Jasnah was pretty. Lush of figure, tan of skin. Immaculate eyebrows, lips painted a deep red, hair up in a fine braid. Though Jasnah was twice Shallan’s age, her mature beauty was something to be admired, even envied. Why did the woman have to be so perfect?

Jasnah ignored the eyes of the sailors. It wasn’t that she didn’t notice men. Jasnah noticed everything and everyone. She simply didn’t seem to care, one way or another, how men perceived her.

No, that’s not true, Shallan thought as Jasnah walked over. She wouldn’t take the time to do her hair, or put on makeup, if she didn’t care how she was perceived. In that, Jasnah was an enigma. On one hand, she seemed to be a scholar concerned only with her research. On the other hand, she cultivated the poise and dignity of a king’s daughter—and, at times, used it like a bludgeon.

“And here you are,” Jasnah said, walking to Shallan. A spray of water from the side of the ship chose that moment to fly up and sprinkle her. She frowned at the drops of water beading on her silk clothing, then looked back to Shallan and raised her eyebrow. “The ship, you may have noticed, has two very fine cabins that I hired out for us at no small expense.”

“Yes, but they’re inside.”

“As rooms usually are.”

“I’ve spent most of my life inside.”

“So you will spend much more of it, if you wish to be a scholar.”

Shallan bit her lip, waiting for the order to go below. Curiously, it did not come. Jasnah gestured for Captain Tozbek to approach, and he did so, groveling his way over with cap in hand.

“Yes, Brightness?” he asked.

“I should like another of these . . . seats,” Jasnah said, regarding Shallan’s box.

Tozbek quickly had one of his men lash a second box in place. As she waited for the seat to be ready, Jasnah waved for Shallan to hand over her sketches. Jasnah inspected the drawing of the santhid, then looked over the side of the ship. “No wonder the sailors were making such a fuss.”

“Luck, Brightness!” one of the sailors said. “It is a good omen for your trip, don’t you think?”

“I shall take any fortune provided me, Nanhel Eltorv,” she said. “Thank you for the seat.”

The sailor bowed awkwardly before retreating.

“You think they’re superstitious fools,” Shallan said softly, watching the sailor leave.

“From what I have observed,” Jasnah said, “these sailors are men who have found a purpose in life and now take simple pleasure in it.” Jasnah looked at the next drawing. “Many people make far less out of life. Captain Tozbek runs a good crew. You were wise in bringing him to my attention.”

Shallan smiled. “You didn’t answer my question.”

“You didn’t ask a question,” Jasnah said. “These sketches are characteristically skillful, Shallan, but weren’t you supposed to be reading?”

“I . . . had trouble concentrating.”

“So you came up on deck,” Jasnah said, “to sketch pictures of young men working without their shirts on. You expected this to help your concentration?”

Shallan blushed, as Jasnah stopped at one sheet of paper in the stack. Shallan sat patiently—she’d been well trained in that by her father—until Jasnah turned it toward her. The picture of Shadesmar, of course.

“You have respected my command not to peer into this realm again?” Jasnah asked.

“Yes, Brightness. That picture was drawn from a memory of my first . . . lapse.”

Jasnah lowered the page. Shallan thought she saw a hint of something in the woman’s expression. Was Jasnah wondering if she could trust Shallan’s word?

“I assume this is what is bothering you?” Jasnah asked.

“Yes, Brightness.”

“I suppose I should explain it to you, then.”

“Really? You would do this?”

“You needn’t sound so surprised.”

“It seems like powerful information,” Shallan said. “The way you forbade me . . . I assumed that knowledge of this place was secret, or at least not to be trusted to one of my age.”

Jasnah sniffed. “I’ve found that refusing to explain secrets to young people makes them more prone to get themselves into trouble, not less. Your experimentation proves that you’ve already stumbled face-first into all of this—as I once did myself, I’ll have you know. I know through painful experience how dangerous Shadesmar can be. If I leave you in ignorance, I’ll be to blame if you get yourself killed there.”

“So you’d have explained about it if I’d asked earlier in our trip?”

“Probably not,” Jasnah admitted. “I had to see how willing you were to obey me. This time.”

Shallan wilted, and suppressed the urge to point out that back when she’d been a studious and obedient ward, Jasnah hadn’t divulged nearly as many secrets as she did now. “So what is it? That . . . place.”

“It’s not truly a location,” Jasnah said. “Not as we usually think of them. Shadesmar is here, all around us, right now. All things exist there in some form, as all things exist here.”

Shallan frowned. “I don’t—”

Jasnah held up a finger to quiet her. “All things have three components: the soul, the body, and the mind. That place you saw, Shadesmar, is what we call the Cognitive Realm—the place of the mind.

