Living organisms are not to be exposed to SCP-2108 or SCP-2108- 
A. Video should be converted to grayscale or false color before 
viewing. When direct observation is necessary, personnel should 
wear full-body opaque clothing with goggles tinted to block 
SCP-2108-A's characteristic spectral peaks. SCP-2108-A skin 
exposure of 80 J/kg in any ten-week period is disqualifying for 
further SCP-2108 interaction. 


Instances of SCP-2108-B are to be contained in species-appropriate 
enclosures at least 10 km from Site-2108, except when authorized 
for testing. Deliberately creating instances of SCP-2108-B requires 
prior authorization from the SCP-2108 project lead, and in all cases 
must use the fewest and least massive subjects possible. 


Description: SCP-2108 is a luminous object resembling a miniature 


star with a chromosphere 1-4 m in diameter, ranging in color from 
yellow-orange to green. It is selectively intangible and possibly non- 
material, but appears similar in structure and composition to a main- 
sequence star of roughly one solar mass; its surface bears visible 
granules and sunspots, it appears to undergo periodic flares, and it 
has a gaseous corona 0.5-6 m deep. It emits 1.8-15.3 kW of light, a 
biologically insignificant level of exotic [DATA REDACTED] 
radiation, and very little radiant heat. It cannot be moved or affected 
by deliberate physical manipulation, except by some instances of 
SCP-2108-B (see below). 


SCP-2108's specific properties, such as size, location, mass, 
absolute luminosity, spectrum, etc., vary in poorly-understood ways. 
All of its properties are correlated nonlinearly with one another as 
well as with at least twelve other factors. These additional correlates 
have not been fully enumerated, but are believed to include the 
current solar-wind flux; strong local magnetic fields; the movement 
of all Corvus individuals within 13 m of the object; the extent of the 
next predicted solar and lunar eclipses; the time elapsed since a 
runaway nuclear fission reaction took place in the Northern 
Hemisphere; and the number and combined mass of extant 
SCP-2108-B instances. 


Light and radiation emitted from SCP-2108 is designated SCP-2108- 
A. Its spectrum varies somewhat, as do all of SCP-2108's 
properties, but always retains characteristic peaks at 663, 615, 448, 
and 297 nm (i.e. in the red, orange, indigo, and near ultraviolet). In 
addition, the object's exotic-radiation output is its only predictable 
property: it is always a known function of SCP-2108-A's 
electromagnetic spectrum. ! 


Intense or prolonged exposure to unmodified SCP-2108-A causes a 
poorly-characterized transformative syndrome in living organisms, 
which are then designated SCP-2108-B. The speed and discomfort 
of SCP-2108-B conversion are directly proportional to the speed and 
intensity with which the transformative SCP-2108-A dose was 
delivered.2 Without continued SCP-2108-A exposure, instances of 
SCP-2108-B invariably revert to their original state within eight 
weeks. (See Addendum 2108-E-46693.) 


The changes present in SCP-2108-B are believed to result, at least 


similarities withSCP-2101suggest that these anomalies may 
descend from the same anomalous sculpting tradition.

in part, from protein-folding interference by novel substances 
produced upon skin absorption of SCP-2108-A. The precise effects 
vary between taxa, but generally include an increase in external 
pigmentation; production of novel pigments with absorption spectra 
related to SCP-2108-A; and, in autotrophic organisms, a novel set of 
photosynthetic organelles and pathways better optimized for use of 
SCP-2108-A. Structural and organ-level effects are usually subtle, 
with more pronounced changes affecting the organism's metabolism 
and biochemistry. Extended exposure may produce more dramatic 
structural effects; testing proposals are currently under review. See 
Addendum 2108-1 for a partial list of SCP-2108-B alterations. 


Addendum 2108-1 
Selected Excerpts from Test Log 2108-B 


Test 1 

Subject: Three mature American goldenrod (Euthamia 
graminifolia) plants, in fruit 

SCP-2108-A exposure: Discovered with SCP-2108 in 
Site-2108 Core; total dosage unknown. 

Conversion period: Unknown 

Results: Initial discovery of SCP-2108-B. Plants' leaves 
distinctly longer and thinner than typical for E. 
graminifolia. Leaf and stem surface pigmentation 
purplish-blue with slight cyan iridescence, apparently a 
protective "sunscreen" layer; underlying tissues deep 
blue-green due to development of SCP-2108-B-typical 
photosynthetic systems. Fruits rich in several 
uncharacterized alkaloids. After removal from SCP-2108- 
A, plants recovered entirely within 8 weeks. 


