Waveworn Phenomenon

"The anomalies that occurred after the Lament, including the formation of Tacet Fields, Etheric Sea, Retroact Rain, and gravity loss. These are collectively called the "Waveworn Phenomena" - and the Lament was the start of it all." @Yangyang

Waveworn Phenomenon (Chinese: 海蚀现象, "Coastal Erosion Phenomenon") is a collective term used to describe anomalies caused directly by the influence of The Lament in Solaris-3. These phenomena can vary in scope from minor distortions to widespread ecological and psychic collapse. They are distinguished by their chaotic nature and the presence of Tacet Discords.

Data Entries

As noted in Post-Lament Anthropocene: Comprehensive Mirror for Historians, The Lament unleashed waves of destruction that had an "erosive" effect upon Solaris-3. This anomalous "erosion" is not only physical but metaphysical, distorting memory, structure, and causality itself.

General Occurrence

These are the generally identified types of Waveworn Phenomenon in Solaris-3:

Tacet Discord Outbreak

Tacet Discord Outbreak (commonly referred to as a TD Outbreak) is the sudden emergence of Tacet Discords—sentient beings formed from residual chaotic frequency energy under the Waveworn Phenomenon. During an outbreak, Tacet Discords proliferate in areas with intense frequency distortion, instinctively feeding on surrounding frequencies to evolve. Their amorphous forms and behaviors are shaped by the types of frequencies they consume, often leading to unpredictable mimicry and regional disruption.

Tacet Fields

A dangerous zone born from the Waveworn Phenomenon. Its most distinctive feature is the white Resonance Cord in the center, marked by a giant Tacet Mark. In addition to hazardous Tacet Discords, the area is also rich in precious materials.

Tacet Fields are a form of geographical Waveworn Phenomenon, and are widely believed to be where all Tacet Discords originate. Reverberations fill the air in these locations, linking the world to an unknown space through a white Resonance Cord. They are identifiable geographic anomalies, marked by the visibility of the Etheric Sea and a large, cross-shaped Tacet Mark stamped into the terrain. Tacetite formations erupt from the ground around the mark, and the area exhibits localized gravitational distortions—ranging from floating debris to warped terrain as depicted in Qichi Village. These zones are typically surrounded by Tacet Discords, which linger near the field's perimeter even during periods of inactivity. In some cases, Retroact Rain can also occur in such areas thus creating Phantoms within the vicinity.

Tacet Fields form through the convergence of the Etheric Sea and enter an initial Dormant phase of relative stability. Rapid formation often results in a longer Dormant period and the eventual emergence of more powerful Tacet Discords.

Tacetite

Tacetite is a rare substance discovered during the study of Waveworn Phenomena, known for its ability to permanently contain Remnant Energy. This property makes Tacetite a valuable material for crafting weapons used by Resonators against Tacet Discords. It is most commonly found within transdimensional zones rich in Remnant Energy, known as Sonoro Spheres. They are also occasionally found in clusters around Tacet Fields.

Gravity Loss

Gravitational anomalies have been consistently observed in regions affected by Waveworn Phenomena, with notable instances recorded across Solaris-3. Prominent examples include areas within Qichi Village, the Port City of Guixu, Norfall Barrens and the vicinity of Avinoleum.:

Retroact Rain

First depicted in Chapter I Act V: Rewinding Raindrops, Retroact Rain is a documented Waveworn Phenomenon composed of condensed Remnant Energy originating from the Etheric Sea. Due to the inherent property of Remnant Energy of recording events across time and space, exposure to the rain often triggers vivid illusions of past events. Individuals with strong emotional ties to the affected location are more susceptible to intense hallucinations. While generally non-lethal, Retroact Rain acts as a potent attractor for Tacet Discords due to its high Remnant Energy concentration. The presence of a Threnodian can further amplify the phenomenon’s effects as seen during the Battle Beneath the Crescent with the Threnodian, Ovathrax. Notably, the frequencies of individuals who perish within the Retroact Rain become permanently embedded in the rain itself.

The Dark Tide

Regionally occurring in the city-states of Rinascita, The Dark Tide is a documented Waveworn Phenomenon that manifests as a dark, swirling mass of clouds that gathers and eventually breaks, pouring down in torrents like a waterfall. Whenever the Dark Tide occurs, it spawns Tacet Discords, and the area around its point of origin becomes a new Tacet Field. Additionally, it was described as a mechanism of mass assimilation and indoctrination associated with the Threnodian, Leviathan. The Dark Tide initially spreads through direct contact, converting organic life into vessels that emit continuous hymns. These transformed entities—often described as the dead who "grow mouths and sing hymns, day and night"—function as agents of psychological contagion, spreading madness and perceptual corruption. Minor manifestations related to the Dark Tide were also introduced in Septimont, specifically the occurrence of the Blightcloud, the High Tide, and the Tidal Blight.

The Sea Fog that occurs around Rinascita is also considered as part of the Waveworn Phenomenon that is local to the area.
