In the world of Arridon, the saddest ASI self destructs, taking down both itself and all the androids out there – including all the pigeons, because the pigeons are government drones. Makrie, the unique android, survives as she becomes fully human, and walks a world where perhaps libraries will be reborn.

Or maybe it was the Inserendis weapon and not the ASI self destruction? I can’t remember and have to check my notes!
