And the Adventure Continues: Shai ends the novella leaving the royal city to find Hoid, the Imperial Fool, and get payback for his betrayal.
Better Than New: The maxim of a good forgery: improve slightly on the original, and people would often accept the fake because it was superior
Bilingual Bonus: When Shai steals her forgery of the painting from Frava she leaves a Reo rune in it's place. Readers of Elantris will recognize this rune as meaning Punishment or Retribution.
Blackmail: Frava assumes that Shai will use her knowledge of the Emperor's new state in this way once she finishes her work. However, as Gaotona accurately assumes, this is untrue, and Shai just wants to finish her job under the assumption of Doing It for the Art.
Blood Magic: To prevent her from escaping a sample of Shai's blood is taken daily by a Bloodsealer. This blood is used in a special stamp on her door which will let the Bloodsealer know if she leaves the room and can then be used to track her.
Burn Baby Burn: The novella closes on Gaotona doing this to Shai's real notes on the linchpin soulstamp for the emperor after reading them to cover her tracks.
Compliment Backfire: Shai tells Gaotona that she is impressed that he thinks like a Forger, and, despite his annoyance, that it was meant as a compliment.
Contrived Coincidence: What are the chances that the world's greatest forger is being held in the prison just as the world's most difficult forgery is needed? Subverted; Probably quite high when Hoid is the one who got her arrested.
Impossible Task: Shai claims to have completed several on "rare occasions", and also considers Forging a complete soul in three months to be this.
Insistent Terminology: Frava despises Shai for being a Forger, but the Heritage Faction uses Forgers to turn ordinary pots into replicas of ancient ones. However, she justifies this by calling their Forgers "Rememberers", which Shai notes is basically the exact same thing.
Insult Backfire: When Gaotona calls Shai (to Zu) "a master trickster, liar, and thief" who could turn guards to clay in her hands, Shai thanks him, even though it was not a compliment.
Kansas City Shuffle: Shai made two fakes of the painting she stole from Frava, one slightly less exact than the other, and burned the original, so that Frava would find the worse fake and keep the better one without knowing what was done.
Kill It with Fire: Shai does this to a painting when she originally came to the Rose Palace. The artist, blind and unable to make any more such paintings, asked her to.
Locked in a Room: Shai herself is literally locked in one, Gaotona has to come visit her frequently for other reasons. They grow to appreciate each other over the course of the story.
My God, What Have I Done?: Gaotona has this reaction when Shai reveals that Ashravan resented him for persuading him to become Emperor in the first place.
Necromancer: The other part of a bloodsealer's abilities. They can track you with their blood- and sick the reanimated dead on you. Shai is threatened not only with being attacked this way if she tries to run, but with being turned into a skeleton warrior herself if she is killed.
Oh My Gods!: "Nights (afire)" for Shai; "Days (alight/afire", and "Mother of lights" for the Rose Palace natives.
Out-Gambitted: Shai begins the story out-played by the Imperial Fool, who stole the Moon Scepter and sold her out before running off.
Reality Warper: All Forgers, but only within tight limits. Their stamps are temporary, with duration depending on how plausible the change from the original history of the object is. For instance, it's easy to make gold into lead by rewriting the history of the object so it had been mixed with lead once, but turning lead into gold is essentially impossible because there's pretty much no way something meant to be lead would have been made out of gold instead.
Squishy Wizard: Shai when she's not being Shaizan; her magic is based more around scholarship and skill than fighting strength, after all. The Bloodsealer goes down pretty easy as well once his "pets" have been dealt with.
Tear Jerker: In-Universe, Gaotona's reaction to finding out the sheer masterpiece of the alterations in Shai's Forging of the emperor's soul.
You Have 48 Hours: Shai has to complete the soul of the Emperor in 99 days, including the day of her employment. She considers this an Impossible Task, since she assumes it will take two years to get the necessary knowledge.
You Have Outlived Your Usefulness: Shai is well aware that she will be killed once she has completed her task for the emperor, despite the promises of Frava. Therefore, part of her plan is to work to avoid this happening. She succeeds.
She Knows Too Much: The other reason she will likely be killed, having blackmail against the Heritage Faction.
