The Black Prism

The Black Prism is a fantasy novel by American author Brent Weeks. It is the first entry in the five-volume Lightbringer Series, and follows the 'Prism' Gavin Guile, the most powerful person in the world, as he fights against an uprising by a self-proclaimed king.

The book is described by the author as "a story of normal brothers—who happen to be in extraordinary circumstances", and touches on themes of conflict, resentment and love. It was first released in August 2010, and received mostly positive reviews.

Background
The Black Prism is set in a pre-industrial fantasy milieu, albeit more advanced than most, with gunpowder weapons and widespread use of simple machines such as pulleys and gears. The story takes place in The Seven Satrapies, 7 semi-autonomous countries, surrounding a large sea; each satrapy is ruled by a 'satrap'. Satrapies have considerable independence, but are under the loose control of a federalist central government; the Chromeria. The Chromeria is also the seat of education and regulation for the color magic on which the series is based. The ruling council consists of seven "colors", who are essentially representatives from each satrapy, The White, and the Prism. The series is based around the magical principle of chromaturgy, in which light is harnessed to create 'Luxin'. The Prism, apart from being able to use magic of every color, must also be able to "split light", allowing them to use magic more efficiently than normal magicians. A normal magician is called a 'drafter', a drafter may draft until enough Luxin residue builds up in the drafter's eyes to break into the white of the eye, otherwise known as 'breaking the halo'. At this point they go mad and attempt to incorporate luxin into their own bodies. Creatures such as these are referred to as wights, and are terminated with extreme prejudice by the Chromeria, often via the Prism. A Prism represents the god Orholam (a name possibly related to 'hohlraum', a concept in the thermodynamics of radiation, or possibly from the Hebrew 'ohr ha'olam, translated as 'light of the world'), who it is believed bestows magical power onto his chosen. A Prism's abilities, ceremonial authority, status and Chromeria-sponsored protection allow him a great deal of personal agency; however, he has the least official governing power in peacetime, this role falls to the 'white', a non-drafting ruler who decides on most of the Chromeria's political policy. Prisms typically die (or start to lose their colors) after their 7th, 14th, or 21st year of serving.

Only one person a generation is meant to be a 'full-spectrum light-splitter'; however, the two Guile brothers, Gavin and Dazen, demonstrate the same abilities. Gavin, the elder brother, was groomed to be Prism from a young age by Andross Guile, their father and spectrum color. After Dazen burns down the powerful White Oak family house with several women and children inside, he is sought by the Chromeria. The Chromeria's enemies quickly make common cause with him, and the resultant war is brief but bloody. At Sundered Rock, in the Satrapi of Tyrea, Gavin destroys his brother, causing Dazen's general Corvan Danavis to surrender. Tyrea was devastated, with almost all the men killed and its fertile farmland destroyed.

Plot
Sixteen years after the war, the Prism receives a note from a woman claiming to be "Lina," instructing him to meet his now 15-year-old son across the world in Tyrea. He had not known of his son's existence until this point. This child was conceived while Gavin was betrothed to Karris White Oak, a member of his Black-guard, the most elite military force in the world. The White sends Karris to Garriston, Tyrea's capital, to spy on its Satrap's army. She gives Karris a note concerning Gavin's unfaithfulness, to be read after leaving the Chromeria. Gavin is sent somewhere else to keep the two separated, but instead chooses to bring Karris to Garriston himself before she can read the note, using a mode of transportation no one else even believes possible: magically-aided flight across the ocean. This allows them to enter Tyrea in hours, rather than the month or so expected otherwise.

As they draw closer, Karris sees smoke, and directs them to the former town of Rekton, which has been burned to the ground by Tyrean soldiers. They are just in time to save a teenager from being executed, killing several of the Satrap's personal bodyguards in the process. Gavin is then confronted by the irate Satrap himself, who calls himself King Garadul and his Satrapy a true independent nation. The town was burned on his order, as an example, due to their refusal to pay levies.

Tyreans are treated with little respect outside of Tyrea and have no true color on the spectrum. Garriston, the country's only port, is under a rotating occupation from the other Satrapies. King Garadul plans to continue the march of his largely conscripted army to Garriston and seize it, and from there, break the Chromeria's rule over the world.

