"Yeah? And what means would that be? I imagine opening a doorway between dimensions would take a lot of power, much less trying to do it in an controlled, directed way."

Oftentimes with magic, at least, the hard part isn't harnessing the energy needed to start a fire, or summon gusts of wind, or anything like that. It's about keeping it under control, stopping the power from exploding out in every direction. But it sounds like Varian has that part figured out, at least.

(Ha, ha ha.)
