So a while back my players made the 'bold' decision to go wandering through some space hulks they came across looking for shiny things. They were on their merry looting way when they discovered what made that decision so bold, and the seneschal and arch-militant were promptly devoured by genestealers.
I've since then made them aware that they didn't quite leave every monster on the dead ship, and that people have been disappearing from the lower decks. So far, they've been content to let them munch on the crew as they please, and have done nothing about the problem. A foolish choice to say the least, and one they'll come to regret.
One of these days, the cult is gonna have to make an appearance (assuming the Inquisition, the Eldar, and the navigator's lousy rolls don't get them first), but I'm a little stuck on how to make it play out. I've been thinking of having them show up in the Processional of the Damned (we're running Lure of the Expanse right now), wherein they find the remains of their own ship overrun by the cult. The books have some good profiles for genestealers, but no real info on hybrids. I'm wondering how strong these should be. Does making a hybrid make them stronger, or would that just dilute their already incredible strength? Would they be more cunning? Agile? Intelligent?
Let me know what you guys think! However I play it out, it needs to be the single most horrifying experience of their lives.
