Elemental affinity

Some humanoids are born with a connection to one of the elements. These individuals are called elementals. Elementals can sense each other, though only when within the radius of a star, thus excluding nighttime and the shadow between worlds.

There are various levels of affinity an elemental can attain, either through innate gift or hard training: The higher levels require a much larger amount of elemental affinity for fire and frost elementals than for ether elementals. This balances out the rarity of such individuals considering that ether elementals are much rarer than the other two in the first place.
 * 1) Demi-elemental: Not considered an actual elemental. Includes people who are able to emanate moderate amounts of heat, cold, or healing energy. Garth is an example of such an individual, although he is highly unique for having affinity for multiple elements.
 * 2) Adept: The lowest tier of elemental. Capable of conjuring up fire, frost or ether with moderate effort. Might need elemental gems to accomplish more demanding feats. The vast majority of true elementals are of this category.
 * 3) Elemental: Can conjure their element with no thought or motion behind it, and is able to perform feats for which a conjurer would need a large amount of storage gems with ease and regularity. Their connection to their element is so strong that they don't suffer any negative effects due to exposure such as burns or frostbite. Capable of sensing and manipulating their element even from a distance. The Wanderer is an example of such an individual.
 * 4) Cosubstantial: The highest tier of elemental. Completely one with their element. Capable of performing feats the previous tier could only accomplish with tremendous, possibly fatal effort, with mindblowing ease. Tends to get a bit 'lost' in the power and the immensity of the experience; insanity usually ensues, and they usually end up identifying more with the element than their race. Flame is an example of such an individual. There is reason to believe Hël may be an elemental powerful enough to achieve cosubstantiality, who however is aware of the possible risks and has the willpower to refrain from keeping in (as is in line with personality traits common in frost elementals). Cosubstantials are frequently immortal.
