Event Storage

An ability of the True Ancestors who are the planet’s sense of touch. They store everything that was brought up on the surface of the planet, both conceptually and physically. A storage of every creative work on the planet’s surface ——— A confiscation of “Texture.”
It is an unusual ability that would be on the level of “Authorities” if one was to speak about Divine Spirits, but it is a function possessed by the planet so rather than a Skill it is a System. The sphere of gravity that appeared under Arc’s feet after she became a Luminous Body has a scale enough to store the Textures of the whole Earth.
