It was triggered when a mathematician discovered a new series of numbers. Like negative, irrational and imaginary numbers, "commotic" numbers seem like purely mental constructions but turn out to describe the real world. Unlike the others, expressions written with magical or "commotic" numbers also directly affect the world, by changing the relationships between things and places.

For eight hundred years, society has been painfully rebuilding, aided by magicians of mathematics.
