Elemental Affinities

The Empty Domain contains a large amount of magic. Everyone is born with an affinity towards one of the elements.

Elements: Common (most people have these)- Air, water, fire, earth
  Uncommon (typically nobles or elites)- Dark, light, electricity, poison
(Although technically still uncommon affinities, dark and poison affinities are seen less often due to the lack of breeding and sometimes the killing off of those with them. On the other hand, a light affinity is seen as a sign of a pure soul and is very desired.)
  rare (High nobility and special forces)- Thunder, force, combination of 2 different elements.
