Deep in the heart of a wrecked warmachine on the ruined planet Zayth, Jak Frost is questioning the last priestess of Mykybe, Zaythi Goddess of Love & Good Fortune, about the mysterious Veil, source of the X-1 archeotech that has since vanished from under the nose of Acting-Captain Marzu. The priestess's mutant offspring move to assist her prognostications, unbolting a pneumatic tube from the wall, draping it around her python-like, and letting her breath deeply of the fumes that have accumulated over the centuries. Her vision is suitably oracular and ambiguous.
Priestess : You have seen the veil, held before the Goddess that she not drive Man mad with her beauty... I see you tread the path of the thief and the avatar, see you follow in their footsteps to the place of light... but I see only darkness! There is a place, like this, writ large, where they lay offerings before the God of Flesh, and pray for the return of the Gods of Iron, and they know nothing of the world beyond! *long string of babbled Navigator's Cant* I see you seeking a pearl of great price, but you are not the only ones who seek it... seven after seven after seven... you will be damned by your greed... I see war in your future... Damaris! Oceans of blood! Beware the beastman! Beware the creatures beyond the Veil! ..... Make haste! The demons are coming!
All annoyingly vague, and worrisome, and generic. Are these Gods of Iron heretical robots? Khornate Chaos Marines? And Seven is the number of the Ruinous Power Nurgle... Although those co-ordinates may actually mean something concrete, and are relayed to Benetek.
Jak Frost : Well, that was all very obvious. Beware the mutants! Beware the Orks! Beware the Tyranids, they're quite nasty... Beware the Stinky Cheese! I wonder who that refers to?
Acting-Captain Casu Marzu : I can't imagine.
Jak now has to decide what to do next - the Priestess begged him to show kindness to her people, but they ARE all mutants and witches, so he would be entirely within his rights to hose them all down with gunfire and have the site nuked from orbit. Instead, he decides to make it Somebody Else's Problem, and persuades the landship Ironclad that detouring to ransack the war machine for salvage is worth it, especially if they get a priestess and oracle as well. The Rose Tattoo's Tech-Priests want to spend the weeks until the Ironclad can crawl there studying the machine in depth, of course, learning everything they can of its technological arcana. This Jak hesitantly approves, on the condition they don't punch holes in the still intact sections, and take precautions against being blown away by the next superstorm.
Up on the Rose Tattoo, we learn more of what has been keeping Marzu too busy to meet with the Zaythi. He's ordered a complete breakdown on all data-security logs and power usage for the ship, searching for any evidence that the X-1 is still on board and trying to infiltrate the data-vaults. It doesn't appear the Inquisitor and his retinue had it in their possession, despite his scans of their quarters.
GM : You really want to scan the rooms? It's generally a very bad idea to take an interest in the activities of the Inquisition, lest they reciprocate.
And Inquisitor Lammergeier's interest in Lord-Captain's van Baroque's illness has him worried as well. Leaving the Lord-Captain in suspended animation, citing the risks of trying to repair his brain without the very best chirugeons to hand, has been convenient for Marzu's megalomania, but if the Inquisition are so intrigued by the case, than perhaps he should try and repair the damage himself, even if organic brain tissue is such a poor substitute for the purity of silicon.
GM : So Marzu spends a few days bent over a microscope, operating on the Lord-Captain's brain. *looks innocent*
GM : Anything you want to inscribe on the Lord-Captain's new steel plate, before you sew him up?
Jak Frost : A *****.
Acting-Captain Casu Marzu : Hey, that's not fair. I wouldn't do anything like that.
GM : No. You'd nano-etch it in figures a few molecules high.
Acting-Captain Casu Marzu : Not true. I like the Lord-Captain. If it wasn't for him I wouldn't be out here giving orders and doing whatever the hell I like. BWAHAHAHA.
Tech-Priest Casu Marzu : Good news, crew! The operation was a success! Our valiant Lord-Captain will soon be fit to resume his command!
GM : 'Just ignore this remote control I'm holding.'
The Lord-Captain is cautiously pleased to see that his ship is still intact and most of the crew still alive, despite Marzu being in command. However, the confession that the X-1 Unit is missing nearly puts him back into a coma.
Jak Frost : How could you loose a box???
Tech-Priest Casu Marzu : It..... good question!
Jak Frost : Were any the Inquisitor's acolytes carrying a box big enough to hold it?
Tech-Priest Casu Marzu : Cylinder. Round ends. It was an X-box 360 
Lord-Captain van Baroque decides to punish Marzu and Frost - by promoting them both. Jak will now be responsible for the ship's financial endeavours, and Marzu will handle the details. ALL the details.
GM : Clever. You can sit back and relax, while Jak strangles under the responsibility, and Marzu drowns in the paperwork.
