The story of Wuthering Waves unfolds on Solaris-3, the third planet in the solar system. It all begins with the first 'Lament'. New things emerge, the old rules are invalid, and unprecedented disasters are raging on the earth. In this new world where destruction and rebirth coexist, humans are holding the unyielding spark of civilization, and are about to resist the new wave of unknown never ending crises.

Indeed, ‘The Lament’ is the general term for all the disaster trends in Solaris-3.

"The tide never stops, the Lament never rests."

The anomalies that occured after the Lament are: the formation of the Etheric Sea, Tacet Fields, Retroact Rain, Blizzard and gravity loss. They have an erosive effect on the world of Solaris-3 and are collectively called Waveworn phenomenon.

The Etheric Sea is a special type of abnormal weather phenomenon.

The sky appears to resemble an upside-down ocean surface. Typically, when the Etheric Sea phenomenon appears, a Tacet Field is about to form on the ground.

These Tacet Fields are fields that arise in unpredictable places, however there are individuals, among those known as Resonators, who can detect the formation of Tacet Fields by reading so-called Streams, i.e. flows in the air, as Yangyang does.

Tacet Fields are believed to be the place where all Tacet Discords materialize and gather. These places are characterised by a deep cross shape Tacet mark on the ground. Frequencies fill the air, connecting our world to an unknown space through White Resonance Cords.

Since we are talking about oceans, these endless repeated phenomena can be called Tides.

During these tides, creatures known as Tacet Discords emerge from the Tacet Fields. By definition, they are entities formed by the residual chaotic frequency energy of the Tacet Fields, having an indefinite shape.

But what are frequencies in the Wuthering Waves world?

We have said that when the Lament occurred, the laws of nature changed. Well, because of the Lament now the world is built around the concepts of sound and frequency.

Indeed, Yangyang tells us during the story that: "Everything in our world is made up of frequencies.”

The most important concept comes now: There is a view in the academic world that due to the Waveworn Phenomenon, matter, information and energy are all reduced to the vibrating frequency.

It must be seen in a different way than we are used to. In fact, it can take on a physical form.
