The Artificers are draenei who work in construction, engineering, or a creator of artifacts. On Draenor, they were led by Exarch Hataaru, while the ones of the Exodar are led by Grand Artificer Romuul.
Artificers are shapers of crystals and gems. Apprentice Artificer Andren refers to himself as a "warrior-engineer". It is unknown if this applies to the group.
