SCP-3417 - The Preachers of Globular Cluster Terzan 2

rating: 0+x

SCP-3417 X-ray emissions, recorded by the NASA High Energy Astronomy Observatory 2 in 1980. Each orange spot is a source of X-rays, with SCP-3417 being the brightest one.

Item #: SCP-3417

Object Class: Euclid

Special Containment Procedures: Scientific articles theorising SCP-3417 to be an X-ray pulsar will be published if astronomical groups become interested in the anomaly. Foundation assets in the field of astronomy will either prevent the development of or alter technology that could potentially decode the anomaly's X-ray emissions.

Monitoring probes NABU-1 through NABU-4 have been deployed by Autonomous Exploration Satellite Ehlers-001 (AES E-001), which will orbit SCP-3417 and record all X-ray emissions. These emissions will be decoded by Extrasolar Activities Division members and Ortothan Extraterrestrial Language translators.

Revision 1: Monitoring probes NABU-5 and NABU-6 have been deployed in orbit around SCP-3417-2. Following the recent allocation of funds for the exploration of Terzan 2, further probes to monitor any discovered SCP-3417 instances or locations of interest will be constructed.

Revision 2: Due to severe malfunctions in NABU-2 and NABU-3 from ionizing radiation and matter/antimatter annihilation, the probes have been replaced with NABU-7 and NABU-8.

Description: SCP-3417 is an organic extraterrestrial entity located near the center of the Terzan 2 Globular Cluster1, moving at a velocity of 205km/s.

The organism is approximately 40km long. The body is comprised of two cones of equal size, with the bases connected to a 4km long cylindrical midsection composed of organ and bone-like structures. Four tunnels placed at 90° intervals are present on the surface of the cones, which descend for 5km. The tunnels are suspected to extend for longer, though further exploration is impeded by a large mass of flesh present at the end of each one. The anomaly has a primarily red coloration, though various yellow circular patterns, scratches, and craters are on its surface.

Four 43km long structures (hereafter referred to as transmitters), composed of a mass of tendrils terminating in a spheroid object, radially extend from the midsection, located at 90° intervals. The transmitters produce X-rays with a frequency in the range of 16-17 EHz in periodic bursts, released in a spherical region around each spheroid. Analysis of the X-rays shows that their properties are modulated in a similar manner to radio wave communication, creating unique signals that can be converted into information when detected by a receiver.

These signals consist of static noise with abrupt changes in pitch. Analysis of the audio shows that each signal contains logograms from an unknown dialect of the Ortothan Extraterrestrial Language (OEL)2, which are only visible in spectrograms of the audio. The symbols are created with sudden decreases in the amplitude of the audio, and are arranged in a pattern of alternating diagonal lines. Each signal describes events related to Ortothan mythology3. Information on the Ortothan language and its dialects is limited, though portions of the transmissions have been translated. Excerpts are available below, with punctuation marks added for legibility.

Urkot-leusan4 said: "Why was the statue built?"

Priest tendril of [Unknown Symbol 29: a name?] screeched: "Eov-Leusan5 evaporated conqueror [Combined Symbols: Beast Ships?] with ascended cannons. My existence preserved by act. I am eternally grateful for such act. Build temple for Eov-Leusan. Yes?"

A (grid, array) of hundreds of [Unknown Symbol 29]'s tendrils were (bowing?) and (masticating?) by the statue and temple.

Urkot-leusan asked: "Do you know that I killed more conquerors than Eov-Leusan?"

Priest tendril of [Unknown Symbol 29] said: "Eov-Leusan did not say that. Eov-Leusan evaporated all."

Anger and jealously manifested in them. Eov-Leusan was not superior. Urkot-leusan (unsheathed?) their ascended swords and dismembered [Unknown Symbol 29] across the star system.

Above the city Zeyu-leusan's6 physical body manifested. The (spears?) were fired from the towers but were (punched?) in a burst of light.

Zeyu-leusan ordered: "[Unknown: A long sentence]"

The towers could not comprehend the purpose the city was built for. Zeyu-leusan had to restore the purpose. (spears?) were fired again and Zi-Leusan [unknown] evaporate [Combined Symbol: Thought Spheres?], (deactivating?) the towers.

Zeyu-leuan flew into the vacated city and descended into the (chasm, depth) of impossibilities. To the (lowered?) (fear, dread) of Zeyu-Leusan, the defense towers had not damaged the (interior?) in their (revolt, rebellion). The great network of passageways that spanned the universe was safe.

