Disturbing reports are reaching us from a lighthouse located on Saint-Mathieu Island, off the Breton coast. The keeper has not been in contact with maritime authorities for 43 days. The last three rescue teams sent (twelve people in total) never returned to shore.

Preliminary analysis of radio transmissions picked up within an 8 km radius of the lighthouse:

  • Fragmented transmissions interspersed with long periods of silence
  • Significant sound distortions (frequency modulated between 15 Hz and 22 kHz)
  • Presence of sounds impossible to produce with normal vocal cords
  • Recurring messages: "I see what should not be seen," "My eyes are lying to me," "The light devours"

Several local residents report anomalies in the lighthouse’s beam:

  • Abnormal refraction (measured index of 2.87 vs. 1.0 for standard air)
  • Incomplete chromatic spectrum with a total absence of red (570-750 nm)
  • Irregular rotation with exact 5-second pauses

The last team to establish visual contact from a boat 500 meters off the coast reported increasing perceptual distortion as they approached the island. Reported symptoms: dizziness, sensory confusion (tasting colors, seeing sounds), ocular bleeding.

Exploration authorization granted. Allocation of 30 explorers.

Losses: 3

Notes:

Arrival on the island at 05:37, before sunrise to avoid direct exposure to the lighthouse beam. Initial readings are alarming:

  • Neuronal repulsion rate (theta waves): 38.5 ψ/s (normal: 4-7 ψ/s)
  • Induced vestibular degradation: 0.87 on the Brodmann scale (normal: 0.05)
  • Retinal exposure to ambient light: 175% of the maximum tolerated value, despite relative darkness

Explorers report an immediate sensation of "sensory desynchronization" upon landing on the shore. Explorer #8 notes that "the roar of the waves seems to come from inside my skull rather than the sea." Explorer #15 reports that "the air has a metallic taste that leaves visible blue traces on my tongue."

At 100 meters from the lighthouse, the team discovers the body of the first rescuer. Preliminary autopsy:

  • Eye sockets manually emptied
  • Eardrums perforated, likely by his own fingers
  • Tongue severed and found in his jacket pocket
  • Nostrils cauterized with a heated object

His notebook contains a single sentence repeated across 17 pages: "I can no longer bear the lies of my senses."

Progression toward the lighthouse. At 50 meters, three explorers (#4, #11, and #23) begin showing alarming symptoms:

  • Pupils fully dilated (9mm)
  • Bleeding from auditory orifices
  • Increasing confusion between stimuli ("I can smell the blue," "The ground is screaming")

They start running toward the shore, screaming. We lose sight of them but hear three distinct splashes. Their bodies are found floating face-down in the water, showing no signs of struggle. Residual brainwave analysis: 286 Hz on a band normally capped at 30 Hz.

Losses: 6

Notes:

Entry into the lighthouse at 04:12. The measured light intensity inside defies logic: 0.003 lux (darker than a moonless night) yet perfectly visible. Explorers report seeing through walls, glimpsing their colleagues’ internal organs, and perceiving nonexistent colors.

The ground floor is covered with inscriptions carved into the walls. Graphological analysis: same author, likely the lighthouse keeper. The texts describe a horror that feeds on sensory distortions, "dwelling in the gap between perception and reality."

Discovery of the second rescue team’s bodies. They appear to have killed each other while attempting to tear out their sensory organs. One victim still holds fragments of a colleague’s ear between their teeth.

At 06:30, exploration of the first floor. Readings:

  • Air electrical conductivity: 78 S/m (comparable to seawater)
  • Perceived vs. measured temperature: 22°C discrepancy
  • Recorded sound waves exhibiting an inverted structure (attack at the end, decay at the start)

Explorer #17 begins behaving strangely, claiming his skin "lies" and that he must remove it to see the truth. When we attempt to restrain him, his entire body hardens like stone, reaching a hardness of 8.5 on the Mohs scale. He then emits a 158 dB sound, causing cerebral hemorrhages in two explorers (#2 and #19). Three others (#5, #24, and #28) suffer ruptured ocular blood vessels and die within minutes from massive brain damage.

Losses: 8

Notes:

Progression to the second floor. The spiral staircase seems to lengthen as we climb. Structural analysis: 68 steps counted ascending, 34 descending.

Disturbing readings:

  • Neuronal depolarization in explorers: 300% above critical threshold
  • Measurable sensory confusion: 83% of stimuli reach incorrect brain regions
  • Microfractures in explorers’ cranial bone structure (0.5mm wide)

At 09:15, Explorer #6 begins seeing colors emanating from sounds. He describes the sound of our footsteps as "deep purple with silver bursts." Ten minutes later, he claims the silence between our words "smells like rotting flesh" and that this odor "burns him from the inside." He dies suddenly, his body wracked by convulsions so violent his spine snaps in three places.

