Wizard

Wizards are magical beings similar to witches, they can be good or evil, just like witches.

They have their own powers (their powers are usually considerd rare at "witch world",on other side powers of witches are probodly rare at "wizard world") like illusions, levitation, shapeshifting, apparition (This is a teleportation of wizards), invisibility, transformation, glamouring, conjuring and some others, they are wery skiled potion makers, future tellers (see Divination) and spell, charms and curse inventors.

That's probably the main reason why the Source of all Evil wanted them all dead.The Source killed many wizards but not all. So now when the Source is dead, they have oppurtunity to come back.
