Kampfer

The Kämpfers are an elite infantry units that form the Vallum Emperor's household troops, bodyguards and private army. The corps was established during the reign of Arthur The Expander. (2689-2712).

Early History
They began as an elite corps of slaves made up of kidnapped Machina who were forced to convert to Tohvokhiism(the official religion in Vallum) through strict discipline and order. Unlike typical slaves, they were paid regular salaries. Forbidden to marry or engage in trade, their complete loyalty to the Emperor was expected. The Kampfer units were often known as the elite forces due to this

Modern History after Arthur the Expander
After Arthur's reign, the Kämpers were turned into the elite guard of the empire's guard and a private army, the usage of Machina was forbidden and they instead began to target Majirit people throughout the empire, although this was considered to be against Tohovok's word to some.

By the start of 5442, due to the dramatic increase in the size of the android forces, the Kämpfer's strict recruitment policy was relaxed. Citizens were conscripted into the corps in order to inflate their ranks. Consequently, many rich citizens began adopting slave children into their families to prevent their children from being conscripted.
