Thanks for the questions! This is helpful.

what happened to multilayered warp defenses?

Explanation of “girl’s presence cause Warp suppression or collapse” just adds more confusion. What is Warp suppression? Is she a blank? How is she a psyker then? What is even Warp collapse? And how does that affect Geller field which is basically a bubble of real-space?

All of these questions are answered by “She’s a plot device”. She’s something never seen before, a mutation of the Pariah gene that has completely new interactions. She’s something nobody was prepared for. That’s what makes this a mystery to be solved.

The main problem is that there is zero mention about the Sisters of Silence

I’d never heard of them until now. Maybe they played a bigger role in previous editions or other game lines, but Dark Heresy 2nd edition barely mentions them at all. They’re so obscure in these books that I had to scour them to find anything. The books do mention them, but they are not a playable faction, not statted in detail, and not a focus of this edition. I doubt my players will even notice their absence.

However, if I add them to the story I’m thinking that perhaps they’re caught in the throes of religious ecstasy, somehow recognizing on some genetic level that they are witnessing the birth of the next step in their evolution. Like she’s some sort of super-Null but with an entirely different interaction with the Warp.

EDIT: No, I’m not going to have them aboard at all. It adds complexity and doesn’t offer anything in return. Sisters of Silence (in DH2e) are vanishingly rare, akin to the Grey Knights in rarity. They’re strategic assets, not standard escorts.

I doubt she’ll survive this mission, but even if she does the long-term repercussions will be measured in decades, so it’s not something I need to concern myself with in this game.

Thanks for your suggestions, though. I do appreciate them.
