This may sound like a silly question and I assume that as the Empire, everyone wants a piece of you... but for example, are the Vampires and Orcs (2 random factions used) seen as natural enemies or will they only face off once the humans have been removed from the world?
My lore knowledge is very slim, the main bits ive read are about the Empire as thats who I can relate to easily... but im sure there is more to it. Like the Tomb Kings I believe are based on dead people, would they go for the Vampires?
When the Chaos invasion occurs, do they make a bee-line for the humans? Or will they take on anyone in their path?
