Seers

"You want to know the difference between a seer and a scryer? The easy answer? Seers see. Scryers look. Don't know how to explain it any simpler than that."

— an admonishment from a Soul magic teacher in response to a foolish question

Among humans, anyone who suffers from unpredictable and/or uncontrollable visions is considered a seer. It is believed that seer visions only reveal future events, but rare occurrences of visions occurring simultaneously with what they reveal have been recorded. Among other races, seers are classified depending on how they receive they're visions.

Elves

Elves have the most variety of seers, as they classify a seer as anyone who has vision or senses beyond the norm. 

malreyv

"dream seer"

Malreyvs are a more common type of seer among the elves, though most only catch glimpses here and there. Malreyvs that take the time to train themselves can enter what's called a malivana, or dream trance, that allows them a small amount of control over their visions. A malreyv's visions are extremely open to interpretation, as the images that appear in dreams are often very fluid and step away from reality.

melyv

 "truth seer"

One of the rarer forms of "seer", melyvs can sense the currents of intent in a person's mind as they speak. No matter what language is spoken, a melyv knows when a lie is being said in their presence, even if they don't understand the words. Many mentalists can learn this ability, but they can be fooled by someone with a well-trained mind. Melyvs cannot be tricked in such a way.

claryv

"far seer"

Similar to human scryers, claryvs have the most control over their visions. Claryvs can actively trigger a vision and choose a location they wish to observe, though what they see is usually unclear. Often, their visions contain elements that require interpretation, such as a blood-red sky over a normally peaceful area.

argryv

"storm seer"

Elven weather-watchers, argryvs are considered the chosen of Argus. They can sense patterns in the air, even those yet to come, thereby predicting changes in weather before they arrive. Argryvs were instrumental in preventing the destruction of several settlements - both human and elven - during the great storm of XX.

floryv

"green seer"

Floryvs are uniquely elves - no other race has anything like them. They are the rarest of elven seers and possess the ability to "speak" to the creations of Florian. Also called "woodsingers", most floryvs apply their gifts to shaping elven homes in the trees of the Wood. Others offer their services to artisans who cultivate herbs and plants used in elven foods and crafts. The most powerful floryvs are responsible for the shaping of the World Trees. The Woodspeaker is the most well-known floryv.

Nelfyns

At the height of their society, nelfyns boasted three classes of what they considered true seers. Because of the gift all nelfyns had to hear the Song of Creation, it was often hard to tell when one had gifts that extended beyond their innate Voice.

falastravi

"star diviner"

Because nelfyns believe stars are glimpses into Ímlæs rather than just guiding lights, stars hold a special place in nelfyn culture and society. To that end, some nelfyns' Voices are attuned to the stars, and they Sing and Listen almost exclusively to their Songs. These falastravi are responsible for "reading" the fates of other nelfyn and determining their path in society as defined by the stars. Only godsingers are considered more important in nelfyn society.

nulistravi

"time diviner"

The most like human seers, nulistravi can Hear not just the current rhythms in the Song, but echoes of future rhythms and Voices as well. This gift allows them to predict the flow of the Song, thus predicting large events such as earthquakes, storms, even plagues and conflicts. However, the echoes are often difficult to Hear beyond the current rhythms, and even the strongest of nulistravi cannot say what is coming with absolute certainty.

karunastravi

"far diviner"

The most similar to human scryers, nelfyn far seers can summon visions of other places. Unlike scryers however, karunastravi can only see what is happening at that moment, and their vision is within their mind, not projected onto a medium as scryers use. Godsingers valued karunastravi as a means of observing the cities and lands they were responsible for in times when travel was difficult or impossible.

THE FIRST SEERS

Brendana Iivanal is credited as the first human seer. Unlike seers of other races that came before her, Brendana was struck one day by a completely unexpected and uncontrolled vision of Divina and her Divine Glass. In the vision, Brendana claimed to have been given a message by the Allseer to guide others as they caught Glimpses of Fate. Since that event, humans throughout history have been struck by sudden visions of events to come.
Among elves, Lordaerel is credited as the first to share visions granted to him by the gods, but due to the scattered semi-nomadic society elves had before he became the first King, undocumented cases of elves with the gift of foresight could very well have existed. Historical tomes label Lordaerel as a ryviinla, a seer possessed of multiple methods of foresight. Though a few other ryviinlas have been documented since then, none have claimed the skill that the ancient King and his heirs possess.
Nelfyns have no figure labeled as the "first seer", since the nature of their foresight is very different from other races. However, the godsinger Aelion Valfalas was the first to display the powers of a falastravi. 
DIVINA & SOR In almost every story about fate and seers, Time's two mysterious children take a great role in the development of human foresight. Despite the legend of Brendana Iivanal, visions are believed to be gifts from Sor rather than his sister. Divina aids more in active scrying.

ACTIVE vs. PASSIVE FORESIGHT Humans are the only race that differentiates between seers and scryers, and students of magic are often dismayed to discover how difficult the latter really is. Seers have no control over their visions (though some have learned signs that one is about to hit), while scryers have to exert their will and magical power in order to see a vision.
