World of Warcraft: Deceiver is the sixth expansion of the World of Warcraft. The content of the expansion will feature the return of Kil'jaeden and plans to destroy the Argus and Azeroth.
From the official site:
A long-lost enemy has returned from the Sunwell.
After N'Zoth's defeat, the Alliance and Horde believed that Azeroth was saved and put an end to this evil. But they must fight against the Burning Legion.
The Alliance and Horde continue to ally themselves in defeating the Legion once again, but an old enemy has returned. Kil'jaeden, the Demon Lord and the Superior leader of the Burning Legion, was freed from the Sunwell with the help of Mal'Ganis, who was revealed to be alive. The enemies lead their conflict on the planet Argus, which was thought to have been corrupted by the Legion's demonic power. Now the Alliance and Horde must aid other races and factions to face Kil'jaeden and the Burning Legion.
Player level cap increased from 100-110.
Kil'jaeden is planned to be the final encounter in the expansion.

On Argus, four new playable races will be introduced in this expansion:

Giths - a faction of orc-like humanoids that join the Horde in the expansion.
