Runes are the alphabet of magic, combined to make spells.
Exerpt from the Book of RunesEdit
“..It is theorized that at the beginning of the world, magic was abundant, and people were able to use it more freely. However, because such free use was not reliable, people developed techniques in order to be able to control magic. These techniques came to be called rune-casting, and runes were created for that end. Runes became extensions of will and confined the magic into specific energies to perform specific tasks. No one currently alive really understands exactly why people have affinities, just that people do.”
“Runes are the alphabet of magic in the world. Everyone has the capacity to use runes, though some are better than others.
The ability to use magic relies on both the caster’s connection to the celestial plane (“affinity”) and the caster’s will (“will”). Affinity is something relatively stable–though it can increase on decrease on rare occasions), while will is something that can fluctuate depending on the person’s personality, experience, fortitude, and stage of life. For the most part, a spell caster’s ability to improve, given a strong affinity, is only determined by his or her own will.”
