She looked confused, and Call wanted to kick himself. What did he know about what was okay and what wasn’t? He was the person who kept a mental list of potentially evil behaviors. Was it okay if she didn’t like Tamara? Wasn’t Tamara his best friend, along with Aaron?

Havoc suddenly barked and put his paws up on Celia’s shirt, cutting off the discussion. Celia giggled.

“Callum Hunt!” It was Master Rufus, striding toward them through the crowd. “Keep your chaos wolf silent, please.” He gave Havoc a beady eye and Havoc slid to the ground, looking chastened. “Tamara, Aaron, Call, come with me to your rooms.”

Aaron grinned at Call as they slung their duffels over their shoulders and followed behind Master Rufus through the tunnels. They knew their way, and Call found that he was no longer unnerved by the dripping stalactites and the quiet cool of the caves.

Tamara paused to look into a pool where pale fish darted back and forth. Call thought he saw a crystalline shape scamper over the wall behind her. Was it Warren? Or some other elemental? He frowned, remembering the little lizard.

Finally, they were in front of their old rooms. Master Rufus stepped back to allow Tamara to wave her new copper wristband in front of the door. It unlocked instantly, allowing them into the chambers.

The rooms were just as they’d been when they arrived for their Iron Year. The same chandelier carved with designs of flame, the same half circle of desks, the same duo of plush sofas facing each other, and the same massive fireplace. Symbols picked out in mica and quartz shimmered when the light hit them, and three doors adorned with each of their names led to their bedrooms.

Call let out a long sigh and dropped onto one of the couches.

“There will be dinner in the Refectory in a half hour. Then you’ll put away your things and go to bed early. The first years arrived yesterday. Tomorrow, lessons begin in earnest,” said Master Rufus, with a long look at each one of them. “Some say that the Copper Year of apprenticeship is the most grueling. Do you know why?”

The three of them glanced at one another. Call had no idea what answer Master Rufus was looking for.

Master Rufus nodded at their silence, clearly pleased. “Because now that you know the basics, we’ll be going out on missions. Classes here will be confined to keeping up with your maths and sciences as well as a few new tricks, but the real learning will be out in the field. We’ll begin this week with some experiments.”

Call had no idea what to make of their new curriculum, but the fact that Master Rufus was delighted about it could only be a bad sign. Going out of the stuffy, damp Magisterium classrooms sounded like fun, but Call had been wrong before. During one of their “outside exercises” he’d nearly drowned under a pile of logs, and Jasper of all people had pulled him out.

“Get settled in,” said Master Rufus with his usual regal nod, and swept out of their chambers.

Tamara dragged her suitcase toward her room. “Call, you’d better put on your uniform before dinner — they should have left one for you in your room, like last year. You can’t show up to the Refectory in jeans and a T-shirt that says DOCTOR MONKEY KNOWS WHAT YOU DID.”

“What does that mean, anyway?” Aaron asked.

Call shrugged. “I don’t know. I got it at the Salvation Army store.” He stretched. “Maybe I’ll take a nap.”

“I’m not tired. I’m going to the library,” Aaron said, abandoning his bag and starting for the door.

“You want to find out about the Alkahest,” Call guessed. It was clearly some kind of weapon, but none of them had been able to piece together exactly what it was or what it did. No one seemed to want to answer any questions about it in anything but the vaguest possible terms. And the library at the Rajavis’ house hadn’t held any answers either.
