SCP-4XXX
Object Class: Euclid
Special Containment Procedures: All known points of ingress to SCP-4XXX are to be actively monitored to prevent public access. Security stations have been set up at all known points of egress from SCP-4XXX. Anyone or anything exiting SCP-4XXX must be secured and transported to Site-53. Surveillance of SCP-4XXX must only be carried out via remote drone equipped with RxN camouflage. Contact with any member of SCP-4XXX-A is strictly forbidden.
Description: SCP4XXX is the town of Thistlebrook, Tennessee, population 918 (footnote as of the 1971 census). At some point in 1989, all outside contact with Thistlebrook ceased. Family members, friends, and local officials traveling to the former location of Thistlebrook found only a dense patch of forest. A small number of those who traveled into this forest went missing, prompting further panic. The site came under Foundation control shortly after. For additional information on the 2-Year “Thistlebrook Whiteout” project, including some 1300 amnestizations, public record tampering, and government intervention, see document 4XXX-A1-TBW.
Thistlebrook now exists in a dimensional pocket outside of mainline reality. How/why this was achieved is currently unknown. Humans inside this space are subject to SCP-4XXX-Alpha, a process that both alters and accelerates evolutionary adaptation. Based on their immediate surroundings and cultural memory, human groups will diverge into an entirely new sub-species of Homosapien. This process is so rapid that environments as small as a 37m2 apartment can provoke evolutionary changes I.E. reduction in size, nocturnal habits, territorialism, loss of social needs, etc.
SCP-4XXX is only accessible from 17 locations, the largest being the P28 roadway (demolished), and the smallest being a hollow stump on its south-eastern edge. In contrast, only 3 egress points have been found. These points can be identified by their visual cues. “Entrances” cause a slight air vacuum, and can be identified by a circular radius of cleared earth free of dry leaves, plant growth, etc. “Exits” will produce a small diffusion of water vapor around their outermost edges.
“Entrances” and “Exits” to SCP-4XXX are stationary, but only remain active for short span of time. As a result, remote observation has proven impossible over extended periods. Wireless transmissions fail inside SCP-4XXX, but with their limited window of opportunity, cable-fed drones have managed to relay some information.
On June 15th, 1991, MTF-Delta-7 “Planeswalkers” were dispatched to survey and assess SCP-4XXX. Agent Jaelyn Hart was the only member to return safely, with all others reported KIA. Most existing information on SCP-4XXX has been derived from Agent Hart’s audio, and brief video recordings. No future expeditions are currently planned.
MTF-Delta-7 “Planeswalkers” Expedition Log, SCP-4XXX. June 29th, 1991.
MTF-Delta-7-3: Start. Test 21. Fuck this place. End.
MTF-Delta-7-3: That’s more like it! God, fucking finally. Alright. This is Agent Jaelyn Hart. The date is- Jesus, has it really only been two weeks? Alright, June 29th. The rest of the Planeswalkers are… well, shit, I suppose I should start from the beginning. This might be the only log left.
We entered SCP-4XXX a week ago from IP15. It was just… trees, forever. Thistlebrook is sort of at the top of a hill, so without any obstructions I could see for miles. The forest never stops. I remember when we were driving down to the site, Jackson-… god, fuck. Hold on.
Audio is reduced for 8.3 seconds. Agent Hart is heard sniffing, followed by three slapping sounds. Away from the microphone, Agent Hart is heard saying “Get it together Jaelyn. We’ve got shit to do!”
Right. Planeswalker-4 was pointing out landmarks in what he called “cowshit country”. I can see those same set of hills due East. Except there’s no cell towers on these ones. Just trees. The stars are the same too, I think. I’ve never been much for astronomy, but the Big Dipper is still North.
We set up base camp on the far edge of town, did some perimeter and recon sweeps. It’s… I don’t know, gently apocalyptic? I mean, everything is overgrown and nothings working but… that’s it. No bodies, no fires, all the buildings are in pretty good shape. Hell, there isn’t even that many broken windows.
