no, THIS is heresy

How is the Emprah heresy?

Because there is only one emperor.

Chaplains would be hard, because they wouldn't converse with humans.

Comissars seem like the way to go. But then there's the problem of their methods...

If somebody provides me with the armor, I'll do it, I am already 6'4. with some lifts and those thick ass space marine boots I could probably pass for a short marine.

Or just have a bunch of space marines and chaos marines stand in front of them and just stare..... menacingly.... Then rip each other to blood pieces with chainswords and.... "accidentally" rampaging through the WBC with a blood crazed chaos marine.

Yes, yes it is. It's captain Titus from the Warhammer 40K:Space Marine game

Some guy at deviantart merged Titus from the cover of the game with a Deathwing promotion picture if I remember correctly

err no i made this at school for the hell of it.

I wonder if anyone's ever written out an Imperial prayerbook.

There are several pages of litanies in the back of the Uplifting Primer

Throne dammit, I knew I should have bought one of those. Do you know if they're also in the Imperial Infantryman's Handbook?

That's what I have/meant. sorry for any confusion.

Perfect.

lol whats even batter is that in the bathroom of my local GW they have some printed out and framed. such as the litany of unloading.

What about if one guy dresses up as Horus and punches the guy dressed up as the Emprah, and starts to convert them to chaos

Oh man, that would be great, can you imagine preaching Slaanesh in front of westboro? I think they might actually become convinced that their souls were damaged for having heard you.
