Okay, first I'm gonna say that the concept was really fun. Reminds me of one of my OCs actually. The dynamic between the two civilization is really interesting and reminds of of that bigfoot SCP kinda.
However, I find the execution of the concept too lackluster at the moment.
My main issue is about how the page has been developed and written. It reads like a synopsis more than an actual story/flashback. The overall flow of events if simply thrown out to the reader without much else to really feel the story. Let's take the following paragraph for instance:
You see, one of our key flaws is that for all the wonders we can do, we cannot create. We can travel, we can extend lives, but to create something from nothing is impossible for us. We are creatures of reality; we reflect what is and what was. It is like… being actors in a play. The actors interact, but the lines have already been written. There is no deviation from the script. We were nothing more than fancy automatons of reality. An existence that had one singular purpose, with no capability for change or growth.
Here, you tell us directly what the deal is with this species. You also tell us about their feelings somewhat, but this is just telling. While it makes sense in this storytelling, the text lacks clear consequences. While you tell us they can't create, you don't show us how they tried and found out, how this influenced their life… Does this mean they can't reproduce for example? This paragraph alone is lacking a lot of development to make it interesting. It sounds much more like a funfact, and not something that takes my attention because it feels so disconnected from the overall story. With only facts thrown at us like a history book, the tone feels very artificial. It doesn't seem like it's Herne talking, as he's remaining very close to the surface of the story.
The other issue I have with the page is how devoid of the actual character it is. The entire article just feels like it's narrating the story of the species. It frankly would make more sense as a tale, or as an offset of the wild hunt article. Herne is barely presenting himself or even stating his emotions and point of view (something I talked about earlier too). He talks about the species as a whole, but almost never about himself. The only time he really talks about him and only him is in the "I remember the first time I became able to hold a spear, the first time I donned armor" paragraph, which is quite ironic in his own POI page. While narration had the potential to indeed make the POI page more appealing to readers, here, the lack of personality of Herne and the absence of himself in his own story doesn't make me interested in him. And it's a shame, since the "Gentleman that can kill you" archetype is what you seem to go for, and it's my favorite trope when it comes down to characters in general (Bill Cipher, Alastor, The Beast of Level 5 Trazyn the infinite…), so quite a failed opportunity for a POI page.
There's also some minor comprehension difficulties I had, like when Herne implied the wild hunt knew humans before they first noclipped into the Backrooms. While I can most definitely see what it can imply, it's something that was quite weird at first.
Overall, while the two concepts of both character and setting are very interesting and promising in their own right, the excecution of the narrative devlopment, as well as the character representation, doesn't allow for me to upvote the article in itself, even if it uses themes I would otherwise enjoy. While you will maybe shrug off my opinion since I am not a short page enthusiast, I still believe that the fact you stayed so much on surface with the topic, keeping it on facts only with no real depth or devlopment, really hurt both the underused character and the story he tells us. It's even more infuriating when I see that in some rare paragraphs like in, again, the "I remember the first time I became able to hold a spear" one, you dived deep in not only the character, but also the implication of the events, which allowed me to get more interested in the subject. It's just a shame too much of the page feels like a history summary rather than a captivating tale told by an active character.
