She gave Gaotona the stamp she held, letting him inspect it.

“Each of the particular stamps I will use today,” she continued, “will change something small about your past or your innate personality. As you are not Ashravan, the changes will not take. However, you two are similar enough in history that the seals should last for a short time, if I’ve done them well.”

“You mean this is a . . . pattern for the emperor’s soul?” Gaotona asked, looking over the stamp.

“No. Just a Forgery of a small part of it. I’m not even sure if the final product will work. So far as I know, no one has ever tried something exactly like this before. But there are accounts of people Forging someone else’s soul for . . . nefarious purposes. I’m drawing on that knowledge to accomplish this. From what I know, if these seals last for at least a minute on you, they should last far longer on the emperor, as they are attuned to his specific past.”

“A small piece of his soul,” Gaotona said, handing back the seal. “So these tests . . . you will not use these seals in the final product?”

“No, but I’ll take the patterns that work and incorporate them into a greater fabrication. Think of these seals as single characters in a large scroll; once I am done, I’ll be able to put them together and tell a story. The story of a man’s history and personality. Unfortunately, even if the Forgery takes, there will be small differences. I suggest that you begin spreading rumors that the emperor was wounded. Not terribly, mind you, but imply a good knock to the head. That will explain discrepancies.”

“There are already rumors of his death,” Gaotona said, “spread by the Glory Faction.”

“Well, indicate he was wounded instead.”

“But—”

Shai raised the stamp. “Even if I accomplish the impossible—which, mind you, I’ve done only on rare occasions—the Forgery will not have all of the emperor’s memories. It can only contain things I have been able to read about or guess. Ashravan will have had many private conversations that the Forgery will not be able to recall. I can imbue him with a keen ability to fake—I have a particular understanding of that sort of thing—but fakery can only take a person so far. Eventually, someone will realize that he has large holes in his memory. Spread the rumors, Gaotona. You’re going to need them.”

He nodded, then pulled back his sleeve to expose his arm for her to stamp. She raised the stamp, and Gaotona sighed, then squeezed his eyes shut and nodded again.

She pressed it against his skin. As always, when the stamp touched the skin, it felt as if she were pressing it against something rigid—as if his arm had become stone. The stamp sank in slightly. That made for a disconcerting sensation when working on a person. She rotated the stamp, then pulled it back, leaving a red seal on Gaotona’s arm. She took out her pocket watch, observing the ticking hand.

The seal gave off faint wisps of red smoke; that happened only when living things were stamped. The soul fought against the rewriting. The seal didn’t puff away immediately, though. Shai released a held breath. That was a good sign.

She wondered . . . if she were to try something like this on the emperor, would his soul fight against the invasion? Or instead, would it accept the stamp, wishing to have righted what had gone wrong? Much as that window had wanted to be restored to its former beauty. She didn’t know.

Gaotona opened his eyes. “Did it . . . work?”

“It took, for now,” Shai said.

“I don’t feel any different.”

“That is the point. If the emperor could feel the stamp’s effects, he would realize that something was wrong. Now, answer me without thought; speak by instinct only. What is your favorite color?”

“Green,” he said immediately.

“Why?”

“Because . . .” He trailed off, cocking his head. “Because it is.”

“And your brother?”

“I hardly remember him,” Gaotona said with a shrug. “He died when I was very young.”

“It is good he did,” Shai said. “He would have made a terrible emperor, if he had been chosen in—”

Gaotona stood up. “Don’t you dare speak ill of him! I will have you . . .” He stiffened, glancing at Zu, who had reached for his sword in alarm. “I . . . Brother . . . ?”

The seal faded away.

“A minute and five seconds,” Shai said. “That one looks good.”

Gaotona raised a hand to his head. “I can remember having a brother. But . . . I don’t have one, and never have. I can remember idolizing him; I can remember pain when he died. Such pain . . .”

“That will fade,” Shai said. “The impressions will wash away like the remnants of a bad dream. In an hour, you’ll barely be able to recall what it was that upset you.” She scribbled some notes. “I think you reacted too strongly to me insulting your brother’s memory. Ashravan worshipped his brother, but kept his feelings buried deep out of guilt that perhaps his brother would have made a better emperor than he.”

“What? Are you sure?”

“About this?” Shai said. “Yes. I’ll have to revise that stamp a little bit, but I think it is mostly right.”

Gaotona sat back down, regarding her with ancient eyes that seemed to be trying to pierce her, to dig deep inside. “You know a great deal about people.”

“It’s one of the early steps of our training,” Shai said. “Before we’re even allowed to touch soulstone.”

“Such potential . . .” Gaotona whispered.

