Absolutely, I don't blame the Imperial Fists for being so rigorous (though the Kyras stuff was I believe much later).

yeah, by the way I was wondering, what happens if a human breathes ork spores. I tried to look it up but you know the internet, looking for answers can be like a needle in a haystack. also what's your opinion on dawn of war 3 cause I've heard a lot of hate for it

I'm not actually sure about that one! I can be pretty certain it's not healthy, but I don't know if it's fatal or anything. As for DoW3, I never played it so can't tender much opinion - the plot was... intriguing, but I'm not qualified to judge.

yeah, one problem Warhammer fans would have with dawn of war serious is how khorne and his demons operate in the game, I doubt khorne likes exterminatus considering how impersonal it is

From what I gather, Ork spores are designed, and I do mean DESIGNED, to infest soil to create a new orks. With this I think its safe to assume that the human immune system will eventually destroy the spores, or the spores will behave with a toxic effect, like black mold. You wont be infested and turned into an ork/human hybrid and an ork will not burst out of your chest. That said, you could definitely end up with anything from a sinus infection, to acute/chronic pneumonia, to poison damage to your sinus' and/or lungs. This is all speculation anyway. Another thing of note, is that the spores are needed to penetrate the soil so as to create the sack that the orks grow in. With that, making the spores present in ork blood so that it is ensured to reach the soil makes the most sense.

Yes; there's a log on Astartes Dreadnoughts and one for those not in the Imperium.
