In a world of Zahlers and Nenners, one should always assume that one would be stronger than the other. It was the natural way of things; the Zahler will fight in the front lines using their elementalism and increased Wesen reserves, while the Nenner supports said Zahler from the sidelines by crafting weapons and armor that would enhance their partner's fighting prowess. It was the way the world had worked for millennia, unchanged by the passage of time or even the innovations of those that came through it. It was inconceivable that a Nenner would be able to stand toe-to-toe against a Zahler, much less defeat one. In the history of the Matheman Empire, only one person had managed to defeat a Zahler, even more so, a Primzahl; someone that had the caliber to level armies with a wave of their single arm.
And that someone was a Nenner, of all people.
