This is very good fanfiction but after this chapter...WTF! WHY DID YOU GIVE A SPACE MARINE AURA ARE YOU FUCKING SERIOUS! DO YOU REALLY THINK THAT A SPACE MARINE WITHOUT AURA WILL BE NO MATCH FOR PUSSY HUNTSMANS BICHTES WTFFFFFFFF! IT'S BETTER SEEING HAVE ONE SPACE MARINE WITHOUT AURA KICKING ASS OF 1000 GRIMM OR 20 HUNTSMAN BUT NOOO BECAUSE THE PEOPLE OF RENMANT THINK WITHOUT AURA YOU ARE USELESS AND CAN DO NOTHING AGAINST THE GRIMM. WE COULD HAVE PROVED THEM WRONG BUT NO WE MUST FOLLOW THE RULES FUCKING RWBY AND GIVE THEM STUPID AURA! GIVING AURA TO SPACE MARINE IS THE HIGHEST OF HERESIES I HAVE EVER HAD SEE MERCY! PLEASE CHANGE THAT OR EXPLAIN ME WHY DID YOU DO IT AND DON'T TELL ME YOU DID THIS FOR THE PLOT

No cap I don’t fw the space marines

My sympathies always go out for the Lamenters. If only luck would have that they were easier to paint.

With this whole band of Astartes, we have a whole jolly adventure group up to no good. My favorite is still Dearg so far though. I find his sudden outbursts and mannerisms to be very entertaining. Very flavorful characters.

These prologues are usually a slog just to get through to the "good stuff", but this was gripping. I am in awe. I especially love the way you transitioned between our soon-to-be lost lot.

Lux, Catelin, Delphine, Nell and Vivian Stahl. I am most invested in their further adventures.

Jaune, you're about to experience the best or worst moments of your entire life. Brace yourselves...and your hip bones if needed.

Good chapter. Can't wait to find out what's going on in Menagerie with the whole chaos taking route thing and whether or not Sierra Khan will die in this case. Guess it won't just be the SM's that'll be causing Menagerie's population to plummet.

I will now proceed to ship the scout with Vernal. Also, was expecting the Lamenters. Saw another fic that did the same thing. What I really didn't expect though was them meeting the Space Sharks.

ok this is getting ridiculous you have so many freaking characters that it slowed the story to a crawl...

so much so that you had to use time skips repeatedly to get anywhere like how you skipped a week after the Imperials met the denizens of Remnant... arguably when some of the most interesting interactions and reactions would have taken place...

and while well written grammar wise there is not enough dialogue and its really wordy...
honestly reading this has become a slog...

Jesus Christ this is becoming drawn out... its supposed to be a crossover but so far it might as well be a regular 40k fic...

Jauney-boy's the center of a lewd warrior sandwhich and I love it.

That part between those had me smile like an idiot XD. Great job!(also i ship them now, all three of them ;-))

so sister Delphine is unsure of herself, Blake is possibly on the verge of conversion to the imperial cult ruby is about to suffer a metaphorical heart attack when she sees the super heavy, Yang's about to cause a "Identity crisis for Lux (that's probably not gonna be pretty:(, maybe Nel will be able to help ) and Jaune just accepted/proposed a threesome... I missed this story, cant wait for the Astartes to start trickling in and raising all sorts of questions and I wonder what praf is doing now that he has had a few days? what has olive been doing ? and most importantly what is our "rembrancer" doing right now? also on a side note is kobi the only abhuman among the guard?

Ok, I don’t know if this has been mentioned by anyone yet, but your punctuation spacing need a bit of work, for example:
“Jaune staring quite openly at a rack propped up next to the bed, laden with a the thick verdant green plate and tanned fabric of an armoured body glove, an emblem comprised of a six-limbed reptilian creature coiled beneath a swooping eagle proudly displayed in gold leaf across the chest along with a few other subtle marks she mean some sort of heraldry.”
My Word says its 63 words long, that’s too long for one sentence. You should try to cut it down to smaller, easier to digest chunks. I know you has made attempts, like this:
“Something humorous to break the cultural wall, the sound exiting her throat as a hollow wheeze smothered by misunderstanding however when she noticed the other woman's stupefaction.”
Except it doesn’t works that well, the sentences comes off as disjointed and hard to follow, although that’s might just be you forgot a comma or something.
The story itself is fine, and it is expanding better than most crossover managed to do (the text amount helped). Hope you will get better in future.

Looks like Blake is starting to get interested in the Imperial Creed, well, until she finds out what they think about abhumans.

And then there’s Jaune, oh my Emperor is he dense. That scene was hilarious.

Ayy some Kriegsmen are around too hope we see them in combat soon.

Why was Deathwatch sent to go purge a Chaos Sorcerer? Their whole shtick is to slaughter Xenos with the utmost EXTREME PREJUDICE. If the Sorcerer was a Xenos, then I would be more understanding but from the sound of things he was human, so it’s a little confusing to me why Caim and his buddies were sent to off the heretical bastard and his followers
