The subject of this article or section was part of the Gates of Ahn'Qiraj, a world event that heralded the opening of Ahn'Qiraj. This is no longer available as event is permanently over as of patch 3.2.0.
There are twenty different versions of the quest One Commendation Signet. The table below summarizes all versions of this quest. Note that the ten rows with the comment "war effort only" only exist until the end of the Ten Hour War Gate-Opening world event. The other ten quest givers will be active until Blizzard decides to deactivate them for all realms.
For those adventurers who have but a single [Alliance]/[Horde] commendation signet, I'll exchange it for a small amount of recognition with <faction>.
Please bear in mind that it is better to hand over a stack of ten signets at once; your efforts will receive greater recognition in doing so. We offer a single signet exchange as a service for those who don't have enough for a full stack of ten.
With that being said, I stand ready to assist you if you still wish to hand in a single signet.
