Apologies for the late reply - I've been away for a while.
As for the chapter, I've sort of being toying with writing the fluff for a chapter of my own meager design chops. Kind of settled on the name of "The Iron Talismans" and the thought that I had going through my mind was that they were reduced to a shadow of their former selves after a derelict chaos cruiser was sent on a collision course with their homeworld whilst the majority of the fleet was engaged elsewhere. Not exactly original, I know, but one does what one can

They conduct their quest for vengeance out of the sole remaining fortress monastery that has a handful of strike cruisers, attendant escorts and Fleet masters' battlebarge. That kind of explains why the fleet cannot expand further, which works in nicely with Games Workshop no longer supplying us with kit...
Colour scheme: Dark blueish grey with deep red trim - see my Ramillies for reference.
