Blood Knights intro

The Blood Knights, mechanically, are a Space Marine army with allied Grey Knights. They're a force of few models, focusing on more powerful units and using the Space Marine units to fill out functionality and flexibility not available in the Grey Knight list, such as drop pods, less expensive but still powerful infantry, and some uniquely powerful and useful units that complement the grey knights well, such as a master of the forge with conversion beamer on a bike, chaplain, or librarian.

The Grey Knights will be painted like canonical grey knights, and the space marines will be painted similar to them but with more red accents. I'm going to carve up the helmets to more resemble the angled knight mask.

I was looking over the Grey Knights story and it said they have their memories and personalities erased when they join, which is interesting and of course grimdark. They also have their names on their shoulder as well as their personal heraldry, a mix of red white and black colors and symbols representing their deeds or whatever, which is pretty cool.

The problem is who's name is on their shoulder? Their born name? When they have their personalities and memories erased, why does it make sense to keep some name from their old life? I was thinking they might want a new name to forge a new story with, so I thought of this, the first bit of fluff about my subchapter of the Grey Knights, the Blood Knights:

"Grey Knights have their memories and personalities wiped upon acceptance into the secret chapter, to give them a blank slate from which to form their new era of service to the Emperor. 

Knights accepted into the Blood Knights have their name erased as well, and are gifted the name of a fallen brother hero. The name is chosen for them from the sacred list of names of the first Blood Knights. Each name carries its own history, starting with the Brother Knight who carried it into the chapter, and including every Brother since who has carried that name and become joined with its history. Some names on this list have had hundreds of Knight Brothers bear them and add their own deeds to its character. A very few names have had only one owner, such as Grand Master Allimus himself, who has led the Blood Knights since their creation 3000 years ago."

I think it's a neat idea that a name would have its own history and would be chosen for you based on your new personality. Maybe there'd even be a time when you wouldn't have any name, after having your identity wiped but before getting the fancy grey knight power armor and nemesis force weapon of your own, where they would observe your forming personality and match you with a name of fitting character and history when you've earned it.

The space marines have their scouts, neophytes hoping to live long enough to earn sweet power armor. Blood Knights have the Nameless, which is anyone who isn't a Grey Knight but still is a full space marine. Basically anyone on the space marine half of my list is one of the Nameless, even sergeants. The SM commanders and special characters probably have names and would be considered fully part of the grey knights even though they're not Grey Knights in gameplay terms, so Sgt Chronus, Captain, Librarian, Chaplain, Master of the Forge, etc would all have names and heraldry on their shoulder even though they're not tromping around with NFWs and technically they're not grey knights, codexwise.

Of course this means the nameless are still psykers, since all grey knights are, but I'm just adding one more rung to the beginning of the Nemesis Force Weapon upgrade path, where they havn't even earned the right to wield it yet.
