Excellent, this is sweet, it has a varied tone to the write up and a great deal of depth achieved with a conservation of language. I could see using this as pit stop in Noir-ish style mystery. The PC may need some knowledge that only a man of the march has and thus have to find him and break his stride at least briefly-maybe wait for eclipse or something.
Once again we learn that the ticket to immortality is not worth the price of admission. Indeed the only thing meant to live forever seems to a be repackaging of that old chestnut.

But it seems to be a novel mechanism, and that is hard to come up with since this story has been told from the angry and scared man-child in Gilgamesh to the ennui ridden vampires (the ones that didn't date high school students).
