(werner pronounces his own name as verner verman, pun on vermin)

Werner is a supporting role. He is a mouse. He's as stubborn as Kahl, maybe more. Unlike Kahl, he wears his heart on his sleeve, maybe to a fault. And his time in the military taught him how important hard work is, so he is endlessly dedicated no matter how much the killing game beats him down. But even he wonders how long he can keep going.

German is Werner's first language. He will sometimes instinctively speak it a bit, and has, at minimum, a slight accent. It changes in intensity depending on his emotions. It's highly recommended to know at least some German for this role. 

Voice headcanon is any otherwise, just make sure of the above.
