Neural Magic

At its most basic form, magic is either Elemental or Neural. Elemental magics stem from the physical world, and Neiral magic is based in how that world is perceived and interacted with. Practicing the latter will, however, get you killed on sight.

The Purge
In the first century, an event known as the Splitting of the Tribes was marked by a week of terror and bloodshed that spread across all of Itaedia, and in many ways helped to unite it. These events were triggered by a widespread fear of those who weilded magic, and it was only through the campaigning efforts of many elemental mages that magic use wasn't destroyed entirely at this point. Great debates were held throughout the tribes of humans, yoonda, nygari and skridae, discussing the possibility of these races---who at that time were split into many warring tribes---uniting against those who tormented and exploited all peoples through the abuse of magic.

Healing Magic and Carnemancy
Healing magic, is, obviously, not banned in any part of Itaedia, and remains the most widespread and well-known of all magics. However, those who practice healing magic are under very close scrutiny, lest they show any signs of progressing into Carnemancy. This was one of the most feared of magics and, though it could be a great tool for healing and miraculous ways of improving living creatures, its practice in any capacity warrants death.

The Five Banned Magics
The five following magics, either partially or completely, have been banned throughout Itaedia, and the practice of them warrants death without trial in most societies. This is because it is impossible, during a trial, to be sure the accused itsn't swaying the decision in their favor through sinister means.

Sound Magic, Caneremancy, and Frangoism
Frangoism, from the word "to shatter"

Healing Magic, Carnemancy, and Scindamism
Scindamisn, from the word "to rend"

While in the erliest stages, this magic is among the most beneficial to mankind, it quickly becomes a terrifying way to torture creatures, and to sustain their life throughout said torture. Bones can be broken and rearranged at will, flesh can be molded like so much clay... on many ways, the victim is unwillingly turned into a Caeder Crawler.

Touch Magic, Punctumancy, and Vesanism
Vesanism, from the word "to go mad"

Sight Magic, Praestigiamancy and Dubitarism
Dubitarism, from the word "to doubt"

Taste/Scent Magic, Pheremancy, and Tradoism
Trado, "to betray"

The practicioners of Tradoism were among the more difficult to track down, as they operated entirely through pheremonal manipulation, and were able to cloak themselves in all a manner of disguises, even make the Vykandri believe they were hunting themselves down. Of course, there are ways of getting around these illusions, as with all things the Vykandri oppose.
