Nigeria, Cross River National Park: 'Abyssal Colossus and Resonating Infrasound' Unidentified Massive Animal Case
Summary
On August 13, 2018, researchers conducting an ecological survey in the remote areas of Nigeria's Cross River National Park witnessed unusual infrasound and a massive shadow. This sound, unlike any known animal, induced an uncomfortable vibration in human hearing. The observed shadow was large enough to dwarf the trees, appearing to dissolve into the surrounding darkness as if absorbing light. Authorities suspect this phenomenon is caused by an unidentified creature and have initiated a large-scale investigation. However, its true nature remains elusive.
Details
At 11:37 PM on August 13, 2018, in an uncharted sector of Cross River National Park, a botanist recording vegetation first perceived a peculiar vibration and infrasound, as if rising from the ground. Immediately thereafter, the canopy approximately 50 meters ahead violently swayed, and a massive shadow briefly appeared, obscuring the moonlight. The shadow lacked a clear outline and vanished as if dissolving into the surrounding darkness. This report closely resembles local tribal legends and isolated accounts from logging workers over several decades concerning a 'Lord of the Forest.' They recount that during specific seasons and lunar phases, a 'roar from the depths of the earth' resonates from deep within the forest.
Authorities dispatched an investigation team to the site, deploying state-of-the-art acoustic measurement devices, thermal cameras, and high-resolution drones. The infrasound registered consistently within a specific frequency band (approximately 15Hz to 25Hz), indicating a likely biological origin, but the source could not be pinpointed. Thermal cameras intermittently captured a massive heat source moving rapidly through the trees for brief periods; however, its shape constantly shifted, yielding insufficient data to identify its true form.
During the investigation, on May 7, 2019, a drone flying deep within the forest suddenly lost communication and crashed. The recovered aircraft sustained minor physical damage, but data within its internal recording device was partially corrupted. Furthermore, several investigators reported chronic tinnitus and headaches, suspected to be related to infrasound exposure. Their testimonies exhibited striking consistency regarding the shape of the observed shadow and the circumstances of the sound's generation, suggesting the possibility that it was not merely a collective hallucination.
Authorities have so far been unable to attribute this phenomenon to any known biological species. Given the vastness of the forest and its numerous unexplored areas, the possibility of an unknown large organism residing there cannot be ruled out. However, its ecology and behavioral principles remain unknown. In particular, the compounded effect on sound and vision, as well as the potential for electromagnetic interference, suggest phenomena beyond mere biological classification.
Currently, authorities are establishing an extensive observation network to test the hypothesis of periodic activity. Information regarding the creature's impact on the surrounding ecosystem, especially its role as a predator and interactions with other organisms, is also lacking. Local tribal legends could be interpreted as suggesting its role in maintaining the forest's balance, but scientific evidence is currently absent.
This case presents a complex interplay of biological inquiry and further unexplained phenomena. Ongoing investigation is imperative to elucidate its true nature and define its place within the local ecosystem. The Bureau maintains constant vigilance for further information gathering and analysis.

Witness Testimony
Witness A (Biologist)Suddenly, I felt the ground pulsate. It was like a low, deep growl. Then, the trees in front of me swayed violently, and something massive emerged from the darkness. It was a black mass that seemed to absorb light, and it vanished in an instant. I am certain it was not an animal.
Local Hunter BThe 'Abyssal One' dwells deep in the forest. Before dawn, when the moon is completely hidden, a voice echoes from beneath the earth. It shakes the forest, and the prey falls silent. We do not approach it. It is the voice of the forest itself.
Kyu's Analysis
This case is more than just a report of an unidentified creature. The infrasound and electromagnetic interference suggest its existence may transcend our current understanding of physical laws. Continuous monitoring and data collection are essential.
