Case No. #1037
Ancient Echoes in the Desert
Summary
On the night of October 15, 2017, remote surveillance cameras recorded irregular humming sounds and faint luminescence emanating from unidentified ancient ruins near Tassili n'Ajjer National Park in southern Algeria. This phenomenon is limited to desert nights and becomes prominent only in uninhabited environments. It is linked to local legends of "sand songs" passed down by nomads for centuries. The authorities attempted to identify the source of the sound and light, but its mechanism remains unexplained to this day.
Details
At 2:14 AM on October 15, 2017, deep within Algeria's vast Sahara Desert, an unnamed complex of ancient ruins registered an anomaly via the remote surveillance system installed by the authorities. Low, irregular humming sounds and faint, bluish light, synchronized with the sounds, intermittently originated from the center of the ruins and were recorded for approximately 37 minutes. This event was logged as a new type of anomaly, previously unobserved.
The ruins consist of stone structures estimated to date back to around 3000 BCE, and have long been revered by the local Tuareg tribes as 'stones where voices echo.' Reports from a French archaeological team that investigated the area in the 1970s also contain multiple accounts of experiencing unexplained 'low-frequency vibrations' and 'resonant sounds' during night surveys. These align remarkably with local legends of 'the desert spirits' song.'
The authorities cross-referenced past records and confirmed multiple anonymous reports from civilians between 2001 and 2016, stating they had 'heard strange sounds deep in the desert' or 'seen lights from the ruins in the night sky.' While these reports were sporadic and lacked concrete evidence, many overlapped geographically and temporally with the current event, deepening doubts about the phenomenon's isolated nature. The anomalous occurrences tend to happen frequently on moonless, dark nights, especially under dry atmospheric conditions.
Authorities immediately dispatched an investigation team to the site, installing multiple high-sensitivity microphones, spectral analysis devices, thermal sensors, and electromagnetic wave detectors. However, during the team's stay at the ruins, recorded sounds were extremely faint, and no luminescence occurred. Within hours of the team's withdrawal, the surveillance system again recorded the same humming sounds and light phenomena as before.
Further inexplicably, state-of-the-art wireless communication equipment installed at the time of the phenomena repeatedly suffered unexplained malfunctions. While intense electromagnetic noise was observed in specific frequency bands, its source could not be identified. Additionally, the luminescence captured by high-resolution cameras appeared as a misty, flickering glow without a discernible light source or clear shape. Data analysis revealed that the recorded humming sounds contained non-periodic variation patterns, distinct from known biological vocalizations.
Interviews with local nomads revealed that their 'sand songs' sometimes sounded like human speech, other times like distant animal cries, indicating varied interpretations. However, no one had approached the ruins during periods of active phenomena, and detailed eyewitness accounts were unobtainable. They consistently stated that 'the ruins keep people away at certain times.' This collective avoidance behavior itself is highly likely an aspect of the phenomenon.
To this day, neither the mechanism nor the source of the phenomena at this ruin complex has been resolved. Remote monitoring continues, but predicting the phenomena remains difficult, and direct contact by investigation teams still poses significant risks. The authorities regard this incident as an extremely peculiar spatial anomaly in the Sahara Desert, or a sign of territorial maintenance by an unknown entity.
Ongoing observational data strongly suggests that these 'voices' are not attributable to mere natural phenomena or geological activity. The authorities maintain their policy of prioritizing long-term data collection and analysis to identify recurrence conditions and patterns of the phenomena.

Witness Testimony
Witness A (Nomad)That is the voice of the desert spirits. If a human approaches, they will be swallowed by the sand. It is wise not to go near when the song echoes.
Investigator C (Anonymous)It was a strange silence. Nothing happened while we were there. As if we were being watched. And once we left, the sound was recorded again.
Kyuu's Analysis
It is highly probable that some entity residing in the ancient ruins is deliberately obstructing the investigation. Simple echo phenomena cannot explain this. Records will be maintained to identify the mechanism of occurrence.