Test 3 

Subject: Colony of carpenter ants (Camponotus 
pensylvanicus), >200 individuals 

Exposure: Discovered with SCP-2108 in Site-2108 
Core; total dosage unknown 

Conversion period: Unknown 

Results: Dosage presumably proportional to time spent 
outside the nest, as effects were most pronounced in the 


workers tasked with foraging. Thorax, legs, and 
mandibles coated in several thin layers of translucent, 
deep-orange wax, and comblike chitinous appendages 
developed on the dorsal antennae. Signaling 
pheromones almost completely replaced with a novel set 
of chemicals; resultant confusion between foraging 
workers and larva-care workers likely caused the 
colony's rapid decline. Queen completely unaffected, but 
killed by alkaloid poisoning after being fed seeds of 
affected goldenrod; colony then collapsed completely. 


Test 9 

Subject: 2 albino Norway rats (Rattus norvegicus), 
female, 18 months old, 330-375 g 

Exposure: 160 J/kg / full body skin, fur, and eye / 240 
minutes 

Conversion period: 66 hours 

Results: Exposed skin developed light gray 
pigmentation; fur developed dark blue-gray pigmentation 
with dark blue mottled markings whose exact patterns 
differed by individual. Behavior during conversion period 
did not suggest any particular discomfort. Animals 
recovered within 3 weeks. 


Test 10 

Subject: 2 albino Norway rats (Rattus norvegicus), 
female, 18 months old, 335-360 g 

Exposure: 160 J/kg / full body skin, fur, and eye / 10 
minutes 

Conversion period: 75 minutes 

Results: Comparable to Test 9, but with additional slight 
elongation of tail vertebrae and hind legs. Subjects 
chewed and clawed at legs and tails until restrained, with 
vocalizations suggesting discomfort and/or pain. Joint 
swelling, colorful urine, and other symptoms of 
endogenous pigment poisoning abated within 24 hours; 
animals recovered within 3 weeks. 


Test 11 
Subject: 2 albino Norway rats (Rattus norvegicus), 


female, 18 months old, 320-370 g 

Exposure: 160 J/kg / full body skin, fur, and eye / 240 
minutes. Light used was an exact match to SCP-2108- 
A's current spectrum, generated by filtered floodlamps. 
Conversion period: n/a 

Results: No effect. 


Test 12 

Subject: Same individuals as Test 11 

Exposure: 90 J/kg / full body skin, fur, and eye / 240 
minutes. Light used was live, full-color surveillance video 
of SCP-2108. 

Conversion period: 80 hours 

Results: Effectively identical to Test 9. 


Test 15 

Subject: Human, male, 27 years, 79 kg (D-2108-14) 
Exposure: 160 J/kg / 20 cm2 skin, torso / 240 minutes 
Conversion period: 12.5 hours 

Results: All skin developed purplish-brown pigmentation 
with short blue-green ventral stripes. Subject reported 
altered color vision, as well as difficulty speaking and 
eating due to excessive salivation. Blood rich in a novel 
substance with significant stimulant effects in mouse 
models but none in the subject himself. Recovered within 
3 weeks. 


Test 16 

Subject: Human, male, 27 years, 79 kg (D-2108-14) 
Exposure: 160 J/kg / 20 cm2 skin, torso / 240 minutes 
Note: D-2108-14 was re-exposed after recovering fully 
from Test 15. 

Conversion period: 3 hours 

Results: Comparable to Test 15, but with additional 
complications of the shorter conversion period: joint 
swelling, muscle spasms, mild hemophilia, greater loss 
of vision, and colorful body fluids. Symptoms abated 
within 36 hours; subject recovered within 7 weeks. 
Repeated re-exposure tests pending approval. 


Test 


Subject: Human, female, 38 years, 64 kg ( . ) 
Exposure: Accidental, 125 J/kg / 5 cm2 skin and eye /5 
seconds (post hoc estimation) 

Conversion period: 5 minutes (post hoc estimation) 
Results: Skin developed purplish-brown pigmentation 
with blue-green ventral mottling; color vision altered, 
apparently tetrachromatic; skin hairs replaced by chaffy 
oval structures with rudimentary photosynthetic capacity. 
Onset of SCP-2108-B characteristics was swift enough 
to cause immediate, severe endogenous poisoning: 
symptoms included muscle spasms, systemic neuralgia, 
temporary blindness, and acute renal failure. Poisoning 
symptoms abated in 3 weeks with inpatient care; severe 
sunburn on exposed side of face healed normally; 
subject recovered fully within 8 weeks. 


Addendum 2108-2 
Incident Report E-31181-A 


On 12 February 2014, Agent Erin Moynahan, 
Researcher Thom Saint-Jacques, and Researcher 
Chelsea Elliott, representatives from MTF Theta-—4 
("Gardeners"), arrived at the future Site-2108 to 
assist in early field study of the anomalies that would 
collectively be designated SCP-2108. At the time, 
SCP-2108-A and -B were collectively designated 
E-31181; SCP-2108 itself had not yet been discovered. 


The MTF ©-4 personnel were directed to the SCP-2108- 
B entities, which consisted of scattered vegetation 
growing in the cracks of the concrete warehouse floor, 
and began initial examination after establishing basic 
field precautions. However, when Dr. Elliott attempted to 
examine a leaf sample through a small magnifying lens, 
she received a burst of concentrated SCP-2108-A. The 
exposure converted her into an instance of SCP-2108-B 
within five minutes; the resulting endogenous poisoning 
required hospitalization. 


