Remnant

It is believed that Remnant is a pure and complete form of frequency energy, and the information it records can transcend time and space to exist in a stable form.

Sources of Remnant Energy

The Etheric Sea contains condensed Remnant Energy, which consequently leads to the creation of new Tacet Fields, as well as the phenomenon known as Retroact Rain.

Transdimensional spaces where Remnant Energy is abundant are known as the Sonoro Spheres (Chinese: 索诺拉). The Sonoro Sphere is an important source of information for humanity to understand the history and civilization of The Lament.

Applications of Remnant Energy

Tacetite is substance that can permanently hold Remnant Energy, and has been crafted into weapons that can damage Tacet Discord. Similarly, Resonant Calcite is an excellent conductor of Remnant Energy.

The Shorekeeper is an entity of high-purity Remnant Energy crystals.

Trivia

@Baizhi's Resonance Spectrum Pattern shows a certain level of similarity with the fluctuations of Remnant Energy.
