Scio Occultus Res
The Quiescence, or the Lie, is the mages’ name for the curse placed on the Mundane World when the Exarchs conquered the Supernal World and severed the connection between the Supernal and Mundane Worlds, creating the Abyss. The Quiescence prevents most of the folk in the Mundane World from understanding or accepting the existence of magic. Most mystical theoreticians believe that the Abyss is both the medium and the power of the Quiescence, a semi-intelligence non-world that somehow reaches through the minds of the Sleepers to impose the Exarchs’ ban against magic and belief on the world, producing Paradox in the presence of Vulgar Magic.
Quiescence works through the perception of Sleepers, eroding magic through a force that mages call Disbelief.
