A-Type

The A-Type is one of the source types of the Fons Type classification system used by the Academia Ars Magicka et Mundana.
A-Type (also called Arcane Magick) is classified as any Magick which stems from a wielder's own soul and which uses inherent qualities of their character to manipulate the world around them.
Some A-Type wielders ability to cast Magick seems to be based on their logical-mathematical intelligence while others seem to use other personality traits like their charismatic force to channel arcane energy.