Simultaneously, the sudden emergence of a large 
SCP-2108-B instance caused significant changes in 
SCP-2108's properties, most notably causing it to triple 
in diameter and luminosity while instantly relocating 4m 
straight down. This placed it below the level of the 
warehouse's skylight, simultaneously making it visible for 
the first time and irradiating all personnel present. Agent 
Moynahan, Dr. Saint-Jacques, and on-Site Agent 
Shoshanna Segel became instances of SCP-2108-B 
over the following four hours; the additional converted 
biomass caused further erratic movement of SCP-2108. 
The resulting positive feedback loop would likely have 
converted much of the surrounding city if not for routine 
testing at Provisional Site- , in which SCP- - 
underwent its weekly partial core meltdown, resetting 
one of SCP-2108's major property correlates and 
instantly relocating it to a position inside Site-2108 Core. 


Strategic application of disinformation and amnestics 
ensured no lasting public exposure. All personnel 
converted to SCP-2108-B recovered within eight weeks. 
(See Addendum 2108-E-46693 for records of extended 
observation.) 


Addendum 2108-E-46693 
[Enter 5/2108/E-46693 authorization code to continue.] 


Like the other personnel involved in Incident E-31181-A, 
Dr. Elliott appeared to recover completely from the 
effects of SCP-2108-B conversion; she completed 
quarantine and was cleared for duty upon recovering 
fully from her injuries. However, recent events indicate 
that this assessment was premature. 


Routine surveillance carried out on Dr. Elliott after the 
incident revealed irregularities in her eating habits; 
although initially consistent with her established habits, 
these disturbances grew steadily more pronounced after 
the incident. When she fasted for sixteen straight days in 


late April, with neither any apparent preparation nor any 
ill effects, her case was flagged for closer and more 
prolonged examination. 


Over the following months, surveillance established that 
Dr. Elliott's food consumption patterns are closely 
correlated with her exposure to daylight or comparable 
full-spectrum lamps. She also displays marked 
symptoms of seasonal-affective disorder, despite no 
history of the condition, for which she self-medicated with 
full-spectrum lamps. Additionally, on seven separate 
occasions in May and June, she was briefly hospitalized 
for acute accidental poisoning; all seven incidents 
appear to have been caused by plant toxins whose 
sources were either entirely absent or available only in 
quantities far smaller than apparently ingested.4 The 
origin of the toxins is unknown. 


Taken together, these phenomena suggest that Dr. 
Elliott has acquired anomalous properties beyond those 
characteristic of SCP-2108-B, which have persisted and 
strengthened since the incident. She has been 
provisionally classified as E-46693; proceedings to 
classify her as an SCP object were filed in June 2014, 
but have since been postponed indefinitely pending O5 
review.

SCP-2108-A dose and to the inverse cube of the time over which it 
was applied. 

3. Before Incident E-31181-A, SCP-2108-A shone through the 
skylight of Site-2108 Core, but SCP-2108 was not visible from 
outside the building. This phenomenon has not recurred and 
remains unexplained. 

4. The toxins included black walnut hull extract; caffeine, in 
concentrations greater than could have been ingested normally; and 


aconite sap, in sublethal doses.

SCP-2109: A Tragic Accident 


Item #: SCP-2109 
Object Class: Euclid 


Special Containment Procedures: Information regarding 
SCP-2109 is largely self-containing and requires no information 
suppression on behalf of the Foundation. 


The detection of potential SCP-2109 cases is to be handled by 
automated systems designed for this purpose. Such systems are 
designed to detect discrepancies in legal, medical, press and 
bureaucratic documents associated with SCP-2109. Personnel 
involved in investigation of SCP-2109 are to defer to the results 
produced by such systems rather than their own judgement when 
determining the probable existence of an SCP-2109 case. 


All recordings or footage involved in SCP-2109 cases are to be 
analysed via SILVER CRESCENT! protocols. If an SCP-2109 case 
is confirmed, investigative personnel are to attempt to retrieve any 
documents or data storage devices belonging to the deceased 
which relate to mathematics or which were acquired or composed 
shortly before their death. 


Documents relating to SCP-2109 are not to be stored centrally, 
either in physical or digital form. Any location where SCP-2109 
documents are stored must be surveilled using SILVER CRESCENT 
protocols. 


Description: It should be noted that most knowledge of SCP-2109 
is not drawn from direct observation, and its existence can to a large 
extent only be inferred. 


SCP-2109 is a phenomenon affecting the deaths of certain people, 
their corpses, and all legal proceedings relating to those deaths. 
SCP-2109 is suspected to be infohazardous in nature. All cases 


affected by SCP-2109 have been deaths by natural causes, and 
have a tendency to involve students and academics, particularly 
involved in certain fields of mathematics, though this is not always 
the case.
