The next of the Chaos Gods to get themselves featured in the updated factions for Age of Sigmar, Khorne is one of the ones even those outside of strictly GW fans might know of. At least in the form of having probably heard, "Blood for the Blood God!" before.
From the article:
This is it. With the launch of the Dominion box just around the corner, the angriest army in the Mortal Realms bears the honour of being the last faction to get their write-up for the new edition.
If you haven’t read them yet, the 23 other faction articles are already live. Do you want nothing more than to rage-smash every one of those other armies? Then we think you’ll love the Blades of Khorne.
