Literature: The Mistborn Adventures aka: The Alloyof Law
"When I found my way out to the Roughs, when I started bringing in the warranted, I started to... Well, I thought I'd found a place where I was needed. I thought I'd found a way to do something that nobody else would do. And yet, it appears that all along, the place I left behind might have needed me even more. I'd never noticed."
—Waxillium "Wax" Ladrian
The Mistborn Adventures is a Sequel Series to the first of the Mistborn trilogies by Brandon Sanderson, set roughly 300 years after the events of Hero of Ages. It features Waxillium Ladrian, a noble that became a lawman in the Wild West-esque Roughs returning to his home in the city of Elendel to try and settle down. His attempts at the quiet life are quickly foiled, however, by the return of his old friend Wayne, his own internal desire to do the right thing, and the appearance of a mysterious group of thieves called "The Vanishers". Now, Wax, Wayne and newcomer Marasi Colms must team up to solve crimes and save the city. However, the Vanishers are only just the beginning of a much deeper conspiracy...Originally conceived while Sanderson was taking a break from working on the last volumes of The Wheel of Time as a writing exercise, the story quickly grew beyond its planned scope, and was deemed suitable for publishing as a fully-fledged novel. Brandon Sanderson plans to write three or four books in this series before the release of the second Mistborn trilogy (planned to be set in a modern day universe with an Allomantic SWAT Team). There are currently two officially named books:
Anti-Magic: Aluminum (and some alloys thereof) is allomantically inert, and can't be Pushed or Pulled allomantically like other metals. In addition, wearing an aluminum foil hat (or just one lined with aluminum) protects against emotional Allomancy.
Axe Crazy: Bloody Tan, the villain of the prologue, is a serial killer. Also, several other criminals from Wax and Wayne's Backstory, some of them quite nasty, are mentioned in passing.
The Cameo: Hoid, Sanderson's Legacy Character who appears in every other book in the overarching multiverse of his setting, briefly appears at the wedding party, though not directly referenced by name, instead being mentioned as a shabby-looking fellow in black who might have been a beggar. The wedding in question is of two 17thShard (a fan site) worldhoppers, according to Sanderson.
Ranette the gunsmith is mentioned early in the book; it's no surprise when she shows up nearer the end.
As part of a bit of world-building, Marsh aka Ironeyes, showing up right at the end.
Chekhov's Skill: Marasi is convinced her Allomantic power is useless. Being able to slow down time by a significant factor for a large area allows the Wax and Marasi to stall for time as Wayne goes to fetch the military to apprehend the indestructible Miles.
Deus ex Machina: Played with. It certainly looks like a literal version of this when Harmony actually starts helping Wax out in the finale...then the epilogue confirms that Harmony is Sazed, and definitely more of an active agent than he appears.
Wayne says that Wax was lying about not bringing a gun. Wax replies that he didn't bring a gun and draws a second one.
After Steris asks that people stop talking about shooting people and hitting them with bricks, Marasi brings up throwing knives at them.
Face-Heel Turn: Miles, though his time as a Face was before the book started.
Functional Magic: Same magic system from the original trilogy, though Feruchemy has been broken up into one-power per person, and Twinborn are people with one Allomantic and one Feruchemic power. Notable in that Twinborn are repeatedly said to be extremely rare, while Wax and Wayne are both Twinborn...
Game Breaker: invoked Miles is a double-gold Twinborn, letting him get more health than he started with out of a metalmind. Although he still ages, he's functionally immortal. All the Compounders (Twinborn with matching metals) are overpowered, but a double-gold is a particularly dangerous variety.
Genre Savvy: One of the many reasons Miles is dangerous.
Grim Reaper: Former Steel Inquisitor Marsh (now called "Ironeyes") is believed to be this by most people.
Good Thing You Can Heal: Wayne takes a lot more punishment than Wax does. Miles takes more than both combined. Wayne actually lampshades this at one point, and mentions that people tend to shoot Wayne when they're mad at him, since they know he can heal.
Wayne: It was like saying it was fine to steal a man's beer because he can always order a new one.
Of course, considering that in a world of firearms Wayne's favorite tactic is to use his time-speeding ability to turn the battlefield into a series of one on one duels, cane vs guns... it's not surprising that he'd cop a clobbering.
Wayne is able to rapidly heal from injuries as long as he has "health" stored in his gold metalminds (metal used for storing Feruchemy). Since the exchange is one-to-one, the net effect is still equivalent to normal healing — each "unit" of health stored that can be tapped to speed up healing required him to worsen his health by an equivalent amount at some point in the past. Attempting to store up health and then using it to heal up while injured just means that the periods of lowered health will cancel out the periods of heightened health.
Miles is a twinborn whose Allomantic and Feruchemic metals are the same — gold. This allows his powers to interact in a fashion called Compounding, where the energy stored in a metalmind can be accessed by Allomancy, and which releases considerably more Feruchemical energy when burned, allowing the Compounder to bypass the sum-zero limitation of normal Feruchemy, as long as there is a supply of the metal available for burning. In this case, it allows the regeneration of all but the most fatal wounds in seconds and renders the user functionally immortal.