The child is revealed to be Gavin's son, Kip. Following some debate, heated words, death threats and magic missiles, Kip and the Prism are allowed to leave together. However, the king takes a box from Kip which he claims was stolen from him. The box contains a white dagger given to Kip by his dying mother, who——through curses and abuse——made him promise to kill the man responsible.

Away from all this, Karris reads the note given to her by the White, and is angered by Gavin's betrayal, his lies about it when breaking their engagement, and the White's attempts to manipulate her into forgiving him. Because of this, she ultimately refuses Gavin's offer of assistance the rest of the way to Garriston, opting to explore Rekton while Gavin brings Kip back to the Chromeria. She meets Corvan Danavis, Kip's tutor and a former general of Dazen Guile's army. She is eventually captured by king Garadul, while Corvan continues to Garriston.

While Kip is entered into the Chromeria, shadowed by the Black-guard commander Ironfist, Gavin does a favor for Corvan's daughter Liv in exchange for her teaching Kip, as they are the only Tyreans in the Chromeria. He then enters a prison hidden deep in the Chromeria, containing his brother, whom he has secretly imprisoned in a cell in which nothing but blue luxin can be drafted. It is then revealed that the Prism is in fact Dazen, having stolen his older brother Gavin's identity. When Dazen became Gavin after the war, he chose to break off Gavin's previous betrothal to Karris despite his own feelings, truthfully denying any affairs. The prism interrogates his brother about both Kip and the dagger, which Gavin calls "your death coming." He then meets with his father, Andross Guile, to speak about Tyrea. When he mentions the box Garadul took from Kip, Andross immediately asks if it is "the white luxin," a supposedly mythical substance. His brother Gavin was aware of it as well, and Andross——not knowing Dazen isn't Gavin——assumes he knows what it is. Andross Guile orders his son to defeat Garadul's armies, but at all costs retrieve the dagger.

Kip, the Prism, Ironfist, and Liv leave for Tyrea to defend Garriston from Garadul's armies, sinking several pirates along the way. Corvan reaches Garriston at about this time, and agrees to lead the city's defense. Despite their real-world friendship, the Prism and Corvan must pretend to hate and distrust each other deeply. Liv questions her father about it, but he refuses to tell her the truth. She assumes the Prism is blackmailing him with her life, and silently vows to make him pay.

Liv and Kip run away to free Karris from Garadul's captivity. Ironfist leaves a few hours later, to see to their survival. Liv infiltrates successfully, while Kip is recognized and captured, though not before drafting sub-red for the first time. Karris, meanwhile, is taken to meet Lord Omnichrome, a color wight who heads Garadul's drafters. She recognizes him as her brother Koios, thought-killed by Dazen in overzealous self-defense before the war.

Ironfist helps Karris and Kip escape, and they both go after Garadul directly. Kip sees Lord Omnichrome give Zymun (a red drafter Kip knows from Rekton's burning) his mother's rosewood case, but Kip decides to help Karris. Playing on her disgust with the Prism and Chromeria, Omnichrome persuades Liv to join his cause in return for aiding Kip and Karris. Omnichrome intends for Garadul to die, so Corvan and Dazen try to save him. They are unsuccessful; Kip kills him in a rage before he can be stopped.

Kip, Karris and Corvan retreat to the docks, along with the Prism. Kip saves Ironfist's life before chasing the ship that's already left the dock. As Kip runs across the water, he sees someone stab the Prism from behind with the dagger, and tackles him off the ship. He retrieves the dagger and leaves the assassin for the sharks before escaping with the Prism's ship.

The Prism gives Kip the case, thinking the dagger lost. In it, Kip finds a note from his mother, telling him to kill "the man who raped me, Gavin Guile," and that she loves him. One of the clear diamond-like stones on the dagger's handle is now a sapphire-colored stone. At about this time, the real Gavin escapes from his blue luxin prison after nearly killing himself, only to find himself in an identical green luxin prison. The book ends as Dazen, who is Gavin to the world, discovers that he can no longer draft blue.
