Aura
Aura or Auratic energy is a mystical form of energy inherent to most lifeforms on Zairis. Naturally, it tends to manifest aligned to one of the twelve auratic elements, but with manipulation, it can be converted to other forms such as unaligned 'pure' aura that is utilized in the auratic arts referred to by practitioners as Disciplines.
Elements
A naturally generated Aura (not precluding edge cases such as Aura blank) is aligned to one or more of elemental types, each of which attunes its source to an aspect of the world by allowing it to manipulate or generate it. The elements are as follows:
Air | Water | Earth | Fire | Light | Darkness | Thunder | Ice | Metal | Grass | Blood | Void
Elemental magic is the most fundamental form of spellcasting in Zairis, since it doesn't require the precise manipulation of the caster's Aura to filter its alignment out.
Notably, the Blood and Void elements are considerably rarer among the civilized peoples than the other elements, with Blood being found in less than 3% of the population and Void in less than 0.5%.
