, if I'm not mistaken.
That would surprise me, because I have Rogue Trader and have never seen that before. Certainly it's not in either the marine or the eldar sections.
There were a couple of compendia and sourcebooks which came out shortly after. Maybe one of those?
And the reason they did this was because despite being purer than the Emperor himself - the Emperor at least being known to have fathered children - they feared falling to corruption, while the Sororitas they slaughtered and used as warpaint were pure enough to withstand the corrupting influences of a bloodthirster relic.
The thing that bugs me the most is I can see (just about) how a heavily re-written version could work*, but the worst thing about his writing is that he creates non-sensical situations and then doesn't provide enough background to explain how it could make sense, he just leaves it as is (with you alternating between confusion and rage). Or he pushes it too far. I could, for example, see the Blood Angels and Necrons fighting alongside one another against the Tyranids (note 'alongside one another', not 'in alliance'), but not 'parting afterwards without immediately going back to war once the bugs were dead'.
One of the things I like the most about Daemon Hunter is it is, amongst other things, a decent writer doing a quick once-over the description of the organisation and wargear referred to in the codex. Smooshing Interceptors and Strike Squads into one thing, for example, and pushing them far more to the 'power-armoured nightcrawler', whilst making the purifiers much more the scholar-warriors (i.e. a librarian not in terms of psychic power - because they're ALL psykers - but in a sense of "the scholar who spends time in a library).
The black library authors don't seem to like him much more. Aaron Dembski-Bowden is most fascinating to listen to, because you need to bear in mind he was half-way through writing The Emperor's Gift when the new codex draft landed on his desk. I get the impression that a few bad words ensued.
* Not as described, I hasten to add. They don't need spiritual protection.
But grey knights are big on sacrifice to sanctify armour; if said big daemon was powerful enough to rip through even the physical protection of Aegis armour, an additional layer of protection in the form of wards drawn in blood might let them live a few seconds longer - maybe just long enough to banish it. Provided the blood was from someone pure (i.e. sororitas or other grey knights). Where the story falls apart is that this isn't the sort of protection implied, and that that sort of thing has to be willing**.
I could see the sororitas in the extreme voluntarily sacrificing themselves somehow to aid the knights against heresy incarnate, but ward's writing gives the impression the Knights didn't bother to ask, went "oh, sod it", teleported into the convent and just started hacking them up with nemesis weapons and as a result they weren't inconvenienced at all by the daemon. Which is...well....there's a reason it gets held up as the worst example in a gallery of fail.
** See the closest equivalent I can think of; the Justicar Alaric short story Sacrifice. Which, by comparison, is awesome and a piece of fiction which feels totally right for the Grey Knights, despite covering virtually the same topic.