We ran into the natives almost immediately. Looking back, it was unlucky we found the “Shuckers” first. They’re pretty passive. It gave us a bad frame of reference for the rest of-
Agent Hart goes quiet for a period of six seconds. Slight crackling and thumping is picked up.
Fuck. I’m hoping that’s just some “Juvies” fucking around, but it might be the “Fuzz”. I’ll pick this up in the morning.

MTF-Delta-7 “Planeswalkers” Expedition Log, SCP-4XXX. June 30th, 1991.
Log begins with several seconds of footsteps, birds chirping, and hard breathing.
MTF-Delta-7-3: I’m on the move. The bakery isn’t safe during the day. Too exposed.
Agent Hart is heard eating something crunchy, followed by several gulps of liquid.
MTF-Delta-7-3: I’m also going to need more supplies. A few “Juvies” told me how to get them, but honestly, you’re rolling the fucking dice with those guys… let me back up.
It’s Planet of the Apes in here. Sort of. The best way I can describe it is… it’s like evolution took three steps back, then one wonky leap forward. The good people of Thistlebrook got all hunched over and hairy, but then they “re-evolved”. Now everyone’s super selectively adapted. Over-adapted, honestly.
Those “Shuckers” I mentioned? Former farmers. Now they’re tall, creepy, squinty-eyed fuckers with freakishly huge hands. They’ll leave you alone, but only if you don’t try and pick the corn. Learned that the hard way.
The “Juvies” are what happened to the local teens, I’m guessing. They still wear torn up hoodies and pierce themselves with clothes pins and fish hooks. They’re like big spider monkeys. Fast, lanky, and foul mouthed. Hah! Yep. I can see a group of them swinging on the street lamps about a block down.
Agent Hart goes silent for 16 seconds. In the distance, the sound of hooting and high-pitched laughter is heard. Isolated samples of conversation are later extracted. “Thwipit greener!” “I thwip! Nasty J! No grip!” “H-bod! H-bod! Get grip!”
Cheeky fuckers. I’d say they’re my only friends in here, but honestly, I think I’m just a novelty. They’d probably toss me to the “Fuzz” for a laugh.
They’ve still been a big help getting th- shit! Hold on.
Agent Hart is heard running briefly, climbing a chain link fence, then landing on the other side. When she begins speaking again, her voice is hushed, and close to the microphone.
MTF-Delta-7-3: Damn it. Speak of the fucking devils.
For a period of 34 seconds, the sound of stomping, scraping, and ape-like grunts are heard growing louder, then progressively quieter.
MTF-Delta-7-3: Those assholes are early today. The “Fuzz” are what’s left of the Thistlebrook police department. State troopers too, I think. Think double-sized gorillas. I killed one a few days ago.
Agent Hart remains silent for another 12 seconds, breathing slightly more erratically.
MTF-Delta-7-3: Didn’t even have my gun. I had to do it with a kitchen knife. Snuck right up on the fucker and just-…
The recorder is muted for a period of several minutes, then turned back on.
MTF-Delta-7-3: … They got us on night 5.
Agent Hart is heard forcing a door closed, and closing a set of curtains.
MTF-Delta-7-3: 10 charged us down the street while we got flanked on both sides by another 8. Classic “bull horns” tactic. They circled us before we could even get our guns up. Not that it mattered. I think we downed… 2, tops. They’re just too fucking big, and they were using car doors as shields. Dan- god, fucking, fuck! Planeswalker-1 went down first. They’d been watching us, they knew he was in charge. They just … threw him into a wall, and that was it. Planeswalker 2 and 4 were disarmed, by which I mean those monsters stopped just short of beating them to death. I-…
Agent Hart goes silent for ten seconds. The recording device is heard shaking.
MTF-Delta-7-3: No. Jaelyn, we’re not shutting down. You hear me? We’re not shutting down. We’re going to make it right.
The sound of several items being stowed into a bag or pack is heard.
