Demons

Creation
Demons are manifestations of evil influenced magic, normally caused by an imbalance of nature in a certain area. These demons are ranked in level of magic and relative power, from one star to seven stars, one being the lowest and seven being the highest. One star demons are mindless beasts, appearing in many varying forms, from centaur like chimaera to bat-tiger hybrids. These demons are mostly intent on causing havoc and consuming large amounts of magic that causes an already deteriorating ecosystem to go further into decline. Seven star demons, on the other hand, are mostly giant creatures that have the intelligence of humans and often have an inclination towards a certain act of evil, before they are dispersed naturally by the cycle of magic exchange. These demons have been grouped by researchers in the Guardians into seven different "species", according to the seven deadly sins of man:
 * Lust- Water
 * Gluttony- Lightning
 * Greed- Wind
 * Sloth- Earth
 * Wrath- Darkness
 * Envy- Ice
 * Pride- Fire

These groups have many subgroups, and different families, etc. But, the groups seem to have an affinity for a certain element, as shown above.
