Fun facts: Does not occur naturally in any significant amount. Created synthetically in nuclear reactors. It glows faintly in the dark and has been used in luminous watch dials and space instruments. Named after Prometheus, the mythic fire-bringer who gave knowledge (and trouble) to humanity.

Great for: Mythology fans, space engineers, rare-element aficionados, and anyone who plays with fire—metaphorically or otherwise.
