You are free to pick up where you left off, I don't have time to make a full post right now but you left off by opening a bottle of Amasec after learning of the world the old Rogue Trader had left behind, along with deleting the AI that was left to keep the place while the heir arrived.
As the day turns to dusk, each of you begin to explore the manor. While almost all imperium homes tend to be adorned with aquila, skills and other symbols of the holy imperium, this home is severely lacking such adornments.
"My dear grandson,
By now I am sure you have deleted the piece of me I left behind, I Have one more thing to give to you, our history. Before the Emporer, before the dark age of technology, before we were truly space fairing.
Among my books, you will find text that goes back to 1538. We have always been nobles of Terra. Our family stood next to the leaders in secret acting outside of the public eye and its laws for the betterment of all life. Trading with those deemed unclean and unfit by the masses. Our family traded with sworn enemies during Terra's greatest conflicts. However as the years went on, they no longer seemed like enemies. They just seemed like people caught up in something so much bigger than any of us could truly understand. Eventually, we pseudo-separated ourselves from the royals and nobles and slipped into secret alliances with those we called enemies becoming a neutral party, and solid ground for those who no longer wished to participate in the eternal conflicts.
This place is our leagacy, one your father was too indoctrinated to see...the I used to be unable to see. The Emporer knew us, who we were. My great grandfather told me of such things but I never wanted to believe. Until my first trip to Holy Terra. I was delivering a man to the High Inquisitor who had run far out of Imperium space. As I walked the streets, I saw the fear washed onto every man, woman, and child's ashen face. I saw the truth of this 'great' Imperium and sought better. When I found this planet I remembered the tales from the books my great-grandfather had kept from long long ago. Its description of sandy beaches and lush fields of green. The fresh air and warm sun. I remembered how none of them were present on Terra, nor most Imperium planets anymore. Over time I was put into dire situations where the aid of a xeno was required. The man I have asked to run this settlement in my stead, Ukos Kais, I was stuck in a cave with him for a week whilst hiding from a tyranid attack. Originally we were there to take an experimental weapon that was to be examined by the Mechanicus on Mars. However, the Inquisitor had failed to mention that the Tyranid were our distraction for getting into the base. During this time I got to know the man, as he was the central intelligence for this weapon and we needed him. We started by butting heads and arguing over everything, once the hunger set in, we stopped bickering realizing that this wasn't the time. Silence got the better of us so we talked. It was then I understood, he was no different from any of us. He doubted the "greater good." and the Etherials, but still saw us as the greater evil overall. I shared with him my doubts about the Imperium.
I hope in time you will see things the way our fathers say the world. How the Emporer saw us.
I trust your decision,
Gaios Du Leonis"
Looking up from the letter, you take a closer look at the shelf, stretching from one end of the wall to the other. On it sits several books on display, the oldest of these is dated for "1538" the text is almost impossible to comprehend, but it is clear that its a journal from someone in the du Leonis line"
Matthias leans back in a plush chair when he finishes reading the note and pours out another glass of amasec.
"To you, Grand Dad." He says to the empty room before knocking the glass back. For a moment, the Rogue Trader allows the enormity of everything; his inheritance, the 'heretical' nature of the magnum opus of his family line's work, and a planet full of xenos.
Matthias lets out a deep breath before getting back up and reading some of what journels have survived the ravages of time until sleep takes him.
Balthisar is displeased as he walks the halls of the Rogue Trader's new home.
"Your grandfather's taste in decor is bland and unfitting of his station. You should consider redecorating before the populace gets the wrong idea about how they should interact with you." he mentions as he stalks off to see if he can find anything more interesting.
The STC room would be eyeroll inducing, if Balthisar had any to actually roll.
"No respect, no understanding. Simply written out for the laymen to believe they can interpret, and not even a lock on the door to save them from themselves."
He is not so zealous that he can't appreciate the wealth of technical knowledge contained within these STCs, but one look at the room is enough to firm his resolve that the high priest of this world is irresponsible, and reaches beyond his grasp.
He shudders at the idea of some random citizen or guardsman, jumped up on these ideas, taking it upon themselves to replicate one of the weapons found within this room. Their failure might be even more terrifying than their success given some of the components at play.
Kromp aimlessly wanders the halls of the manor, exploring the rooms that are large enough to hold him comfortably, while checking for potential threats. That's one of the things you're supposed to do as a bodyguard, but he isn't quite sure what a 'potential threat' would look like on this planet. He eventually concludes that, if he doesn't find anything in here that's weirder than what he's seen outside, it should probably be fine.
Kromp had never seen so many xenos in one place...at least, not so many different kinds. He had always been taught that the Emperor hates xenos, so he should hate them too. But it's easy to hate a xeno that's trying to kill you while calling you a "mon-keigh" or screaming "WAAAGH". These ones seem...different. Do they really deserve to be wiped out?
Eventually he comes across the master bedroom, where he finds Matthias fast asleep in a soft-looking chair, with an open book in his lap. Kromp had never understood how reading worked. He learned how to sound out the letters on a page, but apparently you're supposed do it in your head somehow. Then the letters are supposed to tell you stuff that you didn't already know, but he'd never figured out how to make that happen. He'd long accepted that it was just one of those things other people could do that he couldn't. But whatever Matthias had been reading seemed to have tired him out as much as any reading tired Kromp out. What kind of book could be too much for the brilliant Rogue Trader to handle?!
Then Kromp remembers the look on Matthias's face just after they came into the manor. He still had his usual smile, only it had started...sagging. Like holding it up was taking a lot of effort. Matthias had once told him about the concept of pretending to have feelings that you weren't actually feeling - another one of those things Kromp had never figured out how to do. Still, no wonder Matthias had fallen asleep, with combined the effort of using that pretend smile and reading that tricky book!
Making sure not to wake his master, he grabs a sheet from the nearby bed, drapes it over Matthias as gently as he can, helps himself to a quick swig of amasec, and leaves the room with all the stealth he can muster.
