[Whoops, sorry Katsa. He didn't mean to shame her, it was just a perfectly valid question. There was a point in his life where he would resort to less-than-peaceful means to get his way but he's learned since then. Sort of. He nods though, despite the fact it's not entirely what he meant. With the imp unfrozen and directed to the spire to get warm, he gestures for Katsa to follow him again even as he shivers slightly.]

Almost exactly like that, but you want to envision one thing and put all of your power behind it. So...instead of focusing on blankness, focus on the core. It's different than focusing on fighting or something since that's a bunch of moving parts. [He stops then, holding up a hand for her to see. He even goes as far as to close his eyes as he concentrates, envisioning that imaginary circuit board in his chest like he'd explained to Lemina, envisioning the lines and sparks and connections lighting up within and soon very faint glowing lines appear over the lines of his palm.]

This is raw magic. Mine's not as strong yet because I'm still learning how to use it instead of relying on what Lemina gave me, but this is what I'm going to teach you so you can start learning to control fire. Cool, right?
