In homebrewed PbtA-based Wuxia-game:
Found cure for magical plague...
As a sidenote, we as players know exactly how the plague came to be, as one of our other groups of characters in the campaign dealt with it at the source. but it was intentionally spread, so it ended up way further away, so another gorup had to deal with at as well. And that group now knows that it was intentionally spread. Will we encounter it again? Quite likely.
