Butters skateboard

I hoped he was about to throw himself into a getaway car. Instead, he fumbled at his backpack and spun in a comical circle trying to pull something off of it. As he whirled beneath the yellow cone of illumination cast by a streetlight, I saw him take a wide-looking skateboard off where it had been fastened to the pack and slam it to the concrete.
“You’ve got to be kidding me,” I muttered. “A freaking skateboard?”
The suits saw it and surged ahead. I’d seen them move before, and they could pounce like mountain lions. They’d be within a long leap of him in seconds.
Butters threw a glance over his shoulder, his face pale, his eyes huge behind his glasses, and stepped hard onto the skateboard, setting it into motion. He fumbled at a short strap on the front of the board, crouching and taking hold of it with the same intensity as a water-skier about to be launched into motion.
“Go, go, go!” he screamed.
And then a small inferno of orange sparks erupted from the wheels of the skateboard, and the damned thing took off down the empty street at the speed of a motorcycle.
I felt my jaw drop open for a second—and then a bubbling chuckle rolled up out of my chest. Butters, it seemed, had been using more of my old artifice spells, doubtless learned from Bob the Skull. That particular one looked an awful lot like the one I’d put together in my one ill-advised attempt to create a wizardly classic: a flying broomstick. The experiment had damned near killed me, and scared me enough that I abandoned its use until I had a better understanding of the aerodynamics involved, but I’d never even considered applying it to something that wouldn’t necessarily flip me upside down while in motion and carry me into buildings at suicidal speeds. Why had I never applied the same magic to a freaking bicycle?
Or to a skateboard.
Butters didn’t have the kind of power it took to be even a serious sorcerer—but the little guy had knocked together a number of useful magical tools over the past couple of years, also with Bob’s help, and it looked like those exercises had developed into a real gift for creating magical artifices. But how the hell was he powering the damned things? Wizardly tools like that were like toys that needed batteries to work, but Butters didn’t have the strength to power any but the simplest toys. So what was he using as a battery?
Oh. Oh, no.
