Innovation of Necessity

Craft a narrative about a society facing a daunting crisis that gets resolved by an unexpected innovation.

This prompt explores the idea of ingenuity born out of necessity. How does this society respond to the crisis at hand? Who is the person or group that comes up with the innovation and how are they affected by it? Does the innovation address only the crisis or does it change other aspects of the society as well? Themes of endurance, collective problem solving and societal transformation could be explored here.
