I'm looking for a long term roleplay partner who is well versed in 40k lore to fill the role of mostly Rogue Traders while I play the original OC Xenos race I came up with during my free time and try my very best not to get them killed. This RP takes place in the Calyx Expanse a few centuries before the Angevin Crusade shows up so the OC Xenos will probably have to make a run for it in the long run in order to survive.

The original OC race in question are known as the Nephites. Long story short this race was originally enslaved by the Yu'Vath and modified to be both fighters and labourers but the Nephites eventually overthrew their masters and are now independent and largely isolationist. They suffered a number of attacks from other hostile factions over the years and have a powerful grid as a result but aren't particularly interested in expansion. Appearance wise the Nephites look a lot like a bigger and more heavily built version of the Drow from DND. They also have an army of Servitor like robots that look like the Supersoldaten 1960 from Wolfenstein.

Here's a preview of the RP below.

Chapter 1

Calyx Expanse, Tabula Rasa System, Planet Sheol

Year 62 of Millennium 39, Age of Plunder

The lone male Nephite watched from the observation spire, the glowing yellow irises of his eyes, usually alight with the excitement of discovering some fantastical new stellar phenomenon were now hardened stone. The scarlet sun of Sheol painted the horizon in brilliant hues of red and black, a daily spectacle the Nephites usually found comforting.

Today, however, the vibrant display was overshadowed by a more unsettling phenomenon in the star-strewn void above. The anomalous blip on their long-range scanners had initially been dismissed as solar flares or some other astronomical quirk. But the blip had resolved itself into something far more tangible and far more worrying: Three vessels, immense and radiating an energy signature unlike anything the Nephites had ever encountered. The lead vessel, a baroque monstrosity of gothic architecture and brazen display of power, dwarfed its two escorts, frigates that nonetheless bristled with weaponry and an aura of cold merciless brutality.

These ships were not of Nephite design. They were not even of the known factions of the surrounding regions, as catalogued by the Nephites limited star charts, painstakingly compiled over centuries of patient observation. These were… Foreign. Alien in a way that transcended mere biological differences. The Nephites were a species of dark grey skinned humanoids inhabiting heavily fortified obsidian palace cities in the most temperate zones of Sheol. Their physical forms, great in stature, heavily muscled, mildly psychically active and powerful enough that even the frothing green skinned barbarians perpetually infesting Sheol's dark forests could easily be dealt with, assuming they didn't just send in their robotic servants instead. They were a people of inward perfection, of slow, deliberate progress. Conflict with other sentient species was now rare, innovation and curiosity, while present, was tempered by a cautious respect for the unknown. Any new invention underwent an extensive process of testing and refinement before being released into society, both to ensure its safety and prevent unnecessary waste. But now the unknown had arrived on their doorstep, clad in armour plating and powered by massive energies they could scarcely comprehend.

The High Council, a collective of the wisest and most senior Nephites from across Sheol, had convened mere hours after the ships arrival. Debate had raged, echoing through the Council chambers in shouts and declarations. Some argued for immediate retaliation and the activation of the systems strategic defence grid, borderline obsolete relics of a long-forgotten time period. Others advocated for complete isolation, cloaking their cities, silencing their communications and hoping the newcomers would simply pass them by. The Lord High Xenologist, the designated First Contact Specialist, had argued for a different approach: Cautious observation, followed by tentative communication. While the risks were undeniable, the potential rewards – the knowledge, the technology, the perspective of another entirely new civilization – were too significant to ignore. After hours of deliberation, the Council had reluctantly agreed, swayed by the Xenologist's calm rationale, but mostly by the inexplicable backing of the Astral Seers Guild, who up until recently, had simply ignored the various goings on outside of their temple fortress.

The reasoning behind the Astral Seers sudden interest in politics after centuries of self imposed isolation was made known when they announced that this current era of stability and peace was coming to an end and the mysterious newcomers were simply heralds of things to come. They also cautioned that while these current visitors could be reasoned and negotiated with, most of their kind will not be so rational and do everything in their power to destroy the Nephites simply because they existed. The Astral Seers then finished with an even more ominous warning that they were going to have to tread very carefully when dealing with these beings in the centuries to come or risk the very real possibility of being annihilated.

After the Astral Seers announcement, the High Council got to work and that was that. There was no arguing against or even questioning of a seer guild who's predictions had a 100% success rate. If they said something was going to happen, it always happened and anyone who ignored their warnings usually wound up dead.

If they were lucky.

Now, as the lead vessel began to decelerate, entering into a stable orbit around Sheol, the Xenologist activated the planetary comm-array and transmitted the carefully compiled first contact package. Most of the information sent was what the Lord High Xenologist deemed safe for this type of situation such a hopefully translatable version of their language, basic cultural information, an abridged version of their history and while information was given on their military capabilities, most of it was massively downplayed as a precaution. Anything permitting to their former Yu'Vath overlords, the Chaos insurrections or the Nephites psychic abilities was omitted completely. There was no telling how the visitors would react to that so they played it safe for now.

After sending the transmission followed by several hours of nerve wracking silence the Nephites finally received a response “Greetings, inhabitants of this system. We are the Indomitable Spirit, a vessel of the Rogue Trader Lucian Atreus Marius, under the authority of the Imperium of Man. We come in peace, seeking trade and… Enlightenment.”
