If it's been with us all through history, I guess the further back you go, the more likely it is that you will have seen someone be crushed by the hand. And global travel? That's the foundation for a persistent global mythology that'd probably dominate our storytelling for a while. I don't know what all happens between then and the point where we have satellites that track the hand all the time, but I bet there's potential for a novel. Or an anime. Or at least a comic.
