Not a true magical tradition, Hedge Magic (or "natural magic", as it's more politely called) involves the brewing of natural remedies and potions, using the natural magic in the world through herbs and roots to bestow it's effects. Someone may be an Herbalist and follow another Magical Tradition.
Practiced by the Engro, Elves, and Frost Dwarves, druids draw their power from the natural energy surrounding the earth, plants, and animals. Humans do not understand the natural world enough to become druids. Druids are powerful in the wilds, but suffer within artificial or worked structures, which block the natural energy fields.
Elementalists must decide to belong to the Convocation of Elementalists or remain a Free Agent. Elemental Mages must choose a single element to serve. Fire has weakened since the Blizzard War, but is still strong in the warmer climes. An elementalist's power comes from the bound spirits of these raw elements. As Elementalists grow in power, they may slowly learn to master other elements as well, albeit at a steep price. All races practice Elementalism.
Heahwisardry is taught solely in the Magocracy, and then only to the ruling class. Heahwisards are bound to their magical staves through a complex ritual, and it becomes both symbol and focus for his power. A Heahwisard may only own one such staff in his lifetime. Casting without a staff is possible, but extremely difficult, and mages who betray the Magocracy have their staff ritually broken (no easy task), depriving the rogue mage of much of their power.
These controversial mages draw upon the power of the Hellfrost itself, converting the cold and frost into mystical energy. Though some have sided with the forces of the Hellfrost, most are simply making the best of what nature has thrown at them. However, rumors and prejudices run deep, and all Hrimwisards are treated with deep suspicion.
Rune Magic is only used by the Frost Dwarves, though it is recorded in ancient Dwarven texts that the Saxa once knew the art. If this is true, such knowledge must be long lost, for only the oldest Saxa songs and poems ever reference the art. This ancient magic uses carved runes as the focus for weaving magical threads into a cohesive spell. Rune mages must prepare runes for each casting, carving or scratching them into objects.
Song mages, or "Skalds", are sorcerers who work their magic through the power of song. The art is extremely ancient, and is found amongst all races, though the Anari skalds became rare when they began writing down their epic tales. Skalds are not just spellcasters, but storytellers and poets, able to recount epic poems and stories from memory. Some play instruments, but most simply use their voice to enthrall their audiences. Skalds are popular with commoners and nobility alike, and can often find a warm bed and a hot meal in exchange for their tales.
Alchemy is not a magical tradition, but a way of using a magical tradition to craft limited-use magical items such as scrolls, potions, wands, and the like. One must practice a magical tradition in order to practice Alchemy.
