Jacs spent most of his time growing up learning about the inner workings of machines and how to keep them running, and despite his more martial heritage, he has found a little nook within a cold and wind-swept barn on Nar Kanji to operate as a mechanic. With no true preference as to what he works on, Jacs is known to enjoy tinkering on all manner of vessels and vehicles.
Repairs? Jacs often has his kit slung over a shoulder, cloak snagged on some buckle or other. Need a repair? Sure. He'll oblige.
Not exactly the most hospitable of planets, Jacs tends to swaddle himself in his cloak and curl up amidst his equipment when seeking a few moments of sleep, as and when he can. But it's away from the neon, away from the hustle of the city, it's Jacs' spot. The oft windswept and snowswept barn in which he hunks down is where Jacs operates his little business from, and it is here that he can modify (and repair) both freighters and starfighters. Sure it's cold and somewhat unforgiving, but it's home.
