“Of course we are,” Waxillium said. “But away from the coach.”

Wax held the vibrating cube in his hand. It did respond to his metal burning, but didn’t seem to do anything else.

They’d stopped near a stand of towering walnut trees, and Wayne was filling his pockets while Marasi watched Wax experiment from a safe distance. MeLaan watered the horses at a stream down the way. Nearby, a field of carrots grew with green sprouts, completely uncultivated. The air smelled fresh, of life untouched.

He held up the buzzing cube and let his metals die off. The cube stopped vibrating. He burned them again, and it responded—starting slowly, but picking up after about a second or two. But what did it do? Why didn’t it blank his Allomancy as it had on the train?

Maybe it doesn’t work on the person activating it, he thought. That would make some kind of sense, though he couldn’t fathom how it could tell. “Hey, Wayne,” he said.

“Yeah, mate?”

“Catch.”

Wax tossed the cube to him. Wayne caught it, then jumped as his belt—which held his metal vials and any coins on his person—ripped free from its breakaway straps and sprang away from him. He turned, watching it flop to the ground a good twenty feet down the hill, and when he approached it, it scooted away.

Wax ran toward him, and as he did, the shotgun in his leg holster pressed backward, as if being Pushed. The effect wore off a few seconds later, and by the time he reached Wayne, the cube had stopped buzzing.

Wayne held it up. “What was that?”

Wax plucked the device from his fingers as Marasi rushed over to join them. “It doesn’t steal Allomancy, Wayne. It never did.”

“But—”

“It takes the metal one is burning,” Wax said, “and somehow… extends it. You saw. It Pushed your metal away, as if a Coinshot were there near you. The cube used Allomancy.”

The three of them stood stunned, looking at the little device.

“We need to try it again,” Wax said. “Wayne, hold this and burn your bendalloy. Marasi, go stand over there. Wayne, once you’re ready, throw the cube to her.”

They did as directed. Wax stood back. When Wayne ignited his metals, he suddenly became a blur inside his speed bubble. The cube zipped out an eyeblink later and soared through the air toward Marasi, deflected somewhat but still moving in the right direction.

It engaged just before reaching her, and she became a blur, zipping over to pick up the cube, then zipping back. It took a count of ten before the cube stopped working, dropping her into ordinary time.

“Did you see that?” Marasi said, awed, holding the cube. “It created a speed bubble for me. It fed off Wayne’s Allomancy, and replicated it!”

“It’s what we’ve been lookin’ for, then?” Wayne asked, joining them, having dropped his own bubble.

“Not quite,” Wax replied, taking the cube and holding it up. “But it’s certainly encouraging. It looks like you have to be an Allomancer to use this—it doesn’t grant new powers, but it does extend the ones you have. It’s like… like an Allomantic grenade.”
