Vengeance is a Dish Best Served Chilly
It had been some time since Wolfgang was first taken into custody after he had assaulted an Imperial Prince. During this time, while Wolfgang awaited his trial, he was kept within one of many of Germany's labor camps, where the nation housed its hardened criminals. German Justice was harsh, as it was designed with a single purpose in mind. To punish criminals, and to deter future crimes via intimidation.
No prisoner was exempt from the backbreaking labor they would be forced to endure day in and day out, and it was because of this that especially pampered noblemen like Wolfgang typically died from attrition long before their sentence was compete. Luckily Wolfgang had survived his treatment, though he had lost much of his youthful vigor.
