Erebus: Age of Rebirth
Gnomish Eccentric Inventor
Usually completely covered head-to-foot in some kind of golem pilot suit.
The party helped him pick up some spilled mechanical components out on the street and he thanked them. He offered to repair their equipment for free in the future if they found some scattered components for him, which they did.
Turns out Jorpip was a golemancer wizard. But rather than building normal golems like the Luchuirp dwarves, he created a mindless golem that required a pilot!