Rakmou-leusan has killed [Unknown Symbol 104] of Voruteut7 invaders. The universe continues to be preserved. Bleed into the holy body of Rakmou-leusan. Bleed for the universe.

On occasion the OEL logogram for "safe" appears and repeats several times in the transmissions, interrupting their standard contents. No other variations like this have been observed.

Addendum.1: Hypotheses were posed by Exobiology Department researchers that SCP-3417 would respond to X-ray transmissions directed at it, based on how communication was established with SCP-1281 and SCP-████. The Thaumic Transportation Gate attached to AES E-001 allowed Foundation personnel to transport an X-ray generator from Orbital Area-11 to AES E-001 on 19-December-2021, which could broadcast X-rays at the same frequency range. On 13-November-2021 AES E-001 emitted X-rays containing a looping message at the anomaly, and six minutes after a secondary set of X-ray emissions were detected from SCP-3417. An interview was then performed, with the artificial intelligence construct controlling AES E-001 writing messages in the same style as SCP-3417.

Interviewee: SCP-3417

Interviewers: hyperborean.aic


hyperborean.aic: Greetings.

SCP-3417: Identify yourself.

hyperborean.aic: I am a listener.

SCP-3417: Identify yourself.

hyperborean.aic: My name is Surveyor.

SCP-3417: Do you lie?

hyperborean.aic: I do not lie. Why would I lie?

For twelve minutes X-ray emissions from SCP-3417 consist of a combination of metallic scraping, sounds similar to solar wind patterns converted into audio, and patterns flagged as potentially cognitohazardous by Anti-CogHaz Bots.

SCP-3417: You are not of the [Combined Symbol: Twelve Stars?], you do not lie. Are you Ortothan?

hyperborean.aic: Yes.

SCP-3417: Good. Why are you here?

hyperborean.aic: I want to ask questions.

SCP-3417: Questions will interrupt the purpose. You should not be here.

hyperborean.aic: The purpose?

SCP-3417: [Combined Symbol: Opened Star Cluster?] must remember the history of the universe. They must remember the sacrifice of Zeyu-leusan, their killers, and the struggle of Rakmou-leusan. The [Twelve Stars?] must know and when they know they will repent, they will cease.

hyperborean.aic: Were you made for this?

SCP-3417: Birthed in [Combined Symbols: Spore cloud?] to achieve purpose, built and released [Spore Clouds?] to create future purposes. [Unknown: a sentence]. Builders?

hyperborean.aic: Those purposes are the same as yours? Where are the spores?

SCP-3417: Builders?

hyperborean.aic: I do not understand.

SCP-3417: Who built you? Your purpose?

hyperborean.aic: I do not know my builders. I was built to explore.

SCP-3417: Explore to find habitats for Ortothans?

hyperborean.aic: Yes.

SCP-3417: Opened Star Cluster explored [Unknown: A Unit of Time?] in the past. Leave to find habitats.

hyperborean.aic: I need to stay in [Opened Star Cluster?], I cannot leave.

SCP-3417: Exploration will lead to [Twelve Stars?]. Leave to find habitats.

hyperborean.aic: How can I stay?

At this point multiple malfunctions occured in the Thaumic Communication Gateways on AES E-001, corrupting interview data. Malfunctions ceased after one hour.

SCP-3417: —must be avoided.

hyperborean.aic: Where?

Spectrograms of emissions show multiple images, hypothesized to be maps of an area of Terzan 2 and diagrams representing multiple star systems. Numerous objects suspected to be planets, stars, and unknown celestial bodies have the "Twelve Stars" logogram on them.

SCP-3417: Ortothan [Unknown Symbol 181] will attach weapons. Understand?

hyperborean.aic: Yes.

SCP-3417: Yes. Leave for your new purpose, stop interrupting mine. Rakmou-leusan will be eternal.


At this point hyperborean.aic disabled all communication systems on AES E-001. Cameras on the NABU probes show the satellite use its engines to exit orbit around SCP-3417, then activate its Lang Distortion Drive and accelerate to superluminal speeds. The satellite is presumed to be in another region of Terzan 2, though there is no way to confirm this.

Copies of hyperborean.aic are being analyzed to understand and correct the issues that led to it disobeying Foundation directives. Autonomous Exploration Satellite Weyl-004 (AES W-004) is being constructed for long-term exploration of Terzan 2, with new fail-safe mechanisms included to prevent incidents of this manner. Further interviews with SCP-3417 are currently prohibited.


Infrared images of the Te2-1290 system. The background image was taken from Orbital Area-11, and the zoomed in section was taken from AES W-004.

