Warning: this article contains spoilers for theMistbornseries after the bookMistborn: The Final Empire.Brandon Sanderson’s multiversal epic, the Cosmere, is a titanic saga composed of many of his different book series and standalone novels.The Cosmere’s many worlds (and books) are connectedby the long-ago death of the mysterious being Adonalsium, who was betrayed and killed by a coven of conspirators; Adonalsium shattered into sixteen Shards, each a fragment of the greater whole, and yet each with enough power to reshape reality.

While the book seriesMistbornandThe Stormlight Archivesagaare the main focus of the Cosmere, Sanderson has also written numerous short stories that flesh out smaller details of the universe, whether it’s minor characters, worlds without Shards, or just fragmentary ideas that haven’t warranted a full novel yet. In 2016, he releasedArcanum Unbounded: The Cosmere Collected,an anthology of nine short stories set on various worlds of the Cosmere, interspersed with essays and illustrations exploring theextensive magic system of worlds likeMistborn.

9White Sand

Taldain (White Sand)

The desert world of Taldain is home to the powerful Sand Masters, who can manipulate sand in fantastical ways; when a conspiracy results in their being slaughtered,the only survivor is Kenton, the youngest and weakest Sand Master, who must figure out how to keep himself alive when he can’t trust anyone. His only ally is the mysterious Khriss, a woman from Taldain’s strange Darkside, and she clearly has an agenda of her own.

“White Sand” is by no means a bad story, it just doesn’t have the same immediate sense of urgency and importance as the other stories inArcanum Unbounded.Part of that is simply due to the incomplete nature of the text; “White Sand"is actually an older piece of writing than any other piece in the collection, as Sanderson finished the original manuscript of the book in 2001. The series was adapted into a three-volume graphic novel in 2016, which also has a preview inArcanum Unbounded, and that seems much more lively than the original prose.

It was recently announced thatWhite Sandwould get yet another release; in the author’s December 19 blog post detailing his progress on various projects over 2024, he discussed how he’s in the process of revising the text manuscript ofWhite Sand, with an eye towards publishing it in 2026. “Updating 30-year-old-narratives is a big project,” he said in the post with his usual understatement, buthopefully the updatedWhite Sandnovel will sparkle on the page in a way that this excerpt of the original failed to.

8Allomancer Jak And The Pits Of Eltania

Scadrial (Mistborn)

The home of theMistbornseries, Scadrial is a planet that was until recently very hostile to life, but the events at the end of the first novel trilogy reshaped it to the benefit of the people that live there.Mistborn’s Era 2 books show this new Scadrial,now home to a society fairly analogous to the United States in the 1800s, right down to “broadsheets,” the mass-produced newspapers.

Pieces of Jak’s adventures can also be found as interstitial pieces of the Era 2Mistbornbooks

“Allomancer Jak and the Pits of Eternia” is part of a serial story published in those broadsheets,detailing the larger-than-life exploits of the eponymous Allomancer Jak as he adventures across Scadrial, getting into trouble. It’s a hilarious story, partially because Jak is a wonderful parody of our own world’s pulp fiction action heroes like Doc Savage. Pieces of Jak’s adventures can also be found as interstitial pieces of the Era 2Mistbornbooks, which further contrast the bloviating hero against the actual accomplishments of series protagonists Wax and Wayne.

7The Hope Of Elantris

Sel (Elantris)

The world of Sel was a depressing one at the outset of the novelElantris, which showed the eponymous city rotting away, its formerly magical residents now cursed to a wasting, pathetic form of immortality. Thanks to that book’s heroes, though,Elantris and its residents were healed, and their phenomenal powers could again be used to help the world.

Written by Sanderson as a tribute to one of his wife’s students, “The Hope of Elantris” is a short but touching story.

“The Hope of Elantris” follows along with the events of the original novel, butthrough a flashback that focuses on a side character, Matisse, and her fight to save the Elantrian children during the novel’s climactic invasion of the city by the cruel Fjordell. Written by Sanderson as a tribute to one of his wife’s students, “The Hope of Elantris” is a short but touching story and an interesting glimpse at things that happened off-screen during the original book.

6The Eleventh Metal

Another story set on Scadrial, “The Eleventh Metal” is a prequel story, set well before the events of the veryfirstMistbornnovel,The Final Empire. While the original novels showed the character of Kelsier in his prime, a fully realized Mistborn with a plan to take down the cruel Lord Ruler,“The Eleventh Metal” is a glimpse at Kelsier in his youth.

Why The Mistborn Movie Is No Longer Happening

After 14 years of back-and-forth development, the Mistborn film adaptation has come to a halt for now, but the author says to still have hope.

Apprenticing under the gruff Mistborn Gemmel, Kelsier helps his mentor attack a nobleman’s keep. There they find the noble has been experimenting on Kelsier’s fellow skaa in hopes of finding the legendary “eleventh metal,” a supposedly limitless source of power. After killing the nobleman and freeing the imprisoned skaa,Kelsier begins to formulate the plan that would eventually see him crossing blades with the Lord Ruler himself.

“The Eleventh Metal” is a great story, andit’s fantastic to see Kelsier at his most inexperienced. In the mainMistborntrilogy, he’s a seemingly untouchable figure, especially since we see him through the eyes of his own apprentice, Vin. Here, though, he’s a young man only just starting to heal from the horrible trauma that helped him awaken as a Mistborn, and he has yet to develop the signature flamboyance that made him such a charismatic leader of the Skaa Rebellion.

