The Burning Crusade was the introduction of new and unique titles into World of Warcraft, and the Champion of the Naaru was one of the first to be achievable by players.
The title was originally added in patch 2.3.0, however, it is available during phase 1 of classic Burning Crusade as the quest to achieve it is already in the game.
The title reads <Player name>, Champion of the Naaru.
How To Earn The Champion Of The Naaru Title In The Burning Crusade Classic
The title is very straightforward to get although it can be a bit time-consuming, like many things in the early World of Warcraft.
Players are required to complete two quests, which simply are the Serpentshrine Cavern, and The Eye attunement quests.
The Cudgel of Kar'desh is the quest to complete Serpentshrine Cavern's attunement.
Followed by Trial of the Naaru: Magtheridon, the thirteenth quest in The Eye attunement questline, which will then award the Tempest Key.
Once both quests are complete, the player will be awarded the title, which can be selected in the character tab.
For many players, they will accomplish this naturally, as raiding is the main draw to the game for many and these quests are required to complete phase 2 raids.
The acquisition of this title was removed upon the release of Wrath of the Lich King so players who are collectors will want to earn this title before the end of The Burning Crusade.