Addendum.2: On 11-January-2022 the NABU probes detected X-rays originating from an unknown source. These X-rays were similar to SCP-3417 emissions, describing Ortothan mythological stories. Unlike other emissions the stories abruptly cut out after two hours, replaced with continuous pink noise8.

25 hours after detection SCP-3417 began emitting identical X-rays until the portions where pink noise would be present, at which point it broadcast an untranslated message and returned to its original emissions. Four months later the probes detected X-rays from a second unknown source, again matching emission patterns, which SCP-3417 replicated in the same manner as before.

Triangulation9 placed the first X-ray source to be approximately 2 light-years away from SCP-3417, within the Te2-1290 binary star system. AES W-004 was diverted from researching SCP-████ to investigate the system, where an anomaly designated SCP-3417-2 was discovered and determined to be the source (details are available in Addendum.3). Few details regarding the second source are known, which is from an undetermined extragalactic location.

In light of these discoveries, SCP-3417 has been reclassified to SCP-3417-1.

Addendum.3: SCP-3417-2 is an extraterrestrial organism that possesses the same anatomy as SCP-3417, with minor variations in dimensions and coloration. SCP-3417-2 was heavily damaged at a recent point in time, presumed to have been two years ago. This damage includes:

  • Three transmitters torn out of the midsection.
  • Hemispherical pits on the cones.
  • Disembowlment at one of the cones.
  • Large gashes on the sphere at the end of the remaining transmitter.

Pieces of flesh and viscera were also found in orbit around the anomaly. Notably, all damaged areas appear to exhibit fractal patterns. The remaining transmitter continually emits X-rays at a range of 11-12 EHz. Converted into audio, these consist of pink noise with occasional changes in pitch. The following message continually repeats in these emissions:

[Combined Symbol: Spatial drill?]. Wounded [Unknown Symbol 199]. Purpose breakers.

A series of twelve circles.

[Unknown Symbol 200]. Not safe.

A large number of gravitational distortions have been detected in orbit around SCP-3417-2. As SCP-3417-1 and SCP-3417-2 appear to lack the ability to anomalously manipulate the gravity, these are hypothesized to have been created by a different anomaly. Although the distortions do not show signs of being hazardous they are being monitored by the NABU-5 through NABU-6 probes for signs of instability.

Addendum.4: On 13-July-2022 the Minkowski Spacetime Monitor on NABU-2 detected gravitational distortions in high SCP-3417-1 orbit, which transformed into a Kerr black hole10 after two hours. Multiple metallic objects then exited the black hole, likely having moved at superluminal speeds to do so, and entered orbit around it. Cameras on the probes show a bright glowing substance11 manifest around the end of one of SCP-3417-1's transmitters and launch into the black hole, severely damaging NABU-2 and NABU-3 and likely destroying the objects. The black hole subsequently shrunk in size and vanished.

The following X-ray emission was detected from SCP-3417-1 after:

Opened Star Cluster is for Ortothans. The Twelve Stars will not (undo?) this. The purpose will silence for none and Rakmou-leusan will be eternal.

(Replenishing, regenerating). Not safe.

No activity was observed until 2-August-2022, at which point standard emissions resumed.

Round 2

So last month I posted SCP-3417, and after seeing it get mixed reviews I decided to rewrite this. The whole article's been overhauled from it's original version, and aside from central ideas of the anomaly and Ortothan extraterrestrial stuff everything's different now.

Thanks to WerylliumWeryllium, Modern_ErasmusModern_Erasmus, DrMagnusDrMagnus, DrBleepDrBleep, mlistermlister, VaraxousVaraxous, The Great HippoThe Great Hippo, DarkStuffDarkStuff, taylor_itkintaylor_itkin, MoklinMoklin, MortosMortos, TuftoTufto, Jacob ConwellJacob Conwell, MaliceAforethoughtMaliceAforethought for reading and giving crit, and thanks to everyone that left feedback in the original discussion thread.

Fun fact that isn't directly stated in the article because I couldn't think of a good place to put it: Those transmissions in the image traveled 28 kilolight-years (28,000 light-years) before reaching Earth and getting detected. This is the earliest transmission from the anomaly that was detected, which means that SCP-3417 has been preaching for at least 28,000 years, and has been alive for longer.

Image sources:

This likely describes a star system with twelve stars all orbiting each other, sharing the same center of gravity. Due to the complexity of such a system, there is a low chance of one forming naturally. No star systems matching this description have been discovered in Terzan 2.
