As you would correctly assume of an artificer, Lug Nut is a tinkerer--and a rather obsessive one at that. This trait is what landed him his apprenticeship under a master craftsman. Though long before that, a younger Lug Nut could often be found running around said mentor's shop, so it wasn't a surprise to anyone that he eventually started working there in a more official capacity. He spent long hours investigating the innerworkings of each and every contraption he was allowed access to, but one it particular is more relevant to his current journey than the others--a recognizance drone with the form of a metalic falcon. Lug Nut had been sent out to scavenge some scrap from the desert his mentor had a particular need for, only to find himself stumbling into.. the sky.
He had tripped but much to his surprise, instead of hitting the ground, he kept going. The sound of shifting sand had turned into a maelstrom of wind, and before he knew it, he was on the ground again, and well--you know the rest.