Shai forced down an immediate burst of annoyance. How dare he look at her like that, as if she were wasting her life? She loved Forgery. The thrill, a life spent getting ahead by her wits. That was what she was. Wasn’t it?

She thought of one specific Essence Mark, locked away with the others. It was one Mark she had never used, yet was at the same time the most precious of the five.

“Let’s try another,” Shai said, ignoring those eyes of Gaotona’s. She couldn’t afford to grow offended. Aunt Sol had always said that pride would be Shai’s greatest danger in life.

“Very well,” Gaotona said, “but I am confused at one thing. From what little you’ve told me of this process, I cannot fathom why these seals even begin to work on me. Don’t you need to know a thing’s history exactly to make a seal work on it?”

“To make them stick, yes,” Shai said. “As I’ve said, it’s about plausibility.”

“But this is completely implausible! I don’t have a brother.”

“Ah. Well, let me see if I can explain,” she said, settling back. “I am rewriting your soul to match that of the emperor—just as I rewrote the history of that window to include new stained glass. In both cases, it works because of familiarity. The window frame knows what a stained glass window should look like. It once had stained glass in it. Even though the new window is not the same as the one it once held, the seal works because the general concept of a stained glass window has been fulfilled.

“You spent a great deal of time around the emperor. Your soul is familiar with his, much as the window frame is familiar with the stained glass. This is why I have to try out the seals on someone like you, and not on myself. When I stamp you, it’s like . . . it’s like I’m presenting to your soul a piece of something it should know. It only works if the piece is very small, but so long as it is—and so long as the soul considers the piece a familiar part of Ashravan, as I’ve indicated—the stamp will take for a brief time before being rejected.”

Gaotona regarded her with bemusement.

“Sounds like superstitious nonsense to you, I assume?” Shai said.

“It is . . . rather mystical,” Gaotona said, spreading his hands before him. “A window frame knowing the ‘concept’ of a stained glass window? A soul understanding the concept of another soul?”

“These things exist beyond us,” Shai said, preparing another seal. “We think about windows, we know about windows; what is and isn’t a window takes on . . . meaning, in the Spiritual Realm. Takes on life, after a fashion. Believe the explanation or do not; I guess it doesn’t matter. The fact is that I can try these seals on you, and if they stick for at least a minute, it’s a very good indication that I’ve hit on something.

“Ideally, I’d try this on the emperor himself, but in his state, he would not be able to answer my questions. I need to not only get these to take, but I need to make them work together—and that will require your explanations of what you are feeling so I can nudge the design in the right directions. Now, your arm again, please?”

“Very well.” Gaotona composed himself, and Shai pressed another seal against his arm. She locked it with a half turn, but as soon as she pulled the stamp away, the seal vanished in a puff of red.

“Blast,” Shai said.

“What happened?” Gaotona said, reaching fingers to his arm. He smeared mundane ink; the seal had vanished so quickly, the ink hadn’t even been incorporated into its workings. “What have you done to me this time?”

“Nothing, it appears,” Shai said, inspecting the head of the stamp for flaws. She found none. “I had that one wrong. Very wrong.”

“What was it?”

“The reason Ashravan agreed to become emperor,” Shai said. “Nights afire. I was certain I had this one.” She shook her head, setting the stamp aside. Ashravan, it appeared, had not stepped up to offer himself as emperor because of a deep-seated desire to prove himself to his family and to escape the distant—but long—shadow of his brother.

“I can tell you why he did it, Forger,” Gaotona said.

She eyed him. This man encouraged Ashravan to step toward the imperial throne, she thought. Ashravan eventually hated him for it. I think.

“All right,” she said. “Why?”

“He wanted to change things,” Gaotona said. “In the empire.”

“He doesn’t speak of this in his journal.”

“Ashravan was a humble man.”

Shai raised an eyebrow. That didn’t match the reports she’d been given.

“Oh, he had a temper,” Gaotona said. “And if you got him arguing, he would sink his teeth in and hold fast to his point. But the man . . . the man he was . . . Deep down, that was a humble man. You will have to understand this about him.”

“I see,” she said. You did it to him too, didn’t you? Shai thought. That look of disappointment, that implication we should be better people than we are. Shai wasn’t the only one who felt that Gaotona regarded her as if he were a displeased grandfather.

That made her want to dismiss the man as irrelevant. Except . . . he had offered himself to her tests. He thought what she did was horrible, so he insisted on taking the punishment himself, instead of sending another.

You’re genuine, aren’t you, old man? Shai thought as Gaotona sat back, eyes distant as he considered the emperor. She found herself displeased.
