Mechagnomes are a subrace of clockwork-like gnomes affected by the Curse of Flesh.
The first mechagnomes were created by an entity known as the "Grand Architect" within the titan facility of Ulduar. Their job ranks are servants and caretakers. Some these gnomes were turned to flesh by the Curse of Flesh. Some mechagnomes can revert back to normal gnomes but others seem it makes them perfect. Mechagnomes are immortal and cannot die of age but can have a malfunction requiring repair techniques and skills.
