I'm starting up a game with a few people soon, and I was thinking I'd do an overarching plot with some rogue tech-priests being pursued by the party, since my players have indicated that at least one of them wants to play a tech-priest and I thought it'd be an interesting idea.
Now, I'm thinking the first attention will be the team being sent to investigate a case of some people going missing in a hive. While this isn't unusual in hives, there has now been several arbitrators gone missing, along with a fairly-high-up Administratum official, and the Inquisition has taken an interest.
Since, despite an Inquisitor taking interest, this case is... minor, a very expendable and new team has been sent. This is basically my starting point, and I'm thinking they'll eventually find traces of an abandoned lab used for some kind of heretical research on archeotech, and this'll be the plot hook for launching a pursuit of whoever did it.
Now, I need some ideas for what to do afterwards, and what to use to make the first mission a bit more fleshed out. Any ideas?
