For everyone that likes Warhammer 40k Tabletop and Dawn of War Games or anything to do with Warhammer 40K.
Recently revealed on the Warhammer Community site, this is the cover art for the upcoming Horus Heresy novel detailing the Beta-Garmon campaign, a war so huge that it completely destroyed Titan Legions on both sides of the conflict and basically is the main reason the Imperium has a lot less Titans post-Heresy. Art by Neil Roberts.
It's not often you get to see multiple Imperators in one shot.
I'm guessing that's Dies Irae.
The Dies Irae marches in the Legio Mortis and is thus colored black, red and gold. Forge World named that green-and-red legio somewhere recently, but I can't recall the name.
oh yes, it's Legio Solaria, the Imperial Hunters!
bringing out the big guns...literally.
So basically the Kursk of titan battles during the Heresy.
in a nut shell pretty much yea.
The writers probably thought, "Tallarn was cool, but how could we make it even more overkill?"
