Per 
Interview 1:
Dr: SCP (TBD)-4, please state your name for the record.
-Interference and audio warping-
Dr: Hm, alright, we'll do this the old fashioned way. For each answer you provide, I'll "translate" your response for the recording. This will be slower than natural communication; is that all right?
-More inerference-
Dr: Alright, let's try this again. As before, your name.
T: You may call me Alfred.
Dr: A strangely, er, normal moniker, by our standards at least.
A: My kind communicates through a chromataphors and telepathy, though the word you have for it isn't quite right. Names to us are not translatable directly. "Alfred" has a good match to my name, as much as a color can match a sound.
Dr: Interesting. How did you get here? You're rather obviously not from this star system, much less terrestrial.
A: Your deduction is correct, however you think only in terms of physical space. We come from another page.
Dr: I think there's that language barrier again. Can you elaborate?
A: You have a term, "extra-dimensional." While this has some aspects that convey the correct denotation, the connotation is that this is a seperate reality of some sort, or even a "higher plane". I use "page" as, although we are on different realities, they are all part of the same whole, the same "book" of existences that have the same general physics. If either of us were to venture outside of our book to another, we would not survive a fraction of a moment.
Dr: That's quite the revelation. How did you discover these so called "pages" and "books"?
A: To keep it brief for the sake of your time, we had theoretical scientists postulate this long before we came close to any of the technology to prove it, much less explore.
-There is a pause-
Dr: Yes?
A: We were too curious. We found something. And in turn, it found us. Or rather, it came back with us in the return trip.
Dr: I'm guessing you came here to escape?
A: Not at first. We tried many other pages first in an effort to shake this threat off. It was a predator, the likes of which we had never seen before. It was only when we arrived at this page that it was finally, definitively gone.
Dr: Our recon team and subsequent quarantine has confirmed this; you and your crew were the only ones we found, living or technological.
A: We would have not even risked your system if there was a chance the threat was not gone. Your measures were superfluous, but understood and appreciated for their earnest nature.
Dr: We have the who and the why, but you seemed to have skipped over the how. How do your ships work so that they are able to travel pages?
A: I am afraid it is currently impossible for your kind.
Dr: Is there a tech threshold?
-another long pause-
A: In a way, yes.
Dr: You took a while to answer that.
A: It is a complex one. Perhaps the most important thing your kind must accomplish is "world peace". Not so much complete peace, as such a thing is folly with the individual, but a global mind. Pulling in one direction in most things rather than the chaos it is now.
Dr: Ah. Yeah, that's fair. What else is necessary, if we achieve this?
A: I cannot say more.
Dr: Can't or won't?
-silence again, this time ending the conversation-
Interview 2:
Dr: SCP (TBD)-19, your "name" for the record, please?
T: I think "Okoye" sounds good.
Dr: …Well, that's what I get for having a movie night before an interview with a telepathic alien.
O: That part is untrue.
Dr: You're not a telepathic alien?
O: -audio distortion- The previous leader misled you. For your protection, in his reasoning. I believe you are made of stronger stuff than they believed. You deserve to have the truth, without obfuscation.
Dr: OK, so… How are we communicating right now?
O: The 'telepathic' part is true enough, at least as far as communication with humans is necessary. But we are not alien.
Dr: No offense, but we've never really seen anything on Earth like you. In fact, you couldn't have existed here without your ventilators.
O: This stems from another untruth "Alfred" told you; the "pages" and "books" fallacy was to hide that our ships are not trans-dimensional; they are trans-temporal.
Dr: … You come from another time period.
O: Correct.
Dr: How far forward? Or back? Relative to now?
O: Very far forward. VERY far forward. By 30 million years. From this planet.
Dr: Are humans extinct?
O: No. You are our ancestors.
Dr: I don't follow. The need for different air makes sense as far as climate goes, but if you resemble anything, it's a chephalopod.
O: You are already experimenting with gene correction. CRISPR is the first step. It only takes five hundred years for old laws against chimeras are overturned. It was far more practical to change the body than make accommodations for it for various environments and exploration.
Dr: Is this how everyone looks now?
O: Somewhat, at least as far as telepathy goes. The chromatophores are effective for communication when telepathy is difficult, such as addressing multiple individuals. There are heavy-worlders that have dense bone structure and strong musculature, light-worlders that are very tall and have longer lifespans, even dense-atmosphere-worlders with wings and two hearts.
Dr: Heh, we finally fly.
O: It was a popular choice when first made available. Now flight is seen as no more special than sharp senses or high endurance.
Dr: It sounds like a golden age.
O: It was… Though our genetic structure varied so wildly we no longer shared the same genus, we maintained reproduction through the same methods that led to that diversity. Population control was perfected, evolution turned on its head, and we ruined the Earth with our initial attempts to make it a garden.
Dr: I'm sorry to hear that.
O: We were in far-flung star systems by then, so it only really affected us as far as sentimentality goes. After a few more centuries, we were able to restore the climate and ecosystems and food webs therein. As an act of atonement, it was the first of our reserve worlds; dedicated to biodiversity and respect to what gave us our beginning.
Dr: How poetic.
O: To forget our past is to make the same mistakes.
Dr: Not quite the quote, but close enough.
O: Much literature was unfortunately lost to time, usually through poor record keeping.
Dr: -a short laugh- Somethings never change.
O: It seems so. After all, we're only human.
