Looking at the Camera feed, Barnon has some kind of... laser, he produces from part of the machine that is strapped to his back, instead of a Unicorn horn on his head. But it's not magic. He said it was pure Energy? He slowly carves out the stone around the Borutine, before taking the large chunks, and floating them towards his Ship-Post. Watching him work as if nothing weighs anything is confusing, but I think I'm starting to get it.
