“I’ll never be like you, Brightness. You have power, authority, wealth. Just look how the sailors respond to you.”

“Am I specifically using said power, authority, or wealth right now?”

“You paid for this trip.”

“Did you not pay for several trips on this ship?” Jasnah asked. “They did not treat you the same as they do me?”

“No. Oh, they are fond of me. But I don’t have your weight, Jasnah.”

“I will assume that did not have implications toward my girth,” Jasnah said with a hint of a smile. “I understand your argument, Shallan. It is, however, dead wrong.”

Shallan turned to her. Jasnah sat upon the deck of the ship as if it were a throne, back straight, head up, commanding. Shallan sat with her legs against her chest, arms around them below the knees. Even the ways they sat were different. She was nothing like this woman.

“There is a secret you must learn, child,” Jasnah said. “A secret that is even more important than those relating to Shadesmar and spren. Power is an illusion of perception.”

Shallan frowned.

“Don’t mistake me,” Jasnah continued. “Some kinds of power are real—power to command armies, power to Soulcast. These come into play far less often than you would think. On an individual basis, in most interactions, this thing we call power—authority—exists only as it is perceived.

“You say I have wealth. This is true, but you have also seen that I do not often use it. You say I have authority as the sister of a king. I do. And yet, the men of this ship would treat me exactly the same way if I were a beggar who had convinced them I was the sister to a king. In that case, my authority is not a real thing. It is mere vapors—an illusion. I can create that illusion for them, as can you.”

“I’m not convinced, Brightness.”

“I know. If you were, you would be doing it already.” Jasnah stood up, brushing off her skirt. “You will tell me if you see that pattern—the one that appeared on the waves—again?”

“Yes, Brightness,” Shallan said, distracted.

“Then take the rest of the day for your art. I need to consider how to best teach you of Shadesmar.” The older woman retreated, nodding at the bows of sailors as she passed and went back down belowdecks.

Shallan rose, then turned and grabbed the railing, one hand to either side of the bowsprit. The ocean spread before her, rippling waves, a scent of cold freshness. Rhythmic crashing as the sloop pushed through the waves.

Jasnah’s words fought in her mind, like skyeels with only one rat between them. Spren with cities? Shadesmar, a realm that was here, but unseen? Shallan, suddenly betrothed to the single most important bachelor in the world?

She left the bow, walking along the side of the ship, freehand trailing on the railing. How did the sailors regard her? They smiled, they waved. They liked her. Yalb, who hung lazily from the rigging nearby, called to her, telling her that in the next port, there was a statue she had to go visit. “It’s this giant foot, young miss. Just a foot! Never finished the blustering statue…”

She smiled to him and continued. Did she want them to look at her as they looked at Jasnah? Always afraid, always worried that they might do something wrong? Was that power?

When I first sailed from Vedenar, she thought, reaching the place where her box had been tied, the captain kept urging me to go home. He saw my mission as a fool’s errand.

Tozbek had always acted as if he were doing her a favor in conveying her after Jasnah. Should she have had to spend that entire time feeling as if she’d imposed upon him and his crew by hiring them? Yes, he had offered a discount to her because of her father’s business with him in the past—but she’d still been employing him.

The way he’d treated her was probably a thing of Thaylen merchants. If a captain could make you feel like you were imposing on him, you’d pay better. She liked the man, but their relationship left something to be desired. Jasnah would never have stood for being treated in such a way.

That santhid still swam alongside. It was like a tiny, mobile island, its back overgrown with seaweed, small crystals jutting up from the shell.

Shallan turned and walked toward the stern, where Captain Tozbek spoke with one of his mates, pointing at a map covered with glyphs. He nodded to her as she approached. “Just a warning, young miss,” he said. “The ports will soon grow less accommodating. We’ll be leaving Longbrow’s Straits, curving around the eastern edge of the continent, toward New Natanan. There’s nothing of worth between here and the Shallow Crypts—and even that’s not much of a sight. I wouldn’t send my own brother ashore there without guards, and he’s killed seventeen men with his bare hands, he has.”

“I understand, Captain,” Shallan said. “And thank you. I’ve revised my earlier decision. I need you to halt the ship and let me inspect the specimen swimming beside us.”

He sighed, reaching up and running his fingers along one of his stiff, spiked eyebrows—much as other men might play with their mustaches. “Brightness, that’s not advisable. Stormfather! If I dropped you in the ocean…”

“Then I would be wet,” Shallan said. “It is a state I’ve experienced one or two times in my life.”

“No, I simply cannot allow it. Like I said, we’ll take you to see some shells in—”

“Cannot allow it?” Shallan interrupted. She regarded him with what she hoped was a look of puzzlement, hoping he didn’t see how tightly she squeezed her hands closed at her sides. Storms, but she hated confrontation. “I wasn’t aware I had made a request you had the power to allow or disallow, Captain. Stop the ship. Lower me down. That is your order.” She tried to say it as forcefully as Jasnah would. The woman could make it seem easier to resist a full highstorm than to disagree with her.

Tozbek worked his mouth for a moment, no sound coming out, as if his body were trying to continue his earlier objection but his mind had been delayed. “It is my ship…” he finally said.

“Nothing will be done to your ship,” Shallan said. “Let’s be quick about it, Captain. I do not wish to overly delay our arrival in port tonight.”

She left him, walking back to her box, heart thumping, hands trembling. She sat down, partially to calm herself.

Tozbek, sounding profoundly annoyed, began calling orders. The sails were lowered, the ship slowed. Shallan breathed out, feeling a fool.

And yet, what Jasnah said worked. The way Shallan acted created something in the eyes of Tozbek. An illusion? Like the spren themselves, perhaps? Fragments of human expectation, given life?

The santhid slowed with them. Shallan rose, nervous, as sailors approached with rope. They reluctantly tied a loop at the bottom she could put her foot in, then explained that she should hold tightly to the rope as she was lowered. They tied a second, smaller rope securely around her waist—the means by which to haul her, wet and humiliated, back onto the deck. An inevitability, in their eyes.

She took off her shoes, then climbed up over the railing as instructed. Had it been this windy before? She had a moment of vertigo, standing there with socked toes gripping a tiny rim, dress fluttering in the coursing winds. A windspren zipped up to her, then formed into the shape of a face with clouds behind it. Storms, the thing had better not interfere. Was it human imagination that had given windspren their mischievous spark?
