The way your request was written made my day. So, there you go:
The thing is set on a Hive World of Malfi. As seen in Core Rulebook, Malfian Nobility is a bunch of self-absorbed pricks, endlessly plotting against each other. Somehow, Lord Governor of the Calixis Sector manages to look in another direction if something brutal occurs, but this time one of the Noblemen gets accused of financially supporting the local rebellion. The consequences are grim - The Inquisition kicks in and starts the investigation. The air suddenly smells with fire, steel and rotten guts.
How do you delve into such individual's deepest secrets without alarming his peers that they should expect Imperial Inquisition?
The Inquisitor hires a bunch of worst bastards he could find to get into, blend with and gain support of one of the most numerous criminal organizations of the Underhive, because rumor has it that the leader of the pack is - completely coincidentally, of course - planning on a heist, right in the hypothetical rebel's mansion.
Of course, they are most probably going to die trying, for the Underhive is a really bad place to live in...
There will be some intrigue, some more violent shootouts, and - most of all - some moral dilemmas for those who just buy this kind of stuff. What's the difference between the Crime Lord's attack dog and the Inquisition's attack dog, anyway?
Dramatis Personae:(in order of, well, remembrance?)
Klear as Lijah MkLear - quick-talking dashing rogue from the world of Tanith. Hides some dark secrets to be revealed later.
LuckyDee as Lazerus - gun-totting bandit of lizard-like appearance. His most notable skill is staring blankly for undefined amount of time.
HexaDoken as himself - unemotional, laid-back gun for hire. His back looks like a swiss cheese, a dozen holes punched with gunfire. These are of sentimental value, since the mercenary refuses to be patched up.
Esther as Xilla - sneaky assassin from the Moritat Death Cult, sent by the Inquisitor to "keep an eye for these dirtbags in case they'd done something stupid".
Sylith as The Seer - walking enigma. It's hard to decide if she's just an exotic, sophisticated fortune teller, or an inquisitorial agent in disguise. Or both.
Silharr as The Game "Master" -
"Absolutely! I'm da boss!" - He claims that reading makes it harder to host the game, so he doesn't, just throwing in random people and events.
So far, we managed to:
- Irk the Inquisitor. Do bear in mind, he's half-machine and generally not prone to being irked.
- Enter Hive Malfi's sewers;
- Avoid getting eaten by a monstrous spider, by means of shooting his ass off;
- Get radiation sickness;
- Avoid drowning in a hangar full of leaky pipes;
- Get to the outlaw village down below the Malfi city;
- Meet the Seer and inquiry her for a long, long time. Also, eat a fish.
And all that only after 22 pages of rough role-playing!
Now, the group is heading towards the village saloon. I feel for them. I wouldn't play it sober, too.
