Just wondered with the Emperors Children battle cry"Children of the Emperor, Death to his foes" do you think they would have changed it when they turned tratior?
Nope, we kept it like we kept the Imperial Eagles on our armour.
At first it served to confuse the lackeys of the False Emperor, and to some extent still does...but more pleasingly for Slaanesh we have kept it, and the Imperial Eagles because it infuriates the weakling Imperials.
The most likely changed it to something like -
"I'm reet horny, me... come get some!" :lol:
I'm going to move this over to the EC section because it doesn't have a definitive answer.
