Anti-magic is the inversed form of magic, which was studied by the old elementalists in the Temple of Elementalists. As it is a rather dangerous topic, the old mages tried to hide it from the public.
Anti-magic was the cause of the death of many old elementalists.
Even though the knowledge of this magic was highly secured, both Cyrus and Velius re-discovered it and tried to get the forgotten information.
The condensed form of it, the anti-magic crystals, is popular in the world of Admantris, both to protect against magic and to control mages with it. The anti-magic pendant is an example of its use.
As the magic in the world of Cendric has a color, Anti-Magic has the color black. This results from combining all types of magic into a white color and inverting it. However, in the game, anti magic appears as dark purple.