But first, the results of Marzu's electronic security checks are coming in. There's no evidence of the X-1 being active in the last few weeks, but there are some peculiar oddities over the last few months. Tech-Priest and Lay-Technician cognomens being used to log into the ship's systems at points far removed from where those crew members should be. Cross-referencing them to the Rose Tattoo's camera records, patchy as they are, reveals something alarming - they have a Tech-Priest aboard that Marzu doesn't recognise, and this individual has being going from section to section of the ship, avoiding the Enginarium and Command Spire, familiarising himself with the layout and systems, unchallenged by the crew. A Tech-Priest IS a good disguise - the robes conceal much, and mere crew dare not question what he is doing lest it intrude upon the sacred mysteries of technology. Jak immediately passes on a description to the various joy-girls and scum he found places for on the ship. Van Baroque does the same with his own spy network among the crew. Marzu determines that the intruder has an unhealthy interest in the Rose Tattoo's Munitorium, and its life support systems, and Malakai determines that the now unused Alienage, cleared as it is of missionaries, and powered down to divert extra power to the ship's sensor arrays, would be a good place for a spy to hide. He leads a thorough search, and indeed they find something interesting - one of the Alienage's comm-lines has been hacked, with a socket for a burst receiver/transmitter. Jak rigs a concealed camera to watch the area, in case the spy comes back.
Jak learns that the fake Tech-Priest has been seen in the ship's sewerage works, where, for reasons of Tradition, rickety walkways hang over the bubbling vats, and talks to the sergeant at arms responsible for that section.
GM : It's not one of the most prestigious postings on the ship.
Jak : That's an understatement. Have you seen this Tech-Priest doing anything unusual down here?
Sergeant-at-Arms : Well, sir, no. He said it was a surprise inspection.
Jak OOC : Clearly we need to consult the Evil Overlord list. There are no such things as surprise inspections. Anything else?
Sergeant-at-Arms : Well, we had that outbreak of ****-flies last month, but we got it under control.
Jak : Oh? Did you use flamers?
Sergeant-at-Arms : Oh, NO, sir! No naked flames down here!
Marzu, Jak and the rest inspect the Munitorium, directly over the sewerage works.
Tech-Priest Casu Marzu : Have any of you seen any Tech-Priests in here? Raise your hands.
Munitorium Servitors : .....* all raise hands, power-lifters, etc.*
Jak : Tech-Priests other than Marzu.
Munitorium Servitors : *all lower hands*
They place extra guards on the Munitorium, pending the capture of the spy. They don't want him dead just yet, in case he's an Inquisitorial agent. A suspicious hotspot on one of the Munitorium walls turns out to be an illicit still in one of the gun-decks. The gun crew clan in question is relieved that Marzu isn't angry about this - he's understanding about their needs ( providing the design is one of the approved Illicit Still Configurations )
GM : After all, it saves on industrial solvent too.
Unfortunately all this running around searching for the spy has left the rest of the ship in the hands of the ordinary crew. And even with the extra sensor arrays online, they completely fail to notice the four Ork raiders coming in to attack, until it's too late.
GM : The Oracle told you that the demons were coming...
Jak : That could have meant anything!
Lord-Captain van Baroque : Orks? Excellent!
GM : Yes, more heads for your trophy room.
Happily, the Orks prove spectacularly incompetent at everything, from shooting to boarding to even maintaining morale. After the lead vessel Big Loota gets blasted out of the sky, Marzu even manages to intimidate the second into leaving to find an easier target elsewhere.
GM : Possibly your threat was a bit wordy for Orks.
Lord-Captain : 'You grotz ain't fit to sniff da dags of Ghazgull Thraka!'
GM : Better. 'You like all dat dakka? Well dere's plenny more where dat came from!'
GM : I can only assume that first wave of Ork boarders attempted to board via the Rose Tattoo's engines. While they were running.
Eventually, the Rose Tattoo having run rings around the other four ships, noses up behind the last, which is so damaged it can only go in straight lines, and has no rear-facing weapons.
Tech-Priest Casu Marzu : See that Ork on the stern? Waving the white flag? Target the main guns on him first.
Jak Frost : I can imagine the conditions on their ship. 'Hey, Boss, is dat dere air dukt supposed ta be spitting fire like dat?'
But Malakai realised something in the middle of battle - even with the firefight raging, he really should have kept the Munitorium locked. Because within minutes of the Orks defeat, and the crew drooling over the thought of the loot they can capture from the hulks, a massive explosion rips through the armoury and the adjacent laser batteries. In retrospect, the middle of the battle was the best time for the spy to make his move.
Malakai : All he needed to do was be on one the gun decks, 'blessing' each shell, and have one sent back to the Munitorium as defective.
GM : *nods* Just as well you dealt with the Orks so quickly - imagine how bad it would have been if the Munitorium and Sunsear batteries had gone up during the battle? Could have been worse - the explosion could have blown out through the crew barracks, or down through the sewerage works. That would have been a short sharp shower for the planet below. Of course, given the conditions on Zayth, they probably wouldn't have noticed.
The explorers order a total lockdown of the ship - they're going to find this agent if it's the last thing they do....and it very well might be.
A few quotes, whose context I have forgotten
Jak Frost : Pardon me, my pants are shaking
Lord-Captain van Baroque : Necrons dancing the Robot.
Jak Frost : Tech-Priest/Necron Dance-off!
