Warrior
Your standard warrior-type character. Carries a sword, axe, or whatever. Anyone can be it. May or may not have magical abilities, though any magic would surely be fit to his style. For example: A warrior's magic abilities may be to speed up his attack, stomp his foot and cause a small earthquake beneath his feet to make his enemies uneasy for a moment, etc. It is unlikely he would be able to cast fireballs, ice blasts, etc.
Mage
Your standard mage-type character. They can control magic from 10 different elements of magic: Fire, Water, Earth, Air, Light, Darkness, Thunder, Blood, Bone, and Chaos. Blood, Bone, and Chaos are considered "forbidden" arts, and the use of such elements can lead to death if discovered by a "holy" person. Healers (such as priests and clerics) generally fall in this main class, they are considered to be able to mix water and light to heal. This character class is split into three different sub categories.
Word Wizard
This type of mage carries a wand with him at all times. His spells are cast by waving his wand at his target and muttering incantations. A classic example of this outside of Versumi would be Harry Potter. They are known for usually being able to control the the four basic elements (Fire, Water, Earth, Air) along with Light and Darkness. Controlling Thunder, Blood, or Bone magic is extremely rare in these kinds of wizards. The spells they can cast are also "low level" spells, and rarely learn anything high in magic.
Hand Wizard
These wizards move their hands to form the runes of each spell. This allows them to cast their spells with their hands, rather then with incantations and wands. They can control mostly any element, and are generally able to control stronger spells then word wizards can, but still lack the ability to cast "High level" spells. However, the summoning of monsters can be achieved by them, if they are a particular class. For example, a Warlock can summon a few demons to his side, while a mage can usually summon Elementals.
Thought Wizard
The most powerful kind of wizard, but also the most easily killed. While his spells are powerful, to cast a thought spell requires the wizard's mind to be clear of any and all thought. He must then construct the spell circle for his spell in his mind. To do this, his eyes must remain closed, forcing the wizard to ignore all of his surroundings. If not careful, this can lead to death without even knowing it was upon them. This particular class must take 2 posts to cast a thought spell. One for the preparation of the spell, and another to actually cast it. This wizard, however, specializes in Area of Effect spells (i.e. doing a lot of damage in a large area, such as summoning fire from the skies to consume your enemies). Extremely high level spells will require a third post to be made as an extra "preparation" post. For more info on this PM a guild leader.
Rogue
The rogue, or thief class, specializes in stealing, sneakiness, and assassination. There are no true sub-classes for this, but an "assassin" class would be required to be a rogue. They generally carry many daggers, all concealed well on their person. Their magic generally involves the darkness element, and aiding in their sneaking around. They sometimes also carry poison weapons.
Please send any further questions to a guild leader. Thank you.
