“That I can see these spren, and you cannot.” Rock rested a hand on the smaller man’s shoulder. “It is all right, friend. I do not blame you for being blind. Most lowlanders are. It is the air, you see. Makes your brains stop working right.”

Sigzil frowned, but wrote down some notes while absently doing something with his fingers. Keeping track of the seconds? The rock finally popped off the wall, trailing a few final wisps of Stormlight as it hit the ground. “Well over a minute,” Sigzil said. “I counted eighty-seven seconds.” He looked to the rest of them.

“We were supposed to be counting?” Kaladin asked, glancing at Rock, who shrugged.

Sigzil sighed.

“Ninety-one seconds,” Lopen called. “You’re welcome.”

Sigzil sat down on a rock, ignoring a few finger bones peeking out of the moss beside him, and made some notations on his ledger. He scowled.

“Ha!” Rock said, squatting down beside him. “You look like you have eaten bad eggs. What is problem?”

“I don’t know what I’m doing, Rock,” Sigzil said. “My master taught me to ask questions and find precise answers. But how can I be precise? I would need a clock for the timing, but they are too expensive. Even if we had one, I don’t know how to measure Stormlight!”

“With chips,” Kaladin said. “The gemstones are precisely weighed before being encased in glass.”

“And can they all hold the same amount?” Sigzil asked. “We know that uncut gems hold less than cut ones. So is one that was cut better going to hold more? Plus, Stormlight fades from a sphere over time. How many days has it been since that chip was infused, and how much Light has it lost since then? Do they all lose the same amount at the same rate? We know too little. I think perhaps I am wasting your time, sir.”

“It’s not a waste,” Lopen said, joining them. The one-armed Herdazian yawned, sitting down on the rock by Sigzil, forcing the other man over a little. “We just need to be testing other things, eh?”

“Like what?” Kaladin said.

“Well, gancho,” Lopen said. “Can you stick me to the wall?”

“I… I don’t know,” Kaladin said.

“Seems like it would be good to know, eh?” Lopen stood up. “Shall we try?”

Kaladin glanced at Sigzil, who shrugged.

Kaladin drew in more Stormlight. The raging tempest filled him, as if it were battering against his skin, a captive trying to find a way out. He drew the Stormlight into his hand and pressed it against the wall, painting the stones with luminescence.

Taking a deep breath, he picked up Lopen—the slender man was startlingly easy to lift, particularly with a measure of Stormlight still inside Kaladin’s veins. He pressed Lopen against the wall.

When Kaladin dubiously stepped back, the Herdazian remained there, stuck to the stone by his uniform, which bunched up under his armpits.

Lopen grinned. “It worked!”

“This thing could be useful,” Rock said, rubbing at his strangely cut Horneater beard. “Yes, this is what we need to test. You are a soldier, Kaladin. Can you use this in combat?”

Kaladin nodded slowly, a dozen possibilities popping into his head. What if his enemies ran across a pool of Light he had put on the floor? Could he stop a wagon from rolling? Stick his spear to an enemy shield, then yank it from their hands?

“How does it feel, Lopen?” Rock asked. “Does this thing hurt?”

“Nah,” Lopen said, wiggling. “I’m worried my coat will rip, or the buttons will snap. Oh. Oh. Question for you! What did the one-armed Herdazian do to the man who stuck him to the wall?”

Kaladin frowned. “I… I don’t know.”

“Nothing,” Lopen said. “The Herdazian was ’armless.” The slender man burst into laughter.

Sigzil groaned, though Rock laughed. Syl had cocked her head, zipping over to Kaladin. “Was that a joke?” she asked softly.

“Yes,” Kaladin said. “A distinctly bad one.”

“Ah, don’t say that!” Lopen said, still chuckling. “It’s the best one I know—and trust me, I’m an expert on one-armed Herdazian jokes. ‘Lopen,’ my mother always says, ‘you must learn these to laugh before others do. Then you steal the laughter from them, and have it all for yourself.’ She is a very wise woman. I once brought her the head of a chull.”

Kaladin blinked. “You… What?”

“Chull head,” Lopen said. “Very good to eat.”

“You are a strange man, Lopen,” Kaladin said.

“No,” Rock said. “They really are good. The head, he is best part of chull.”

“I will trust you two on that,” Kaladin said. “Marginally.” He reached up, taking Lopen by the arm as the Stormlight holding him in place began to fade. Rock grabbed the man’s waist, and they helped him down.

“All right,” Kaladin said, instinctively checking the sky for the time, though he couldn’t see the sun through the narrow chasm opening above. “Let’s experiment.”

* * *

Tempest stoked within him, Kaladin dashed across the chasm floor. His movement startled a group of frillblooms, which pulled in frantically, like hands closing. Vines trembled on the walls and began to curl upward.

Kaladin’s feet splashed in stagnant water. He leaped over a mound of debris, trailing Stormlight. He was filled with it, pounding with it. That made it easier to use; it wanted to flow. He pushed it into his spear.

Ahead, Lopen, Rock, and Sigzil waited with practice spears. Though Lopen wasn’t very good—the missing arm was a huge disadvantage—Rock made up for it. The large Horneater would not fight Parshendi and would not kill, but had agreed to spar today, in the name of “experimentation.”

He fought very well, and Sigzil was acceptable with the spear. Together on the battlefield, the three bridgemen might once have given Kaladin trouble.

Times changed.

Kaladin tossed his spear sideways at Rock, surprising the Horneater, who had raised his weapon to block. The Stormlight made Kaladin’s spear stick to Rock’s, forming a cross. Rock cursed, trying to turn his spear around to strike, but in doing so smacked himself on the side with Kaladin’s spear.

As Lopen’s spear struck, Kaladin pushed it down easily with one hand, filling the tip with Stormlight. The weapon hit the pile of refuse and stuck to the wood and bones.

Sigzil’s weapon came in, missing Kaladin’s chest by a wide margin as he stepped aside. Kaladin nudged and infused the weapon with the flat of his hand, shoving it into Lopen’s, which he’d just pulled out of the refuse, plastered with moss and bone. The two spears stuck together.

Kaladin slipped between Rock and Sigzil, leaving the three of them in a jumbled mess, off balance and trying to disentangle their weapons. Kaladin smiled grimly, jogging down to the other end of the chasm. He picked up a spear, then turned, dancing from one foot to the other. The Stormlight encouraged him to move. Standing still was practically impossible while holding so much.

Come on, come on, he thought. The three others finally got their weapons apart as the Stormlight ran out. They formed up to face him again.

Kaladin dashed forward. In the dim light of the chasm, the glow of the smoke rising from him was strong enough to cast shadows that leaped and spun. He crashed through pools, the water cold on his unshod feet. He’d removed his boots; he wanted to feel the stone underneath him.
