus's. In Fate/Stay Night, the law for them is effectively 'do whatever you want, don't get caught', and if we add in the factions from Negima (where is Shoveler, by the way?) we get something very like the Librarian conspiracy anyway, if admittedly with considerable more clout.
However, instead of being a big, purposeless, cumbersome organization, like it is in both of those settings, it exists to serve some dark purpose. Furthermore, we have the Brittanian Empire rounding up and putting people who could be assets to their work to a better use within the system. Hence C.C at the start of the manga. And as Draxx noted, perhaps their child-soldier programs are to the same purpose. I suppose we'll have to find out.
For added zest, the Smedry's are all untrained magus's with unrefined talents.

And for the record, Darkblade, nobody plays chess like Lelouch. So rule of cool.
