Four years have passed since the aftermath of Warcraft III: Reign of Chaos, and a great tension now smolders throughout the ravaged world of Azeroth. As the battle-worn races begin to rebuild their shattered kingdoms, new threats, both ancient and ominous, arise to plague the world once again.

World of Warcraft is an online role-playing experience set in the award-winning Warcraft universe. Players assume the roles of Warcraft heroes as they explore, adventure, and quest across a vast world. World of Warcraft is a "Massively Multiplayer Online Role Playing Game" which allows thousands of players to interact within the same world. Whether adventuring together or fighting against each other in epic battles, players will form friendships, forge alliances, and compete with enemies for power and glory.

The Priest class is the master of healing and hate control. Other classes such as the Shaman, Druid, and Paladin can heal, but not as well as the Priest. The Priest can also resurrect dead players along with the Shaman, Druid, and Paladin. The Warlock also has the ability to resurrect, through the use of soul stones. The Priest has some buffs that can help party members. The Priest can even take control of humanoid monsters at higher character levels.

Priests lead the many faiths spread throughout the disparate lands of the world of Azeroth. In Kalimdor, Night Elf Priestesses revere the moon goddess Elune, while Dwarven priests in Khaz Modan deliver the message of the Light to their people. In the ruins of Lordaeron, the undead priests of the Forsaken, their faith twisted and tainted by their tortured existences, spread a dark interpretation of the Holy Light. Regardless of their faith, however, all Priests share in their ability to manipulate the minds of those who turn to them for spiritual guidance.
