SCP Foundation

• Yeah I'm planning on cutting down the testing. I've heard from multiple people that it just bogs the piece down, so I'll try to compress it.
• The scip is fully built and working as intended, so I didn't see a reason to have it be more complicated than necessary. I get your point though.
• If you're talking about the four paragraphs describing 0-3, then that was just supposed to be the results of the tests. If you're talking about the first and maybe also the second incident, then I see what you are saying. The first incident was supposed to be a feeling-the-waters type test since they didn't really expect anything different than the previous tests. The second incident was supposed to be their best foot forward for the setting of 5 since they didn't want to repeat the first incident. I'll see if I can make them appear more scientific and plausible.
• I'll try to explain more of what I was planning since I didn't really explain any of it in the article itself. So while members of the Foundation did build the five astral projectors, they weren't exactly loyal Foundation researchers. The idea I have right now is that they were Fithists from a previous Star Signals event back in 1951 that managed to stay undetected. They built a machine that would allow them to become informational entities, similar to what members of Ará Orún are. The setting of 4 has the instance/occupant act as an anchor for themselves, but this limits how much they are able to accomplish. The setting of 5 discards this anchor in exchange for allowing the occupant to permanently become an informational entity that exists solely in the noosphere (I think I'm using your own terminology correctly, please feel free to correct me on any mistakes). The Fifthists used the scip to turn themselves into informational entities to submit themselves to SCP-3125, basically. That's why they didn't leave a manual behind. They never intended for anyone else to ever find the scip. They also placed some form of antimemetic protection over the containment cell that prevented anyone from learning about it, but after 50 or so years the protection failed and the Foundation discovered it. (I'll admit that I haven't read much about the Fifthism GOI, so let me know if this sounds completly out-of-character for any possible Fifthist sect.)
• When I was writing it I forgot to include the Foundation insignia the first time around, so I'll try to go back and rewrite it so I don't gloss over it. I figured that researchers would want to elaborate fully on what each setting does, but I realize that was appealing more to the format rather than the story.
• I'll talk about the task force name in a second, but as for the character name, I didn't really think much of it. It was just a random name I picked out a while ago, so I have no problem with changing it to something that sounds better. I get your point about devoting an entire paragraph to a character that has very little background instead of explaining the task force name, but I'm not sure how I can change that besides just cutting a lot of it out.
• Honestly, the in-universe justification behind also choosing Omega-Zero is pretty much just a coincidence, unless you want to believe some fate-affecting entity is pulling the strings. Both Omega-Zero task forces don't know of each other (I'll explain that one too in a bit), but the reason I chose Omega-Zero is partially because having two task forces with the same name that don't know of each other parallels having two divisions with similar purposes that don't know of each other and partially because it would help readers recognize the similarities between 2111 and this scip. Although I did have one critter point out the task force name was already taken without realizing it was intentional. Also, I didn't realize that Omicron-Rho was similar, so I'll try to do a little reading about them.
• I actually hadn't even realized that all of the codenames had the initials RT. That's a cool detail.
• I was planning on writing a tale about the second incident from the perspective of the task force on the astral plane, but I'm thinking that I might just add it in at the end of the article in a note that's only viewable to members of the task force while in the astral plane. That's partially because the article doesn't really have a satisfying ending and partially because I suck at writing tales.
• So the reason neither Omega-Zero task force can't perceive each other is due to the fact that Site-5, the site this scip is contained in, doesn't exist. That's also the reason why anyone using the scip can't leave the site. The entire Site-5 is isolated from the rest of the Foundation, with anyone outside of it not knowing it exists and anyone inside of it not knowing no one else knows it exists, basically. While it's a similar effect to what happened to Site-41, I haven't decided whether this effect is on purpose or accidental. Edit: I realize that this bit is probably confusing since antimemes don't have the same effect on informational constructs as they do on physical beings, but just think of it as something around Site-5 is restricting the noosphere in a way that isolates Site-5 from the rest of the world. It doesn't fully stop the transfer of information, but it makes it near impossible for information to flow into and out of it, sorta like how pinching a hose never fully stops water from coming out.
• I haven't actually heard of the ziggurat. If it exists somewhere in the physical world, then most likely not due to it being outside of Site-5.
• Well, if the effects of Site-5 didn't exist and SCP-3125 didn't "eat" them as soon as they became anchorless informational entities, then they could possibly contact the other Omega-Zero. Hopefully I explained it well enough above, but in case I didn't, the setting of 5 turns them into essentially saints minus their anchor, since no one in Site-5 has access to or knowledge about mnestics. However, even Site-5's antimemetic defense can't protect the informational entities from 3125. Also, the reason that everyone but the last member dies is because the last member realized what was going on and killed the other four member's bodies. This was to prevent SCP-3125 from overwriting their memoeme and using them as a puppet. The last member also managed to disconnect himself before his instance got set to 5 to prevent him from losing his anchor and getting "eaten" by 3125.
• If it was either of the two, then most likely Counterconceptual. However, since the scip was made sometime between 1951 and 2018, a different, third antimemetic-based division could have been behind it. This could also support how no one knows of Site-5, as the antimemetic shield could have been put in place to prevent SCP-3125 from destroying the site/division like it did to the majority of antimemetic research groups.
• Since the scip was meant to help the Fifthists transcend to the astral plane, they wouldn't have much of a reason to leave behind a manual. Everyone that was a Fifthist would have used the scip to transcend, so anyone left wouldn't have a good use for the scip besides potentially researching and reverse-engineering it, which is exactly what the Fifthists don't want.
• I see what you are saying about how this is basically Ará Orún but living, but that was never my intention. I originally had the idea about the sleeping pods that let you become ghosts similar to the current Omega-Zero, and then I started thinking about Fifthism and Site-5 and it sorta snowballed from there. I guess having the Dreamwalkers opens up a few interesting story options, since both the astral projections of them and the physical versions of them can exist at the same time, but any communication is one-way. Perhaps in the future I could write some tales or scips that bridge the gap between this Omega-Zero and Ará Orún, but right now there aren't any definite plans to.
• (Also, I know this is a really minor note, but I used the capital omega in the abbreviation to help differentiate between the two. Although I do realize now that the capital omega is also used in coat of arms on your author page, so that might just add to the confusion.)

• I'll try to work on that. The last thing I want is for readers to feel so overwhelmed and confused that they lose interest.
• This is probably one of the things that I'm going to have the most difficulty with. I'm not sure I'll be able to have any payoff given that neither task force knows or, at this point at least, can know about each other.
• Yeah, I'm definitely going to try to add a PoV from inside the astral plane, probably in the form of a note that can only be read from inside the astral plane that details their mission and maybe explains the second incident. I'll think about it a bit more since I don't want readers to feel like there wasn't a payoff at the end of the article.

Thanks for the feedback! Sorry if it seemed like I was trying to one-up what you have already or impose my ideas on your own. If there's any other suggestions or problems you have with what I have right now, feel free to point them out. Hopefully what I wrote down makes sense and helps explain away any inconsistencies. Also, let me know if I used any of the terminology incorrectly since I should probably get in a habit of learning them to help prevent any further plot holes or inconsistencies.