MTF-Delta-7-3: I’m heading “Downtown” now. It’s where they take their captives, apparently. Likely a police station, or jail or some kind. Nat and Isiah might still be alive… shit, I mean-… know what, fuck it. This isn’t a rescue op. I’m not following protocol. This is a suicide mission hedging on the very, very slim chance my friends are still alive and I am owning it.
MTF-Delta-7 “Planeswalkers” Expedition Log, SCP-4XXX. June 30, 1991. 2.
Log begins halfway into a conversation between Agent Hart and another entity identified as an SCP-4XXX-A4, aka “Juvie”. This creature speaks in a somewhat chirping voice, with hiccup-like pauses on words with a hard “J”. “D” sounds are stressed, and loudened.
MTF-Delta-7-3: Greeners aint on drive?
SCP-4XXX-A4: All parked! No thwip! Dine and dash! Dine and dash!
MTF-Delta-7-3: And they won’t… fuck- they wont.
SCP-4XXX-A4: Fuckers fuckin fuck!
MTF-Delta-7-3: Cram it. Greeners won’t chase? They won’t-… harsh like the Fuzz?
SCP-4XXX-A4: Greeners harsh in the mart. In the J-ungle they aint on drive. All stock store specials! No thwip!
MTF-Delta-7-3: Alright. I’m trusting you here buddy.
Agent Hart is walking. The SCP-4XXX-A4 continues speaking as she grows farther away.
SCP-4XXX-A4: Buddyobuddy! Learn a thwip! Learn a bend ground thing! A tall J keeps Fuzz away!
SCP-4XXX-A4 then gives a barking laugh before being heard swinging away.
MTF-Delta-7-3: I’m calling that one Sid. Sorta’ looks like the guy from the Sex Pistols. He’s my favorite. The Juvies have their own sort of dialect. All the dash-A’s do. Seems like culture and idioms diverged just as quickly as everything else.
Agent Hart is heard laughing to herself as she walks, moving slowly, brushing against surfaces constantly, implying she is moving through alleys and confined spaces to avoid the main streets.
MTF-Delta-7-3: I’m going- we’re going to need more supplies if we’re going to walk out of here. There’s plants and bugs practically everywhere, but one of the first lessons you learn in the Planeswalkers is “Don’t snack outside your reality”. Who knows, whatever monkey-fied everything might be in the water. I’m not taking that risk. Sid told me Dan’s supplies- Planeswalker-1’s supplies were traded to a group called the “Greens”. They operate out of the local grocery store, one of those out-of-place giant Wallmart sorta’ places you always find in small towns.
Agent Hart stops in her tracks, makes a little hissing sound, but then is heard laughing again.
MTF-Delta-7-3: Hah! I just spotted a “Homebody” crossing the street. Brave little fucker. They’re about three feet high… maybe four, they’re always so curled up, even when they move. Huge, round eyes. Like-… fuck, what are those things called-. Shit there was a youtube video ab- slow loris! That’s it. They look like big, dark-furred slow loris…ses. They mostly stay inside their own homes, hence the name. They sneak out now and again to grab supplies, or go to other houses to-… well, I can only guess, “socialize”. Gotta make more monkeys somehow. I tried to make a new home-base in a little two-story at the end of a cul-de-sac a while back, one of those things scratched me up good. They’re skittish, territorial, and deathly afraid of the Fuzz. You’ll never spot one outside after dark. You’ll always see their eyes though, peering at you from the windows, under garage doors, over fences…
Agent Hart makes a verbal sound of disgust
MTF-Delta-7-3: Not to be confused with the “Hivebodies” on the west end of town. They’re the guys in those three apartment buildings, and the retirement home. They’re a bit more social, smaller, and have more richly coloured-…
Agent Hart stops speaking for 15 seconds, then audibly sighs.
MTF-Delta-7-3: This is why I signed up, you know? I worked so hard to get promoted to Agent. I wanted this. I grew up watching “Star Trek” and listening to my grandpa’s old serials. I wanted to be an explorer, discover alien life. I love this, and I hate myself for loving this. My team mates might be dead. I might be dead soon too.
