Class 1: Mage.
Mage, also known in this universe as a magician, sorcerer, sorceress or wizard, is basically a person who follows the path of magic. They may specialize in magic, or may be learning it. Mages perform magic by either casting spells using a wand, by performing rituals, or by creating potions. Magic, whether it be spells, or rituals, work by channeling the inner life force called mana. Magicians, when young, are taught the art of using their mana in moderation, as overuse may cause unconsciousness, exhaustion, or even in some cases, death.
As a young magician, the mage is made to go through several years of training. After series of tests, if the mage manages to pass, he/she is given the license to perform magic freely around the land. Usually training starts when the person is 13, the time when children are supposed to decide their paths. The training ends when the child is 21. A mage is forced to study all kinds of magic, but they may excel only in a few. (Think of it like this, in school, you are forced to study Mathematics, English and Science, it is possible that you may be very good at Science, but not good at understanding Mathematics)
A lot of a Mage's ability also depend on their age. As a young magician, you may be lacking in the experience department, but you have a lot more mana to spend. As an older magician, you may be wise and have experience, but your old age limits your mana usage.
In order to become a mage, a person has to be really patient, to learn the various spells. Magicians aren't scared of failure, as failure makes them correct their mistakes and move forward. A mage also needs to be extremely patient and have very delicate and precise movements, they cannot be of the clumsy kind. Mostly, mages born into families practicing magic have more magical powers than those who aren't. As a magician, the user is better at ranged attacks (ie, attacks from a distance) than melee or close quarters combat.
Notable magicians are Merlin and Magus. Merlin is the founder of all types of magic, the one who publicized it in the land, while Magus is the author of the 'Magia Liber', the most powerful book on magic in the world. It contains all spells that have ever existed in the world, and some dark ones as well, also the reason there is only one copy of the book, locked away deep inside a hidden place.
Types of magic
Ignea Magica/Red Magic: Red magic is basically offensive magic that does basic amounts of damage to other mages/creatures. Most spells in Red magic are related to fire, but Red magic is any kind of magic involving offensive spells. This type of magic draws its power from the user's mana. The most basic spells in this type of magic do not require a lot of mana, while more powerful spells may need to draw more power. To use this power, a mage normally needs a sturdy wand.
Magiae Naturalis/Green Magic: Green magic is magic related to nature. Mostly this type of magic is related to defensive spells, although there are exceptions. Green magic may be related to drawing mana from plants and animals, or even sharing their resources with them. Some may also involve defending oneself using the surroundings, or attacking an enemy with nature. This kind of magic requires low to moderate mana usage. Magicians excelling in this kind of magic will often carry a wand, and also carry herbs with them.
Magica Sanitatis/White magic: White magic is magic related to healing or holy power. This type of magic is really powerful, but draws upon more mana than others. This type of magic focuses on healing injured beings/persons, or may also be related to drawing power from holy objects. For this magic to work, a mage merely needs to grasp the concept of holy beings such as 'God'. To work this kind of magic, Mages need to be skilled in rituals and potions.
Magica Mortem/Black Magic: The darkest kind of magic in the land. It is forbidden to learn or practice this kind of magic, and learning it will make the user suffer severe punishment, mostly death. This sort of magic is related to death and spirits. It can only be used by magicians who house pure evil in their hearts, and have cruel intentions. It draws upon great amounts of power from the user, therefore only the strongest magicians can use this magic. Powerful spells in this sort of magic include resurrecting dead souls and killing people to gain power. In order to be skilled in this sot of magic, mages need to be skilled in rituals.
