Whoah! Blood Red! Blood Red!
For you The Crimson Ghosts fans out there in the audience.
Games Workshop is certainly getting into the spirit with a whole bunch of new pre-orders they're taking for Khorne units over in their webshop. There's also a new Codex, so that might have something to do with it.
Like I mentioned, as you can see there, there's a lot of new stuff they've got going on. Certainly plenty to expand your chaotic Age of Sigmar army to fill your board with red (and your opponent's side, too, as you hack them all to pieces, of course).
