[BEGIN LOG]
[The footage begins in a dense forest during light rainfall. The camera is attached to the helmet of Om-1 who is surrounded by three other ATF operatives.]
Om-1: Call out. Om-1, reporting.
Om-2: Om-2, reporting.
Om-3: Om-3, reporting.
Om-4: Om-4, reporting.
Om-1: Alright, let's head out. Move in.
[Task force begins to head in the direction of the reported anomalous phenomena. Agent movement continues for approximately thirty-seven seconds before a loud crunch is heard.]
Om-2: What in—
Om-1: It’s just leaves. Keep moving.
Om-4: Sorry to break it to you, but it is most certainly not just leaves.
[Om-1 looks down at the ground below Om-2 to spot an unusually large centipede which is clearly deceased. A large portion of its body has been crushed and an unnaturally-colored liquid substance leaked out of the crushed portion.]
Om-2: Christ, that’s disgusting.
Om-1: Keep moving.
[A portion of irrelevant dialogue has been removed. Fast forward forty-one seconds. The task force is advancing towards the reported location.]
[A large swooping sound accompanied by hissing is heard from above Om-1 before the sound abruptly halts.]
Om-3: Contact! That thing was huge. Above us, in the treeline.
[All agents raise their weapons, looking up into the treeline. No movement or abnormal objects are seen.]
Om-1: What was that?
Om-3: I don’t know. Some kinda… centipede? But the damn thing had wings half as big as me.
Om-1: Copy. Let’s keep moving.
[The task force advances once again. No dialogue nor any significant events occur until a partially-obstructed building with a main portion and two wings, one extending from each side, comes into view. The units crouch down and aim their weapons at the building.]
Om-1: That’s our target. Scan for movement.
Om-4: It… it looks like the whole thing is moving.
Om-2: What?
Om-4: The walls of the building. They’re shifting or something.
[The headcam of Om-1 enhances focus on the building to reveal portions which appear to be in movement, shifting autonomously from its surrounding portions.]
Om-1: That's… not the wall moving.
[Om-1 quickly holsters his weapon, taking out a flare which he lights and throws it at the wall of the building. The flare bounces off the wall as multiple arachnid and insectoid entities fall off onto the ground. The flare improves the visibility of the building, showing the source of the movement to be a thick swarm of arachnids and insectoids.]
Om-2: Oh, my god, I think I’m going to vomit.
Om-1: We’re not here to be scared of the damn thing because it’s covered in spiders or centipedes or whatever the hell those things are. We’re here to get in, survey for anomalies, and get out. Let’s make this as quick and efficient as possible.
Om-2: I don’t—
Om-1: Listen. If you want to stay right outside, then be my fucking guest. But you’re only making it harder for the rest of us to complete the mission. So I’d suggest you grow some balls and come in with us.
Om-2: [Hesitantly] Alright. Sorry.
Om-1: Don’t apologize. Let’s move.
[Om-1 takes out his primary weapon once more and lights another flare before approaching the right side of the wall. As the agents move, the swarm parts away from the light, creating a path of visibility. Om-1 soon spots a door to the building.]
Om-1: Stack up.
[The agents proceed to the door utilizing standard breaching procedure, concluding with the agents kick down the door, entering the building. A thick, loudly buzzing swarm of flying insects emerges from the breach, obscuring camera feed for 6 seconds before dispersing to the point that audio and video feed are coherent.]
Om-2: Fuc— [Retching.]
Om-1: What the hell…
[Interior walls are crawling with a thick layer of various arachnids and insectoids. Units slowly enter, with the swarm continuing to part around the flare light. Two hallways lead to the eastern and western wings. A staircase to the basement is visible.]
Om-1: Alright, team, western wing first. Remain on me.
[Units proceed down the western corridor for several seconds before a hissing noise is briefly audible over the buzzing. Om-4, who is at the back of the line turns sharply towards the basement staircase.]
Om-4: The hell? You guys heard that right? That voice?
Om-3: Voice? No, just these damn buzzing wings.
Om-1: Keep moving, and keep your ears open if you hear it again.
[Units continue to the western wing, passing an infested washroom and supply closet before arriving at an open room with six chairs, four of which have heavily infested corpses resting on them. As Om-1 nears the center of the room, a thick mass of insects infesting an animal skin rug fails to withdraw from the flare light.]
Om-2: They don't wanna get off the rug? The rest of 'em don't seem to like light very much, what's up with these ones?
[Om-1 approaches the rug, allowing for sharper camera focus and revealing a near-constant stream of arthropods emerging from and withdrawing from the rug.]
Om-1: Oh hell, they just keep coming out of it. Om-2, crate this up and get it outside.
Om-3: We've got something else. This body's chest is humming.
[Camera feed turns to take in Om-3, nearing one of the corpses seated in a chair, reaching out and resting his hand on the body's upper chest before pulling a carved bone amulet from the corpse's neck. A winged insect resembling a large wasp partially emerges from the body's mouth.]
Om-3: It's like a… I dunno, it feels like there's a whole damn hive inside him.
Om-1: Careful not to disturb them. Om-3, light a flare and collect any other occult curiosities they collected in here. Om-4, you're with me.
[Om-1 and Om-4 return down the hallway towards the main lobby towards the eastern wing, passing through the main lobby. An audible hissing noise is heard briefly over the background hum.]
Om-4: There it is again. It's definitely coming from the basement.
Om-1: Light a flare and hold position here, keep listening, see if you can make any sense of it. I'll continue investigating the east wing.
[Camera feed continues down the eastern hallway, passing several taxidermied heads mounted to the wall. Arthropod infestation begins to thin during the final approach to the eastern wing, giving way to a carpet of thick kudzu-like plant overgrowth. Multiple dead arthropods are visible within the plant growth.]
[Om-1 coughs lightly, stepping onto the overgrowth and into the trophy room. Several corpses are visible entwined with the thick plant growth. Camera feed moves to take in the taxidermied head of a Sika deer with blue patterned fur, the patterns of which can be observed to shift slowly. Om-1 can be heard to cough more violently, causing camera feed to shake.]
[Om-1 moves towards the taxidermied head and struggles to remove it from the wall. Wheezing and nauseous groaning become audible, as Om-1 succeeds in dismounting the head, dropping to the ground alongside it, his breathing shallow and punctuated by wheezing. One minute and eighteen seconds elapse in this manner before footsteps can be heard approaching from the hallway along with faint flare light.]
Om-4: [Distant, approaching.] I went ahead and peeked down in the basement. Bugs are real thick down there, weren't scared of the light. Lots of millipedes. Kept sounding like something was calling out to me from inside, but I couldn't get a look inside, just managed a peek through this small hatch built into the door. Looked like some kind of wet meat, pulsing, like a heart. Bigass centipede lunged at me and I swear the fucker said my name, I think we shou… Sarge?
[Om-4 rushes into frame, lifting Om-1 over their shoulder and standing, coughing lightly as he withdraws with Om-1 from the room.
Om-4: Team, withdraw! Something's in the air in here, Om-1 is down. Get out of here, now!
Om-2, 3, and 4 subsequently returned to SCP-4810-A with self-contained respiration systems and collected remaining listed anomalies, along with the attached journal. SCP-4810-4 is successfully contained within SCP-4810-A. It is the official recommendation of ATF Omicron-77 that it should remain in such state until the nature of the anomaly is more fully understood.
