Magician

Basic Knowledge
Magicians are powerful human-like creatures that learn and practice any kind of magic. Magicians usually specialize in the type of magic that they were either born knowing or learned first. Some Magicians are born as Magicians, this is caused by a genetic mutation. Other Magicians, "Human Magicians", used to be humans but they trained for several years focusing on one type of magic until they became Magicians.

Powers that Magicians can have
Literally they can practice anything. Usually though Magicians specialize in one type of magic.

Example 1: Lady Clare was born knowing the element water, so she specializes in water. Advanced water controllers can pull water out of thin air, and during full moons they can move the water inside other people.

Weaknesses of the species
There is a major problem with being a Magician. Sure you can use any type of power as long as you learn it, but Magicians can't use their non-specialized powers for too long. The max amount of time a Magician can go using their non-specialized power is only 15 minutes in 24 hours! If a Magician goes longer than that, they use up all their magic and pass out for 24 - 48 hours. Another weakness that is only for Human-Magicians is that they cannot be bitten by either a vampire or a werewolf. If this happens then the Human-Magician looses all their magic and turns back into a human again and usually turn into whatever they were bitten by.

Life Span
Magicians are immortal and can live forever if they aren't murdered, get extremely sick and never recover, or commit suicide. The youngest known Human-Magician was converted over when he was only 13. (See Kyle White) The oldest living Magician is Lady Clare, there used to be older Magicians, but Lady Clare had them killed so she would be oldest.
