Authority (権能, Kennō?) is a classification of special abilities possessed by the likes Divine Spirits and the agents of the world like True Ancestors and Great Mother/Father class Fairies.
Authorities are an ability of category unique from the likes of Codecasts, Skills, and Noble Phantasms. They are on the level of creating a world, this includes event shifting, time-flow manipulation, kingdom-building, and other such powers of that level. While normal Skills "achieve a certain result based on some logical process or principle," Authorities "realize a result simply because the user has the right to do so."
The usage of Authorities existed primarily within the Age of Gods six thousand years before modern day. As of the Common Era, the advancement of human civilization has rendered Authorities unnecessary, rendering them a relic of the prior age. Divine Spirit Servants possess their Authorities, but the usage of their Authorities in the Common Era requires compensation in the way of strain and damage inflicted on them. Those that gain full control over the Moon Cell reach a level of power that is Authority class.
Authorities used by beings like True Ancestors, the "planet's sense of touch," are classified as a "system" rather than a "skill." The Functionalities (機能, Kinō?) of the Twelve Machine Gods are similar to Authorities and are referred to as such.

Kennou. Authorities are special abilities that fall into a different category than Codecasts, Skills, and Noble Phantasms.
An Authority is a power that is on the level of creating a world, and includes things like altering events, time-flow manipulation, and kingdom building.
Authorities existed in the age known as the Age of Gods, which was about 6000 years ago, but after entering the Common Era human civilization advanced to the point where Authorities were no longer needed, and so Authorities became a relic of the past.
Normal skills achieve a certain result based on some logical process or principle, but Authorities realize a result simply because the user has the right to do so.
A God Spirit Class Servant should naturally possess Authorities, but to use them in the modern age requires a corresponding compensation to be paid (involving strain/damage inflicted on the user).
In CCC the one who swallowed up Moon Cell has reached a level of power that is Authority class.
 Tsukihime Material I - GLOSSARY: Event Storage, p.101
An ability of the True Ancestors, the planet's sense of touch. The conceptual and physical storage of things reared on the planet's surface. Every creature that has appeared on the face of the planet——it is something that requisitions textures.
In terms of Divine Spirits it's an ability on the level of an Authority, but since this an Authority of the planet it is a 'system' rather than a 'skill'. The gravitational sphere that appeared at Arcueid's feet when she had become an Astral Body was of a scale great enough to store the entire planet's texture.