Dr: … I'm getting off track. OK, so, NOT aliens from another form of dimension, but human descendants from the distant future. As far as current space-time theories go, that makes a bit more sense. There's still one big question though; why did you come back here? What happened?
O: -a moment of silence- Your neurons seem strong enough for the shock. My ship contains the very last of our kind.
Dr: Excuse me? How?
O: We did not properly anticipate that there might be another intelligence in the vastness of the galaxy. You are familiar with… What was it called… A paradox of how old the universe is and yet no other beings seemed to spring from it.
Dr: The Fermi Paradox.
O: Yes, that one. I must apologize; that was a failing of my own memory.
Dr: Happens to the best of us.
O: We had forgotten any thought of meeting other civilizations that were not rooted from Earth. While we occasionally found life, it was often prehistoric, by your scale. These were marked as reserves for observation and sampling, and we moved on. We failed to see the pattern until we made a startling discovery on a planet light years away. A fossil of Pikaia gracilens.
Dr: Wait… That's a Cambrian fossil… That's…
O: Terrestrial, correct. We were as astonished as you are. But we were blind with excitement, placing all kinds of observation camps around that planet instead of preparing for whatever brought it there. The more we looked for fossils like this, the more we found, like a treasure trove buried just two feet under our garden.
Dr: Did you find out what put them there?
-heavy distortion-
O: I've met one. Face to face. They are… Beyond what I can describe without giving you a flash.
Dr: A flash?
O: It would imprint the image into your mind, etch it into your very neurotransmitters as if you had seen it yourself. I do not wish to cause you accidental harm as I am unsure if your mind could handle it without serious damage.
Dr: We will provide a D-Class with artistic proficiency after this.
O: Your practicality is a touch hubristic, but this information needs to be conveyed. I accept your offer.
Dr: We'll skip descriptions for now, then. How did you encounter this other?
O: They called themselves "Ix", but demanded we address them as gods. With the command they held over genetic manipulation, I imagine many from this time would call them such. Their mastery made our own accomplishments a child's finger painting against the likes of Michelangelo and Van Gogh. And their creations varied just as much if not more.
Dr: Was all of their tech like this?
O: It was biotechnology on a scale we could barely fathom. Living tools, fashioned for such a narrow niche that no doubt mass extinctions of them occurred with the changing of fashions. And we… we were no more than minks. Wild. Temperamental. Needlessly caught up in our own pursuits when we were destined to be material to be processed and used.
Dr: They changed you.
O: Like clay. Like plastic in a mold. I…
Dr: I can feel it, the rage and fear. It's ok. Take your time.
O: -silence and strong audio warping for about a minute before quiet- I saw the process in person. One of my family was used as an example. They were warped into a so-called "art piece". The pain I felt from them… There was no dulling of senses for them. Whole worlds were either mercifully destroyed or cruelly picked over and changed to fit the desires of the Ix. We had to escape.
Dr: How did you come across this time-jumping technology?
O: It isn't time alone; it's space. Thanks to our thinkers, and their genetic disposition pointed towards maximum brain efficiency and power, we were able to make the calculations necessary to slip through. All we needed was a good ship in strength and speed, a crew with nerves of steel, and a black hole.
Dr: You went THROUGH a BLACK HOLE?
O: Oh no, not through it. We utilized the Penrose Process; used one to, what's the term, slingshot.
Dr: You're kidding me.
O: I'm here.
Dr: My God…
O: Indeed. In order to allow a clean shot, we had to approach at the correct angle and speed, then release a payload that would simultaneously push us out of the spiral towards the Event Horizon and the payload directly into it.
Dr: I… don't see how that would work.
O: I forgot to mention an important detail. Apologies. You can probably guess that a star-hopping civilization would require enormous amounts of power. For that, we harvest black holes.
Dr: Wait, I think I know this one. That's when you build a series of reflective surfaces to make something like a Dyson Sphere. All you have to do is put in energy, close the sphere and let energy radiation build on its own.
O: You already know what happens if that energy isn't harvested, if it's left to build.
Dr: Like popcorn.
O: The Ix knew this immediately, though they sped up the process for a few select systems they didn't care to keep. They saw it as a spectacle. A show. Even recorded the moment life extinguished on the planets they eliminated.
Dr: You were toys.
O: There was one left, a big one. Many were lost in the mission, some acquiring the security codes to open the damned thing, some from placing themselves on site to keep it open long enough for us to complete a circuit and shoot back out, others still were too fragile from the acceleration or the warping of the Ergosphere. The fact that as many of us made it as we did, and more so that the Ix seem to have lost interest in those of us that got away… Well, it's enough to make one turn to religion again.
Dr: …Are you sure you weren't followed?
O: Either I would stop existing as we talk because the Au would soon be in this timeline, or you would see them for yourself. They aren't the subtle type.
Dr: "Gods," right.
O: As much as I would like to say otherwise, we didn't come back in time to simply escape them. We came to warn you. Warn… us. We didn't bring much with us, as we needed to keep weight and size as far down as possible, but we remember and know much.
Dr: You're offering us futuristic technology?
O: Not so much the technology itself as how we learned to make it, how to use it. The principles and laws of nature. The timeline we've left is no longer home, and we can do nothing more for it. The previous leader was hesitant to reveal the full truth for fear of sending you into a panic, but I have more hope. If you do not eliminate yourselves in this timeline, we can give your advancement a jump start. Consider us as a catalyst.
Dr: More like a deus ex machina.
O: I couldn't have put it better myself.
