Plot Hook: When Pigs Shine (Patreon)

Something strange happens almost every spring, and a curious scholar wants to know why. He's willing to pay a lot of gold for evidence that explains the thing.

This was inspired a trio of words that were given to me at a convention: singularity, pigs, and brightness.

In weather, a singularity is something unusual that happens on a regular basis, possibly happening only for a single day.
