I know my players will eat it up. We ran Broken Chains ... and one of those pregens went on paper when the Core book dropped at Gen Con. This provides continuity of a sort. I'm setting up Hand of Corruption by subtly editing the other adventures. We are in Rivals for Glory . One of the star maps the Liege had (they bargained for them by doing favors for Vycraft) will show where Saint Annard's Pennance once was. Essentially, there will be a planet-sized "Warp Shadow" with no world in evidence. A little digging will reveal the planet was there...now gone.
I have one player who will literally burst into flame when this fact is uncovered. False Prophets will promise more info, and finally they'll be off to find De Orbis Mysteriis . They might win the book in a card game, but they'll be lead to him (forget his name suddenly) by either Palmere Grath or someone in False Prophets . By the time we get to actually playing out of Hand of Corruption itself, they'll be out of their minds with joy over the idea of owning a whole planet.
Vycraft...I'm using him as a template for what my wife's character (an Apostate) will eventually be. The Shadow Leige controls a small patch of rainy little Sacgrave. She's already said he sets his sights too low. For all his weird power (I had him refer to things players had only told me..or referred to the heretek as "throwing off the Chains of Judgement" so that he appeared all-knowing) he's a Big Fish in a Very Little Pond. Next episode, the Psyker gets to see his future self.. then we start screwing with our group's Night Lord CSM. I've got other examples of where the PCs are heading, like the scene where Frodo looks at Gollum and realizes Gollum is a mirror... that's what I want.
The Heretek, Hephaestus Bore from Broken Chains , will see himself in Tech Priest Rebis... and try to avoid her fate. I've been using the word d oom a lot. Mostly as a sound effect. Even had a litte auspex that pinged a tinny-high-pitched "doom....doom...doom" when approaching the Deluge in Rivals . They know the worst is coming. They just don't know what it is.
When the Necrons do appear, the players won't be fighting for their treasure or mere Infamy. They'll be fighting for a world they've spent months working toward, dying for... they'll be fighting for their home. (or the closest thing this band of deviants can ever call home).
Frankly, I pity the Necrons.
