The art of wizardology extends back to 1256, where the first wizard arrived at Lithilen. Since then wizardology has grown but was never a very popular career to pursuit.
To be a wizard, the first requirement is to be pure human and a man (females study witchery). Elves had their own type of magic that conflicted with wizardology. Other races had their own type of people similar to wizards (Example: Shamans). The first step of wizardology is rather dull with lots of memorizing and reading to do. Afterwards, in order to actually gain magic, there was the need to kill a demon. The more demons you killed the more magic you get. The bigger the demon, the purer the magic. But killing demons was a dangerous task and many beginner wizards, if not scared off by all the reading and memorizing, stopped at the demon killing part. One might think that why not killed a demon first and then memorize spells? But the problem is that many people jumped to readily to harder spells after gaining magic and died in attempts to cast these spells. Then life was continued like that, more learning and more power.
Magic, being the potent energy it is, needed to be constantly replenished, meaning constantly defeating demons. Doing this was rather tiring and some wizards after deep studies formed the arts of dark magic, a more sporadic and harder to control, but more powerful and easier to gain type of magic. Instead of killing a demon, if you paid tribute to one and ask it to lease its power to you, as long as you could wield it (if you couldn’t, you would burst into flames) then it was a strong source of energy. Much more easier than the normal route of ways.
Some side effects of wizardology:
Prolonged life - as long as you’re not outright killed, you’re basically immortal.
Extremely good memory.