Arrival at the lantern level at 10:42. We discover the source of the anomalies: where the traditional Fresnel lens should be stands an indescribable horror.

It appears composed of perception fragments: visual echoes, sonic residues, tactile impressions floating in a confined space. At its center, a swirling mass of sensory stimuli torn from its victims. Eyes, ear fragments, and strips of skin float in this maelstrom, connected by luminous filaments to the central source.

Symptoms near the horror:

  • At 5 meters: confusion between sight and hearing
  • At 3 meters: inverted tactile perception (hot becomes cold, pain becomes pleasure)
  • At 1 meter: extreme and painful synesthesia

Explorer #10 approaches too closely and begins to sensorially disintegrate: his eyes project images into the air, his skin emits sounds, his ears ooze odors. He begs to be put out of his misery before being fully absorbed by the horror.

Attempted analysis of the horror:

  • Composition: unanalyzable by conventional instruments
  • Structure: pentadimensional (hints of a fifth sensory dimension)
  • Estimated age based on light degradation: predates the lighthouse (>150 years)

Six explorers (#1, #7, #13, #18, #22, #29) succumb during additional measurements, their bodies transformed into aberrant sensory conduits. Explorer #22 becomes transparent, revealing internal organs emitting distinct sounds. Explorer #29’s skin turns into a reflective surface projecting sensory memories of past victims.

After studying the wall inscriptions and analyzing the horror’s behavior, we understand it feeds on sensory confusion. The lighthouse keeper had apparently found a temporary way to appease it.

Chosen: 5

Progression: Preparing the Sacrifice

Research in the lighthouse archives uncovers critical information. The horror is mentioned in 18th-century texts as "The Thief of the Five Gates." Local fishermen once performed an annual appeasement ritual involving five people.

According to the texts, the horror can be temporarily banished through a symbolic sacrifice of the five senses. Each sacrifice must be voluntary and involve the permanent loss of a sense.

Ritual preparation begins at 03:00. Five explorers volunteer (#3, #9, #12, #20, #27).

Pre-ritual readings:

  • Ambient sensory intensity: 524% above perceptual saturation threshold
  • Cognitive distortion rate: 88%
  • Perception-reality separation index: 0.15 (normal: 0.97)

The Sacrifice:

At exactly 05:55, the five chosen position themselves in a pentagon around the horror, each representing a sense.

Explorer #3 (sight) pours acid into his eyes, declaring: "I offer the lies of my eyes to the true darkness."

Explorer #9 (hearing) pierces his eardrums with a heated blade, declaring: "I offer the illusion of sounds to eternal silence."

Explorer #12 (touch) plunges his hands into liquid nitrogen and shatters them, declaring: "I offer false caresses to true pain."

Explorer #20 (smell) cauterizes his nasal cavities, declaring: "I offer deceptive scents to odorless void."

Explorer #27 (taste) severs his tongue, declaring through gurgles: "I offer meaningless flavors to true hunger."

As the final word is spoken, the horror begins to contract. The luminous filaments connecting the sensory fragments break one by one. The maelstrom collapses into an increasingly smaller point, emitting pulses at exactly 5 Hz.

Readings during contraction:

  • Light intensity drops from 230,000 lux to 0.001 lux in 5 seconds
  • Soundwave compression creates an acoustic vacuum of -12 dB
  • Temperature fluctuates between 52°C and -18°C at 0.2-second intervals

At exactly 06:00, the horror implodes in a silent flash and vanishes. In its place remains a small object: a 5 cm diameter dodecahedron, each face engraved with symbols representing one of the five senses.

Preliminary analysis of artifact RT205-PL:

  • Composition: unknown, semi-organic material
  • Properties: absorbs 98.3% of incident light
  • Effect on perception: staring at it for over 5 seconds induces "perfect sensory clarity" for exactly 5 minutes
  • Potential danger: repeated use causes severe dependency and degradation of natural sensory abilities

The lighthouse is secured, and the artifact is placed in a specialized container with full sensory isolation. The five surviving chosen are placed under medical observation, showing complete immunity to sensory distortions but unable to reconnect their lost senses.

Summary:

Mission accomplished. Artifact secured, horror banished, losses acceptable.

Financial Costs:

  • Equipment: €1,850,000
  • Salaries: €65,000
  • Death insurance: €340,000
  • Sensory containment unit construction: €420,000
