In all seriousness though, Vorar's the only one known to exist. Original prototype model, with different chassis designed but never implemented, until Vorar was able to upgrade its own prototype/blank frame to the Crafter designation.
There was also Builder, Soldier, and Caster, which I chose to forgo.
Builder would have even thicker limbs and moderate armor, and extendo-limbs.
Soldier had the strongest armor of any chassis, as well as an extending, rotating sword on one arm.
Mage had terri-weak armor and would slow Vorar down from the added weight of the technomagical equipment, but would allow him to redirect energy to perform evocation magic like Legion the magus did.
The Crafter frame I chose provided heightened dexterity and multi-tool limbs. That's about it. Lucky lucky Altera.
