...Not nuclear war, I'm only even vaguely familiar with the term. The Astral War left much of the planet a wreck during my mortal life - outright war between and against the gods, particularly the god of fire, I can summarize the details but it will take a while.

And then on the far end of my life there was the Night [you can hear the capital] which lasted for ten years and I imagine devastated most of the planet, but I didn't see the end of that, technically.
