Ah the Equestrians. A recently sanctioned race of xenos under the direction of Primarch Roboute Guilliman has come under attack by chaos forces.
 
Their rumored “Elements of Harmony” has been reported to have cleansing effects on chaos entities and, if possible, could be used to keep the Eye of Terror in check. Thus it is imperative we protect this potential weapon from falling into the wretched tendrils of the ruinous powers.
 
Normally the Imperium would crush such vile xenos races and take their technologies for ourselves, but these are strange times, and we already have an accord with the Ynnari Eldar.
 
Open alliances with xenos? Emperor forgive us if our path has strayed.

Oooh, I think I see what you mean.

I think the loyalists are the ponies and the Chaos marines are Human. The marine on the far right firing a storm bolter clearly has a hoof.

Not to be that guy, but where does pony come into this? Unless there’s some context I’m missing out on, which is certainly possible, I can’t quite see anything here that would tie into MLP.

Yeah this looks pretty heretical.
