Hmm, I'm interested, but I've got a few questions. 

What do you mean by "cardinal beings" it's quite a broad aspect. Like, hmm, which branch of mythology are you referring to?

Magical Capabilities, say, is it elemental, or will it compromise of anything within one's imagination? 

Setting-wise, is it safe to assume it's futuristic? In a sense that when they try to "reclaim" the world they left, and all, their mode of defense/attack would be rifles, guns, and the like? Or some sort of mix between magical enchanted scythes, swords, bows, and you know, so on.
