A Dark day hits the Reich. All men have limited lives, and the Kaiser was no exception. A insane heretic decided to assassinate the Kaiser in a truly brutal manner. The Assassin would have been quickly killed by the guards, if the crowds hadn't killed him first. It had later been determined to be a cyborg drone created by the Droids, and the body was quickly "destroyed"(OCC: I.e. sent to top secret research lab for study. Those implants could prove useful in messing up robot assaults and defenses.), though nethier was announced.
The crown prince Fredrick Von Prussia proceeded to declare he would take the throne as the legitamite heir to the throne, but his claim is contested. The new Kaiser only had the support of the Clergy, but not the Military and the secret third pillar, Prussian Industries, which was by now the only company at all in Prussia...
The New Kaiser was a holy man, being the new head of the religion and according to the clegry, has received the divine powers of his father.
The Military has been split. Hans Georg Otto Hermann Fegelein the second is trying to impose a military dictatorship, with him as Its Leader. Rommel has declared he serves Prussia, and will not partake in the struggle. Someone needs to command the military against the droids. (good thing he decided to not send Fegelin into the battle...keeps him out of the way.) All sides respect Rommel for his choice. Everyone knows he would win in that case...
Prussia Industries is lead by Jodl Himmler, literally the richest man outside the royal family. He wished to complete the monopoly on the economy By becoming the government. It does not need saying twice, but a Prussia drivin by profit would be even more dangerous and aggressive then the current regime...and any military dictatorship as well.
There are also rumors that communist revolutionaries are planing at making a move as well...though because all weapons are made by Prussia Industries they were stopped within hours.
Kaiser is killed by remote controlled human by drones. Power struggle starts. Invasions continue as planned WE will retake our territory