Henpecked Husband: At first it looks like Wax is doomed to become one of these; his fiancee Steris at first appears to be a joyless, humorless matron who hands him a fifty-page prenuptial agreement. Averted, however, in that it later becomes apparent that Steris is just socially awkward and a meticulous planner, who fully intends to respect Wax's privacy and personal freedom. He marries her after all, probably in part so she can manage his business empire while he chases down criminals.
Hold Your Hippogriffs: As with the original Mistborn trilogy, there are a lot of metal-based figures of speech in the language.
The events of the original trilogy have taken on mythological and religious significance to the later generations. The most humorous of these changes is the ancient High Speech; when an example of it is given, it's quickly recognizable to readers as the silly-sounding thieves' cant used by a few characters in the original trilogy.
There are no more full Mistborn, and Wax considers them at least half-mythical. Hemalurgy, the art of transferring Allomantic powers to other people by killing the donor with a metal spike and embedding it in the body of the recipient, is also forgotten according to the appendix.
Lighter and Softer: The Alloy of Law is much less serious then the original trilogy and the setting is much less grim.
Magic Pants: Miles sets off dynamite in his hand to escape a net. His shirt is destroyed, but his pants survive.
Mad Scientist: Although Ranette is more a Mad Engineer, she does live like a hermit, and has an obsession of building better guns and ammunition.
Medieval Stasis: Averted. Technology has progressed in many many fields since the events of the first trilogy. Also, the way people talk about philosophy and criminology is downright modern.
Named Weapon: Vindication, sufficiently awesome to deserve its namesake.
Nobility Marries Money: The protagonist Wax who is the current Lord of an old but currently broke house, arranges a marriage contract with a woman from a young and well off house.
Nouveau Riche: Steris' family, and the reason for her betrothal to Waxilium. One has the money, but not the name. The other is old, respected and penniless.
Obfuscating Stupidity: Wax's uncle, to a degree that makes him an instant Chessmaster. Incompetent noblemen gambling and carousing their houses into financial ruin is a plot point that shows up often enough that even most readers wouldn't bother to question it.
Rescue Romance: Discussed. Steris points out that she and Wax can accelerate the timeline for their wedding and avoid the normal scandal in high society specifically because everyone will assume this trope is in effect.
Replacement Love Interest: Both subverted and defied. Marasi is extremely similar to Lessie to the point where Wayne tries to play matchmaker with her and Wax, but her similarity to Lessie is the reason why Wax rejects her: He's no longer the same person he was at the beginning of the book.
Shown Their Work: Marasi shows a fair knowledge of criminology and sociology, and makes mention of the real-world "broken windows" theory. Also, aluminum, despite its ubiquity, really was more valuable than gold in the late 1800s before its refining process was perfected.
Talking Is a Free Action: Justified by Wayne's time-bubbles, which speed up time in a small bubble. When the duo need a moment to plan during a big fight, they duck inside a bubble and hold long conversations.
The Cavalry: Wayne arrives at the head of a small army of constables to take down Miles in the finale, having been sent to fetch them at the start of the final confrontation, before Marasi started slowing down time.
Too Awesome to Use: When Wax has a store of rounds designed for use against specific types of Allomancers, he finds he's reluctant to use them except for their intended purpose, even when it means shooting a lot less often than he should be.
Earlier on, part of the reason why Wax and Wayne are able to kill so many of the Vanishers when Steris is kidnapped is that the Vanishers didn't already have their aluminium bullets ready as they were ordered, being reluctant to waste the expensive metal on normal targets.
Unspoken Plan Guarantee: Played with: Wax has two plans to deal with Miles. We aren't told much of either in advance, but Plan A fails while plan B works.
Unusual Euphemism: Rust and Ruin! Might also be considered a form of Oh My Gods!, since Ruin actually is a (mostly dead) god in-universe (rust isn't divine at all, but makes sense as a curse considering the importance of metal).
Marasi's Allomantic power is, at first glance, nothing special, and she fails to see the point of it. However, being able to significantly slow local time in a large area lets her and Wax buy the time needed for Wayne to fetch reinforcements to apprehend the indestructible Miles.
Aluminium and duralumin Mistings are referred to as "Aluminum/Duralumin Gnats" due to their powers having no practical uses at all. Both their metals have no effect except on other metals that the user is burning; aluminum instantly depletes a Mistborn's reserves of all metals, and duralumin works as a sort of "super-flare" for any other metals being burned at the time, depleting it all in an instant for a single massive effect. Both of these are only useful to full Mistborn, however, as they are the only people who can burn more than one metal- and since there are no Mistborn anymore, those people unlucky enough to be aluminum or duralumin Mistings essentially have no powers at all.
