One of the last undefeated fieldmarshall on the Northern Front. 

Most don't know his name, only as Herr Feldmarshal or Northern Butcher. A fiery man who once had prestigious estate and a happy family. Now, only his grand estate remained. His son, his younger, better-in-anyways self,  killed in action by Blütnacht. His wife died from heartbreak and relieved from her long-ill existence by a common cold.

August von Mackenson was a man of war but now, there is no more war.
