I hope this isn't too out of left field, but I was inspired by the VtM crossover prompt in the apocrypha. Please keep in mind that this and Reluctant Sith Lord Darth Cain are my introduction to 40k and I haven't gotten to the books. I don't actually have a plan here, anyone is free to pick it up.

Baron of Perlia
…

It is the dawn of a new century and for all that has changed since the Emperor's foolish invasion of the Russian empire, Cain remains trapped by an absurd reputation. Cain could count on one hand the number of people who were aware of his true nature.

One such person was an Anarch by the name of Smiling Jack who delighted in the discordance between Ciaphas Cain's reputation and his feelings about said reputation.

Starting as a pirate in the 1600's, Smiling Jack is infamous for the chaos that tends to follow in his wake, as if attached to the heels of his shoes. Rumors tell of the disasters that seem to befall Princes and other high ranking kindred who the man takes a dislike to. For that reason Ciaphas tries to avoid the brujah when he visits Perlia, going so far as to be on the opposite side of the city from wherever Jack is sighted. The key word here is 'tries', as the Anarch enjoys digging into whatever issues Perlia is currently dealing with, and circumstances always seem to set Cain right into the fray.

Case in point, right now in a small warehouse on the outskirts of Perlia.

BOOM

Jack's bomb, which he did not know about, took out the entire building, along with the Sabbat's horde of szlachta that had chased them from the other side of the city.

If there were others around, Cain might have to put on a brave front as everyone starts praising him for bravely luring away the mutants into Jack's trap that obviously Cain knew about beforehand.

Fortunately they have a while before everyone catches up, so there's a brief window to break down before getting back to the baron act.

"What the fuck!"
Both hands are gripping my hair while I cry out and start pacing. If vampires could sweat I'd be dripping buckets.
"When did the sabbat make so many szlachta? Why did the sabbat make so many szlachta? Perlia doesn't need this. I don't need this!"
"And you!"
I whirl around to point a finger at the brujah.
Jack is laughing. They barely escaped being torn apart before burning up in his explosion, and Jack is laughing.

"Fuck you! Why do you keep bringing explosives into my city? Knock it off!"

"Ha! Need something for the monsters you attract!" And the usual firepower doesn't cut it, gotta have something with a little more 'oomph'."

"Your 'oomph' is giving me flash burns. Every time we meet I get new scars!"

The sirens are much closer now and I begin compartmentalizing in preparation of the upcoming performance. Kasteen can be counted on to bring order to the areas that had been ravaged by the gargoyles. The mortals will need an explanation, but by now Perlia's media network was well versed in explaining away kindred activities.

The biggest concern was how the sabbat had managed to set up in the city without any warning. The idea that our security teams might have been slacking is ludicrous, usually I have to step in and make them take their time off (overworking employees will lead to resentment which leads to bloody revolution!).

Which meant the Sabbat either found or made a new way into the city. Daminit all!

The only one in the Sabbat who would be dedicated enough to do all this is that maniac Vara. The Tzimisce refused to let go of his (frankly self-inflicted) humiliation from consistently failing to take down Cain. The only good thing to come from that man was that the rest of the Sabbat had seen his many failures and took it to mean Perlia should be avoided at all costs.

While the emergency responders get to work Kasteen walks up to me. No doubt to make an absurd comment about my ability to take on a horde of Tzimisce crafted supersoldiers.

"Hell of a way to end a hell of a chase, but maybe give us a heads up about the fireworks next time. "

See? They're already assuming I planned this from the beginning. And what do you mean next time? I wish there hadn't been fireworks this time!

Jack chuckles at the byplay and gives me a soft (by kindred standards) slap on the shoulder.
"Hey, when you're done with the clean up crew let's go somewhere a bit less exciting. There's a guy I wanna introduce to you."

What a terrifying prospect. But it's not like I can shout "Hell no!" while running away, not with so many witnesses. No doubt Jack had waited for the others to arrive specifically for this purpose. Instead I give a confident nod and set out to help the responders. Of course, had I known just who I would be meeting I would have done exactly that, regardless of the witnesses.
