Wirz Cogizmo is an up-and-coming entrepreneur that suffered an intense overdose of Kaja'mite dust during a cave collapse on Kezan, which itself happened during the evacuation of the island following Deathwing's attack.

He escaped within an inch of his life by hiding in the trunk of the KTC CEO's hot-rod (yes, the one the player characters drive during the starting zone). It seemed the sudden influx of Kaja'mite, which could have killed him, was enough to spur him to safety. All the while, though, all he could seem to think about was the concept of free energy. Not necessarily 'clean' for the sake of cleanliness, but that was a healthy byproduct of his research.

We can see him here working on one of his little portable project boxes.