5The Emperor’s Soul

While set on the same planet asElantrisand “The Hope of Elantris,” “The Emperor’s Soul” explores a very different part of that world – the complex and bureaucratic Rose Empire. A Forger named Shai sits in Imperial prison for attempting to steal an artifact known as the Moon Scepter, but instead of being executed for her crimes,the Empire offers her an opportunity: forge the very soul of the Emperor, who has been languishing in a vegetative state from an assassin’s head wound, and she will go free.

“The Emperor’s Soul” is fantastic, and since so much of it specifically revolves around the magic of Forgery, it’s awonderful glimpse at just how deeply fleshed-out Sanderson’s Cosmere magic systems are. It’s also chock-full of Easter eggs and other references to parts of the Cosmere; Shai herself, under a different name, eventually appears in the Era 2Mistbornnovels, where she continues to be an excellent and compelling character.

4Shadows Of Silence In The Forests Of Hell

Threnody

Threnody is one of the most dangerous worlds in the Cosmere, and “Shadows of Silence in the Forests of Hell” is the only story set there so far. The Forests of Hell are a twisted, dark place where shades lurk, waiting to suck the life out of those foolish enough to be out at night. In the story, the innkeeper Silence Montane, secretly a bounty hunter, must go into that very forest at night in hopes of apprehending a bounty that would let her finally pay off her debts, buta betrayal forces Silence to fight the bloodthirsty shades.

“Shadows of Silence” is fascinating, since Threnody has not appeared in any other Cosmere works, as the planet lacks a direct link to any of the other worlds. That means thatthe story is full of tantalizing implications of the horrible history of Threnodyand its people, whose society is clearly teetering on the brink of collapse. Silence is a great protagonist – an accomplished bounty hunter and fighter, and yet those skills only matter to her as a way to keep her inn, and her daughter, safe.

3Sixth Of The Dusk

First Of The Sun

Little is known by the rest of the Cosmere about the world called First of the Sun by its inhabitants, other than how its jungles hide many dangers. Sixth of the Dusk, an Eelakin trapper, visits the island of Patji, where he breeds the magically-impowered birds called Aviar. Once arriving on Patji, he discovers the slaughtered members of a merchant company and the one survivor, a young woman named Vathi, who tells him that the merchants had come doing research with the help of the Ones Above,mysterious travelers from another world.

Every Brandon Sanderson Book, Ranked

Brandon Sanderson is one of the premiere contemporary fantasy authors, known best for the Mistborn series. Here’s how we rank his works.

As with any Cosmere story that shows a world not otherwise explored,“Sixth of the Dusk” is a gripping tale, and all the more thrilling given that the protagonist, Sixth of the Dusk, lacks the magical powers so many other Cosmere protagonists take for granted. His Aviar companions give him limited abilities of foresight, but otherwise, his skills are entirely his own, and he makes for a compelling viewpoint character.

2Edgedancer

Roshar (The Stormlight Archive)

The world of Roshar is as shaped by war as it is by the massive storms that sweep across it, and the people who live there are shaped by them in turn. Roshar is home toThe Stormlight Archive’s narrative, and unlike other stories inArcanum Unbounded, which focus on events away from the plot’s movers and shakers,Edgedanceris a focal piece of the narrative, taking place between book two,Words of Radiance, and book three,Oathbringer.

Edgedancer’s central character is the young girl Lift, who was introduced as a side character inWords of Radianceas she learned how to use her abilities as a Knight Radiant.Edgedancersends Lift to the city of Yeddaw, whereshe tries to save other potential Knights Radiantfrom the man she knows as Darkness, who seeks to slaughter them before they can realize their powers. Along the way, she has another quest of equal import to her – eating all ten kinds of pancakes made in the city in the period known as the Weeping.

Every Radiant Order In The Stormlight Archive & What They Do, Explained

Brandon Sanderson has developed a complex magic system in The Stormlight Archive. Here’s our breakdown of the Knights Radiant orders and their powers.

Lift is a phenomenal character, who seemed unassuming enough in her first appearance inWords of Radiance. Yet it’s clear inEdgedancerand the novels after that she is indeed one of Brandon Sanderson’s favorite characters;this barely teenaged Knight Radiant has a unique perspectiveon the world and people, and it’s that perspective that allows her to so easily change from hilarious to poignant in the same conversation.

1Mistborn: Secret History

Mistborn: Secret Historywas originally released as a standalone ebook in early 2016, but was included in print for the first time inArcanum Unbounded. This novella contains major spoilers forMistbornEra 1, as it reveals thatalthough Kelsier did diein battle against the Lord Ruler inMistborn: The Final Empire, death was only the beginning. Kelsier’s soul was trapped in the Well of Ascension, at least until Vin released the power there; then, traveling south, he worked to help Vin and Elend in their fight against Ruin from the Cognitive Realm where his spirit was trapped.

Secret Historyshowed even more of this mysterious reflection of reality.

While the events of theSecret Historycaught fans by surprise,BrandonSandersonhad been planning this story all along, as evidenced by Kelsier’s return to mortal form inThe Bands of Mourning. While some ofThe Stormlight Archivehas detailed parts of the Cognitive Realm,Secret Historyshowed even more of this mysterious reflection of reality and also confirmed fan theories that Kelsier was too stubborn to actually die.
