Nothing is known about Schonhuber's background.
Schonhuber is a sturdy man with short blonde hair.
He is responsible, outspoken but hasty and stubborn, rarely taking advice from others. Due to the fact that he has been guarding a rather peaceful village, he is low on guard and has a poor judgement of a battle's situation. Later on, however, he shows his bravery and altruism, offering to sacrifice himself to secure an escape route for Bernd Baltzar, Prince August and the others.
Schonhuber has yet any but the standard set of skills of a Weißen soldier.
Hartmann is Schonhuber's subordinate. They seem to share a trusting and relatively good superior-subordinate relationship.
