hey @Ronanbelleza123 I have a Warhammer 40k story idea basically a Rogue Trader OC x Warhammer 40k where your OC Ronan is part of the Rogue Trader Belleza Dynasty the largest and most influential and wealthiest Rogue Traders of the Imperium they are one of the many first rogue traders whose warrant of Trade was signed none other than the Emperor himself before the start of the Great Crusade which gives you authority next to the Order of the Emperor Holy Inquisition (which was founded by Malcador the Sigilite during the Horus Heresy) your dynasty of a 100 worlds or more (if you wanted to add more) is bordered between Segmentum Pacificus and Ultima Segmentum, your Family is the First to own a Apocalypse-Class Battleship (most rogue traders use Frigates, Cruisers and Grand-cruisers as their Flagship and example is from the RPG game Rogue Trader the MC ship is a Firestorm Frigate), your dynasty has commandeer a huge Battlefleet of Ships that protects your Rogue Trader Empire (typically a Battlefleet is somewhere between 50 to 75 depending on how important is the sector yours is somewhere bigger like a near crusade level fleet), your Dynasty has huge connections with Adeptus Mechanicus and Militarum and also several Chapters of Astartes (back during the great crusade your ancestors has gained some favors with some of the Primarchs and Legions) one of them is the Ultramarine Chapters. Back before the Great crusade your ancestors during their explorations and scouting new worlds for the Imperium they have found not 1 not 2 but 6 fully intact, not corrupted STC like really Intact STC in a span of 200 years now being a Rogue Trader means that you can give this STC to the Mechanicus and your family would be more influential and giving more power and influence and worlds and fleet and advance technology but your ancestors are not like any Rogue Traders instead of giving the fully intact STC for the great of the Imperium and Humanity they instead keep the STC for themselves