“All around us you see the physical world. You can touch it, see it, hear it. This is how your physical body experiences the world. Well, Shadesmar is the way that your cognitive self—your unconscious self—experiences the world. Through your hidden senses touching that realm, you make intuitive leaps in logic and you form hopes. It is likely through those extra senses that you, Shallan, create art.”

Water splashed on the bow of the ship as it crossed a swell. Shallan wiped a drop of salty water from her cheek, trying to think through what Jasnah had just said. “That made almost no sense whatsoever to me, Brightness.”

“I should hope that it didn’t,” Jasnah said. “I’ve spent six years researching Shadesmar, and I still barely know what to make of it. I shall have to accompany you there several times before you can understand, even a little, the true significance of the place.”

Jasnah grimaced at the thought. Shallan was always surprised to see visible emotion from her. Emotion was something relatable, something human—and Shallan’s mental image of Jasnah Kholin was of someone almost divine. It was, upon reflection, an odd way to regard a determined atheist.

“Listen to me,” Jasnah said. “My own words betray my ignorance. I told you that Shadesmar wasn’t a place, and yet I call it one in my next breath. I speak of visiting it, though it is all around us. We simply don’t have the proper terminology to discuss it. Let me try another tactic.”

Jasnah stood up, and Shallan hastened to follow. They walked along the ship’s rail, feeling the deck sway beneath their feet. Sailors made way for Jasnah with quick bows. They regarded her with as much reverence as they would a king. How did she do it? How could she control her surroundings without seeming to do anything at all?

“Look down into the waters,” Jasnah said as they reached the bow. “What do you see?”

Shallan stopped beside the rail and stared down at the blue waters, foaming as they were broken by the ship’s prow. Here at the bow, she could see a deepness to the swells. An unfathomable expanse that extended not just outward, but downward.

“I see eternity,” Shallan said.

“Spoken like an artist,” Jasnah said. “This ship sails across depths we cannot know. Beneath these waves is a bustling, frantic, unseen world.”

Jasnah leaned forward, gripping the rail with one hand unclothed and the other veiled within the safehand sleeve. She looked outward. Not at the depths, and not at the land distantly peeking over both the northern and southern horizons. She looked toward the east. Toward the storms.

“There is an entire world, Shallan,” Jasnah said, “of which our minds skim but the surface. A world of deep, profound thought. A world created by deep, profound thoughts. When you see Shadesmar, you enter those depths. It is an alien place to us in some ways, but at the same time we formed it. With some help.”

“We did what?”

“What are spren?” Jasnah asked.

The question caught Shallan off guard, but by now she was accustomed to challenging questions from Jasnah. She took time to think and consider her answer.

“Nobody knows what spren are,” Shallan said, “though many philosophers have different opinions on—”

“No,” Jasnah said. “What are they?”

“I . . .” Shallan looked up at a pair of windspren spinning through the air above. They looked like tiny ribbons of light, glowing softly, dancing around one another. “They’re living ideas.”

Jasnah spun on her.

“What?” Shallan said, jumping. “Am I wrong?”

“No,” Jasnah said. “You’re right.” The woman narrowed her eyes. “By my best guess, spren are elements of the Cognitive Realm that have leaked into the physical world. They’re concepts that have gained a fragment of sentience, perhaps because of human intervention.

“Think of a man who gets angry often. Think of how his friends and family might start referring to that anger as a beast, as a thing that possesses him, as something external to him. Humans personify. We speak of the wind as if it has a will of its own.

“Spren are those ideas—the ideas of collective human experience—somehow come alive. Shadesmar is where that first happens, and it is their place. Though we created it, they shaped it. They live there; they rule there, within their own cities.”

“Cities?”

“Yes,” Jasnah said, looking back out over the ocean. She seemed troubled. “Spren are wild in their variety. Some are as clever as humans and create cities. Others are like fish and simply swim in the currents.”

Shallan nodded. Though in truth she was having trouble grasping any of this, she didn’t want Jasnah to stop talking. This was the sort of knowledge that Shallan needed, the kind of thing she craved. “Does this have to do with what you discovered? About the parshmen, the Voidbringers?”

“I haven’t been able to determine that yet. The spren are not always forthcoming. In some cases, they do not know. In others, they do not trust me because of our ancient betrayal.”

Shallan frowned, looking to her teacher. “Betrayal?”

“They tell me of it,” Jasnah said, “but they won’t say what it was. We broke an oath, and in so doing offended them greatly. I think some of them may have died, though how a concept can die, I do not know.” Jasnah turned to Shallan with a solemn expression. “I realize this is overwhelming. You will have to learn this, all of it, if you are to help me. Are you still willing?”
