SCP-2108

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.

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 Ө-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 4 m straight down. This placed it below the level of the warehouse's skylight, simultaneously making it visible for the first time³ 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.)

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.
