“Call,” Aaron said. “I mean, my counterweight is Call. Not everyone’s is Call. But the counterweight for chaos is a person. Just … not always Call.”

“Eloquent as always,” said Rufus. “And is there a problem with a counterweight?”

“It’s hard to find one sometimes?” Aaron was clearly guessing, although Call thought he had to be right. Finding fire seemed like it would be hard. Maybe adult mages all carried lighters.

“It limits your power,” Tamara said. Master Rufus nodded in her direction, indicating that she’d given the superior answer.

“Limiting your power is part of how it keeps you safe,” he said. “Now, what is the opposite of a counterweight?”

Tamara answered that, too, showing off. “What we did with the sand last year.”

Call wanted to make a face at her, but he was pretty sure he’d get caught. That was the problem with three-person classrooms.

Master Rufus nodded. “Sympathetic acceleration, we call it. Very dangerous because it draws you deeper into the element. It gives you power, but the price can be very high.”

Call hoped this wasn’t the beginning of a lecture about how he had been a problem back then and was still a problem now.

But Master Rufus moved on. “What I’d like you all to do is to practice using your counterweights. First, gather up something to represent each of the elements. Aaron, this is going to be especially challenging for you, as you have chosen Call for your counterweight.”

“Hey!” Call said.

“I meant only that working with a human counterweight is challenging. Now, go, find your counterweights.”

Call walked around the edge of the grotto, finding a rock. Air was all around him, so he figured he had that covered. Fire and water were harder, but he used magic to turn some of the water from the silty cave pool into an orb he kept floating near his head. Then he took a vine and resolved to light it on fire with magic when the time came.

He went back to where the others were standing. Of course, they’d completed the exercise before he had.

“Very good,” said Master Rufus. “Let’s start with air magic. I am going to use air magic to send each one of you up into the air — but keep hold of your counterweight. It’s going to be your only contact with earth magic. Come down once you feel you need to use the counterweight.”

One by one, they were sent up into the air. Call could feel it whistling around him, the exhilarating lure of flying making him giddy. Flying was his favorite part of magic. In the air, his leg never bothered him. He began to use air magic, forming patterns of color, making clouds and then flying through them. The more magic he expended, the more he understood how someone could be Devoured. It seemed to him that becoming part of the air wouldn’t take much. He could relax into it and be blown along like an errant leaf. All his worries and fears would be blown away, too.

All he had to do was drop his bit of rock.

“Call.” Master Rufus was looking up at him. “The exercise is over.”

Call twisted around to see that Tamara and Aaron were already on the ground. He reached down to his stone and let the weight of its connection to earth fill him, lowering him slowly until he was standing again, his leg aching as always.

Rufus gave Call a measured look. “Well done, everyone,” he said. “Now, Aaron, we’re going to try an exercise involving chaos. Something small.”

Aaron nodded, looking nervous.

“You shouldn’t be worried,” said Rufus, indicating that they should clear a space in the center of the room. “If I understand correctly, you defeated many Chaos-ridden when you fought Master Joseph last year.”
