Nice! This really has the feel of an old-fashioned undead "monster" (and I mean that as a positive) and yet the "old man" thing is an original nuance. I take it you were inspired by some muttering curmudgeon you encountered in your travels? :)
Seamlessly fits into an "army" of various undead, sent against PCs, the white-haired, gray-skinned floating spectral head is a great visual.
Finally, knowing that the head was recently someone's grandpa is a macabre touch. "Noooo! Gramps!!"

What exactly does "ghost-flame" do?
This brings up some interesting points.
I'd also add Missing Resources.
For example, our space program would have been immensely complicated by a lack of minable fissionables. Or if Coal or similar concentrated hydrocarbons never developed like they did on earth. No coal or easy oil could easily slow down the march of technology until something else destroys the civilization.

To expand - Coal only came about because for a very long time, there was no organism - bacteria, fungi, etc, that could digest cellulose. So trees would simply not rot when they died. If some bacteria had co-evolved with trees so that trees could not build up that way, you would have no coal. Which, as any CIV player will tell you, is a key resource for Railroads, and therefore most of the industrial techs too. Oil was used well after the coal economy was established.
