The Magic of Imarel - by T.A. Saunders ©2009, revision v2.9, 12.16.14
To understand the magic of this world, one must first define accurately what magic is and how it exists in the world. Magic, as it is defined on Imarel is the result of Mana being channeled by a being through one of three methods of spell-casting, then use this channeled magical power to call into effect what it is the spell is supposed to do, through force of will.
Mana is the name given to the ambient arcane energy that exists naturally in the world. So long as this ambient energy exists, spells can be weaved and items can be imbued with arcane effects. Without this arcane force, spells would simply cease to function regardless how much sorcerous knowledge an individual might have. While Imarel is abundant in Mana, it is a finite resource. At some point in the distant future, it has been speculated that it may well run out.
There is also different classifications of Magic. Arcane Magic is the physical drawing of cosmic forces from other places, using one of several casting styles to bring about the desired effect. Mystical Magic is the drawing of those same cosmic forces, except it is the chosen deity, demon, etc. of the caster that empowers the effect, rather than a direct evocation from the caster. Divine Magic involves no drawing in of power by the caster, but rather relies on the caster's deity, chosen demon, etc. to both grant the use of those powers then infuse their worshiper with the power to call said magic forth.
Because of the subtle differences, bonuses that effect Arcane magic will also affect Mystic, but not Divine and bonuses that affect Divine will also effect Mystic but not Arcane. While Mystic magic would seem the most potent, it also requires the devotion a priest would normally have from the mystic caster and a chance to be struck down, cursed, etc. for its misuse.
