The Nail is clearly an insanely powerful magical artifact, able to amplify creatures of darkness's innate powers far beyond their normal limits. The fear effect the normal revenants we see in Dragonwatch give off is nothing compared to that of the one from Fablehaven, and Ephira and Kurisock would never have been able to create the Shadow Plague without it. Heck, the thing literally seemed to have a will of its own, digging itself into the dirt and giving its remaining power to Seth. So what was it?

Really weird idea I came up with while plotting a fanfic, but I think it has potential. I'd imagine these "demigods" are regular humans infused with demigod blood through some dank Ancient Greek magic or outright created from cultured blood through ritual. I think it could be a fun way to explore the magical side of the Camp-Half-Blood world. What do people think?
