DiY chapter idea
So I want to make a DiY chapter and I was thinking about why they might have been founded. I want to make a chapter that was special ordered by the High Lords to accompany a Rogue Trader's fleet. Like maybe they owed his family a HUGE favor or something. This particular fleet also has large numbers of Mechanicus and Inquisition ships and operatives, as well as Imperial Guard. I was thinking the reason for this could be because they were looking for a STC design for more stable plasma technology, somewhere in the eastern fringe, as well as combating the tyranids. Therefore attracting the attention of the Inquisition, Mechanicus, and the Rogue Trader who is along for the ride either because he heard the rumor, wants the tech for himself, or just wants to explore the fringe, or all of the above. What do you guys think about this idea?
Also, does anyone know the names of any famous and powerful Rogue Trader families?
