Wizards

The classical arcane spellcaster. Known to be power hungry and not much fun at parties. For some reason too many elves take up this lifestyle even though their frail charisma makes them less well suited to being and aventuring wizard. Wizard are definitely not people you wish to be on the bad side of if you like waking up the same shape you went to sleep in. Handy for adventuring parties as artillery pieces, buff machines, and the occasional needed skill check roll that your dwarven cleric can never seem to make. They are also noted for making many of the handy magical items that litter most worlds and the occasional troublesome artifact.
Another side effect of the existance of the wizard, is that for some reason inexplicable things seem to happen such as underground dungeons having breathable atmospheres, thriving ecosystems and a complete lack of noxious fumes. Thus when something inexplicable happens, it is common to say "Wizards did it."
When asked if they ever did anything useful, a wizard pulled a coin from my ear and then disappeared.
