I'm still not sure who the fucks eyes this story is being told through

Have Yang say the first thing that pops into her head? Yeah, that sounds accurate.

This is one of those stories who u find at the bottom of a favorites list and wish it got more attention since it might have inspired the writer to write more.

First: good story! However, you seem to be hammering everyone like a bash-fic. I'm not fond of your interpretation of Aura, but it fits together well. It seems like you want RWBY to be Warhammerish Military, or straight-up killers instead of what they are. I think killing is a necessary part of their job, but not a part that should overwhelm everything else,

I love this. The twisty messing with tenses, the hiding of the protagonist's identity, the musing on the mental damage of the main characters… everything. Honestly, it isn't exactly well-written, by conventional standards, but it it's unconventionality outweighs that utterly. This is a story that goes in five different directions, is bursting with creativity… something like it comes along very rarely. I hope you continue it.

After reading all available chapters over this last week, here's my overall review of this surprisingly lowly seen fic.

The good:
Takes 'suspension of disbelief' territory of canon and examines why these things might be (lack of universal aura unlocking, personal construction of weapons, only see 3 teams completed, mortality rates, support gear, non reaction to bullies on staff's part) and then tries to run with them as far as possible. And then has the 'exposition target' that was used react in (mostly) IC and logical ways to this new knowledge.
Uses Fantastic Racism as a lens to examine modern prejudices (not explicitly, but the term 'passing' is used more than once). YMMV, but it got me to think differently a few times (on both sides of the 'fence', that of the true 'phobe and the side of equality).
A 'Peggy Sue' that, despite being started well before some of the heavier 'Canon' of RWBY was released, does a decent job avoiding being cornered by those reveals and manages to incorporate them eventually.
The combo first/second perspective is different and weird, but an interesting experience that slowly makes more sense at it went along.
As of the first 20 chapters, there's no blatant shipping to distract from the plot. I don't count flirting or jokes (though YMMV, if you want a ship fic there's thousands of others to choose from).
This is not a SI fic. The PoV characters are canon and explicitly revealed before the end of the first 'volume'.

The Yet Another factors, so potentially annoying but on a YMMV basis:
Y.A. Peggy Sue trying to stay close to OTL
Y.A. PoV character trying to fix everything
Y.A. PoV keeping secrets from Dumbledore
Y.A. friendly series given the grim and gritty 'realism' filter
Y.A. PoV training their favorite canon characters
Y.A. super special powers that I can teach, but nobody else uses/can use/should use
There's more, but these are the ones that follow the crux of the story the most.

The Bad:
Some of the 'suspension of disbelief' fillers I mentioned before are dry to read. Usually they're exposed in a discussion format, but at least once the editing has left the explanation in twice and it was like reading a filler lore book for any other work of fiction the first time. Not terrible, maybe necessary, but a little boring.
It maybe could use another editing pass. The aforementioned repeat of an explanation might be an artifact of the PoV experimentation (I could also be dumb and not understand the differences between the two), but I recall at least twice thinking "Didn't I just read this argument/lecture?". At least the grammar and spelling is consistent enough that I never noticed a problem (not even once, but I wasn't looking for any). There's also a typo/mispelling of the PoV's name that put me on the right trail of the true identity; the surprise might have gotten me otherwise.
Before I realized this wasn't an SI, I thought it was going a path I'd seen multiple times, and I mention in the Y.A section. Character inserted into story, they decide to fix problems of OTL, they can't get everybody in on the plan because of some reason or another, they have some magic/weird/special/MarySue ability to help this time, they train canon characters into almost entirely different beings. That fear reduced by chapter 10, when I'd seen enough IC moments for the canon characters, and non-SI traits of the PoV characters, but it remained a specter the entire time and is definitely my least favorite part of an otherwise enjoyable experience.

TLDR: A Peggy-Sue style fic staring two characters trying to prevent a terrible future by improving the abilities of both their past selves and of their friends. Contains a large helping of speculative, low level world building and a portion of gritty realism.

I enjoyed it, and I'm surprised a fic this old and this good doesn't have more publicly available readership stats.

You appear to have lost a section, Ruby goes from speaking to Glynda to looking at her team's scrolls with them present with nothing in between.

It pains me when gravitational lensing is cited as something destructive. It really does.

Question, is the OC Augustus Black named after Captain Black from the Jackie Chan Adventures cartoon? 'Cause they do have the same name.

Well, honestly Blake would have been my last guess, if only because of the lack of her ears, should have picked up on the first reference to the scars on her scalp the first time. I'd figured either Yang or Weiss, not sure why.

Dang, I guess Professor Blake is in the house. And here I was hoping the name was a red herring.

Yang though? O.o

It certainly gotten interesting. It's basically Sarah Connor trying to prevent Judgement Day, while Salem laughs in the background at mankind's hubris.

Damnit, you really screwed up big time didn't you Ironwood.

I think you posted a chapter for your worm story by accident.

What the hell? This is a chapter for a Worm fic, not the RWBY fic here? What is going on?

For a writing experiment this is actually pretty decent stuff. Your prose is relatively mature and easy to read. There's hardly any grammatical or spelling errors that I can see, which shows that you actually care enough to review your work before posting it. Too many "writers" on this site like to write stream of consciousness garbage before putting it up and expecting kudos for it.

Keep up the good work, and I look forward towards the next chapter.
