Through various means, often meditation, a wizard may insert a prepared program in his brain that once activated will instantly shape motes of aetherial energy into an effect, commonly called a 'casting a spell'. The spell will be tied like a 'password' to a word, phrase, gesture, whatever the hell the wizard wants, though a careful wizard may combine several things to prevent accidental discharge.
Their two particular disciplines of Spellcraft, the craft of preparing said spells. Their is the Evocation Discipline, setting up more of a temporary mental construct in the brain that disintegrates upon a single use. It quicker and easier to build and allows for broader customization, but the wizard needs to rebuild his arsenal after every use. Then their is the Invocation Discipline which has the Wizard lay a permanent construct in their mind. These take time to create however and take up 'room' in the mind, so customization is limited, but the wizard has that spell for good and never has to worry about not having it.
The Evocation Discipline creates bullets with the Wizard as the gun and the Invocation Discipline creates guns with the wizard providing bullets.
The suffix '-mancy' comes from an old word for 'Magic' (Because we get to make up our own language.). Therefore, Fire Magic is Pyromancy, Ice Magic Cryomancy, etc.
The suffix '-urgy' is the real world proper suffix for a discipline of magic, Pyrurgy, Cryurgy, etc. Doesn't slip off the tongue as well.
Until we decide what, I'm using '-mancy' and I'll go back and edit as necessary.
Sorcerers are specialist wizards, those who get '-mancy' appended to their titles somewhere. The practice of Sorcery is similiar to Evocation and Invocation, the Sorcerer has built a mental infrastructure that allows for easier casting of certain kinds of spells. But Sorcery is not a third side to Invocation or Evocation, in fact it can help either or. It is more loose and less well-defined, covering a whole range of similar effects rather then a single specific one. It is also based on ideas, thoughts, emotions, beliefs, making it part Mysticism just as much as it is Wizardry.
Their are Mystical side-effects, but not the ones you might expect. Fire, for example, is closely tied to the ideas of rage and passion. Pyromancers control fire and their disciplines ties them intro controlling their temper and passion better as well. The idea of a blind or forgetful seer is popular, but most seers find all their senses, including sight, and their memories actually sharpen. On the other hand, their are disciplines more Mystical then Wizardry that allow sacrifice fore great power, such a pyromancer sacrificing his ability to control his temper for greater power over fire or a seer sacrificing his sight or his memory for increased ability to accumulate knowledge.
Although, to get these side effects, one must be a sorcerer pyromancer, rather then just a pyromancer. A pyromancer is anyone who who practices fire magic and some do so exclusively. A sorcerer is someone who has gone through mental surgery to actually attune their minds better to fire magic.
Biomancy The Medicine Man's Magic
Biomancy is a complicated disclipine based on several other disciplines, circling entirely around all the functions of the body. Aquamancy is a big one, but so is electromancy and geomancy, divination is incredibly important, but their are also spells taken from pyro and cryomancy and even necromancy has found a place in it and more. It requires hefty knowledge of the anatomy of whoever you're working with. This is called Elegant Biomancy, and is more reliable and less energy intensive then its cruder cousin.
Greater Biomancy pumps pure Life
into the target, giving them regenerative abilities. It's a good kind of magic if you need something quick and stupid before Elegant Biomancy can be applied or before it needs to be applied. A good Biomancer practices both and applies them as necessary.
Biomancers are not all healers but to practice Biomancy, at least Elegant Biomancy, means you have moved beyond the title of 'Sage' as a scholar of any one discipline may learn but have combined several disciplines into one greater discipline and earned the title of 'Doctor'. Of course, the creatore of the dragons, the dire animals and the ogres and other such creatures were all Doctors of Biomancy and they would not be called healers.
Those who practice Greater Biomancy alone are called 'White Mages' or 'Nurses' (They have similar uniform either way) and while generally valued for their skills tend to be looked down upon. Their is a stereotype that they be women most of the time.
