Magicka influences the living and the dead, the real and the unreal. It may be everything or nothing at all - but it has always existed and will be with us forever. Magicka is constituted by the spiritual energy of the world; its own nature is linked to the Flow of Souls, although it would be more precise to say it is one of its aspects. Magicka springs from spirits and reality itself. In a way, it can be thought of as the shadow of existence; it does not respond to the laws of physics or logic, but it alters the world as it pleases.
