Magic

Magic is the rewriting of reality based on the will of an individual. Every angel and demon is capable of wielding this power while only the most fortunate humans can cast more than a simple cantrip.

Any being with a soul is capable of wielding magic, though the potency is dependent on one's allotted power and connection to the Mother. The weaker the connection, the more difficult it is to cast magic. As a result, most individuals never even delve in the art.

Mages, especially ones that can trace lineage back to the Guardian, combine natural power with intense training. The children of angels also inherited this power. However, as the generations advance, their power weakens and the divine no longer copulate with humans.

Priests are capable of the same feats as an individual possessing divine blood. Children of priests inherit this power just as a child of a mage would, making them the only new source of magical talent in the world of mortals. There have been countless occasions of ambitious individuals trying to exploit this.

Principles
The following are undeniable facts of magical power:
 * Only the Mother can create flawless life. Any attempt by mankind will be corrupt, despite intentions.
 * Protection magic is easier to perform than destruction magic. This is due to the Mother's love preserving her creations.
 * Enchantment permanently takes a piece of an individual's soul.
 * The faithful and the divine themselves claim that this worsens an individual's afterlife.

Forbidden Practices

 * Soul Binding
 * Mind Manipulation
