Regarding the Daarkin=Four Horsemen.

So i've been reading a few posting saying how each daarkin representes one of the four horsemen of the apocalypse, being: Aatrox=War, Rhaast=Death and Varus=Conquest. With that their is still on horseman left, but which will be used? In some bibles their is famine and others plague. So which is more likely to be? I can see how plague would be rather easy to make, being a mage that does poison damage over time(hopefully NOTHING like singed). But I cant imagine how famine would be implemented.

Also, does anyone else kinda annoyed thats its "Varus" and not "Vaarus"? Unless theres an actually reason for that.
