NATO anti-terror agent Eve Baird meets Flynn Carsen during a mission in Berlin, and, on her return to the United States, is invited to join the Library as the Guardian, tasked with protecting the Librarians. Despite Flynn's resistance, she works with him to investigate the murders of several former Librarian candidates, and they rescue three who are still alive: mathematician Cassandra Cillian, art expert Jacob Stone, and thief Ezekiel Jones. With their help, Flynn and Eve link the murders to the Library's ancient enemy, the Serpent Brotherhood, and prevent them from stealing the crown of King Arthur from a stonehenge circle in northern England. When they return to the Library, however, Cassandra betrays them and leads the Brotherhood to the Library. When Flynn intervenes, a Brotherhood lieutenant, Lamia (Lesley-Ann Brandt), stabs him with Arthur's sword, Excalibur. As the Librarians escape, Judson and Charlene cast a spell to seal off the alternate dimension where the Library resides.
2	2	"And the Sword in the Stone"	Dean Devlin	John Rogers	December 7, 2014 (2014-12-07)	5.35[2]
As the Library begins to seal itself off, Eve, Jake, Ezekiel, and a mortally-wounded Flynn exit through a door to a remote forest in Oregon, where they meet Judson's old friend Jenkins, who runs a branch of the Library in Portland. As his wounds cannot be treated, Flynn commits himself to spending his last day preparing the others to take over from him. They track Lamia and the Brotherhood to a Roman crypt beneath Buckingham Palace, where the latter plan to perform a ritual that will flood the world with magic. With Cassandra's help, the group regains control of both the crown and Excalibur, though not before Lamia manages to complete the ritual. Using what little magic Excalibur has left, Cassandra heals Flynn instead of using it to eliminate her tumor. Eve begins to develop feelings for him, and they share a kiss before he leaves the group to search for a way to restore the Library.
3	3	"And the Horns of a Dilemma"	Marc Roskin	Jeremy Bernstein	December 14, 2014 (2014-12-14)	3.37[3]
Eve works to train the Librarians as soldiers, but is continuously frustrated by their lack of experience. Against her wishes, they head to Boston to investigate the disappearance of several interns at a prominent agribusiness firm. Eve becomes suspicious after meeting with the CEO, Karen Willis (Tricia Helfer), and breaks into the server room, where she finds a collection of artifacts. Stone deduces that the firm is using the artifacts to create a labyrinth, complete with a captive minotaur (Tyler Mane). Willis reveals that the company is in fact the last remnants of the Minoan monarchy, having survived for centuries on the power of the labyrinth. Ezekiel and Cassandra are able to deactivate the artifact room, allowing the minotaur to take its revenge on Willis. Eve concludes that the best way to manage the Librarians is to let them gain experience on their own terms.

The Librarians learn that Santa Claus (Bruce Campbell) has disappeared hours before Christmas. Jenkins explains that Santa is an "immortal avatar" who spends the year collecting goodwill; if he does not return it by the stroke of midnight, the world will fall into chaos. The team heads to London, where they find that the Serpent Brotherhood has poisoned him with mistletoe, causing him to become Sinterklaas and then Odin. They attempt to fly him out to the aurora borealis in Alaska so that he can finish his work, but are ambushed by Lamia and Dulaque (Matt Frewer), the leader of the Brotherhood. Dulaque throws himself out of the plane, but Jenkins admits that he will survive. Santa explains that Eve, having been born at the exact hour of Christmas Eve (hence her name), is the only one who can restore hope to the world, and despite her dislike for Christmas, she agrees to do so.

Flynn returns with troubling news: the Eastern dragons are threatening war unless a missing treasure is returned. The Librarians travel to a dragon lair under Vatican City, where they discover that the Brotherhood is using the dispute to persuade an important meeting of the supernatural community to dismantle the Library. The treasure, which turns out to be the Apple of Discord, corrupts both Jake and Cassandra before Flynn takes it back to the Library, where he (with the help of Ezekiel and Jenkins) convinces the delegates to maintain the Library as a check on the abuse of magic. Eve accepts Flynn's offer to make her a full Guardian, but disagrees with his plan to stay in Portland. Realizing that he still has to find the Library, Flynn departs once again.

Near a small town in Washington, a truck is thrown off a bridge by a giant hand. The Librarians investigate and discover a large statue under the bridge, which they identify as a troll. They also discover that many of the town's residents are being turned into characters from popular fairy tales. It turns out that the town librarian (René Auberjonois) has been using an enchanted story book to become immortal by reading it to a young girl and draining her spirit, bringing the stories to life in the process. The Librarians themselves fall victim, with Cassandra becoming Prince Charming, Eve a princess, Jacob the Huntsman, and Ezekiel turning into Jack. Ezekiel persuades the girl to wish for a happy ending, imprisoning the librarian inside the book and undoing his magic. It is subsequently revealed that Cassandra, having briefly gained the ability to use sorcery, has retained some of her powers.
7	7	"And the Rule of Three"	Marc Roskin	Paul Guyot & Kate Rorick	January 11, 2015 (2015-01-11)	3.44[7]
The clipping book sends the Librarians to a Chicago-area science fair, where strange incidents linked to magic have occurred. While the others, posing as judges, investigate the fair, Eve confronts the host (Alicia Witt), who Jenkins exposes as the sorceress Morgan le Fay. Morgan explains that she has given the students an app that allows them to place curses on their competitors, forming an improvised coven that she can draw on to replenish her powers. Eve manages to temporarily strip her of her immortality using the app, but is forced to let her escape when the building magical backlash threatens to cause a major disaster. Using the expertise of a sympathetic student (Bex Taylor-Klaus), the Librarians are able to craft a Faraday cage to dispel the backlash. Before vanishing, Morgan taunts Eve with the knowledge that an unknown calamity will soon fall upon the Library. She leaves Eve with a Latin warning for Jenkins (whom she calls Galeas): "Don't fear the villain, fear the hero".

While inspecting ley lines in Slovakia for disturbances, the Librarians run into a teenage girl named Katie (Lea Zawada), who begs them to save her friends from a nearby house. Eve takes Jake and Ezekiel to investigate, leaving Cassandra to watch Katie. Jenkins suggests that the "house" may be one of several magical shelters that occasionally appear to either help or harm travelers. Inside the house (which Stone identifies as 19th-century American frontier), the three are attacked by a shadowy entity and imprisoned inside a dollhouse. Cassandra discovers that the entity is trying to protect them from Katie; after her family discovered the house centuries ago, she banished them and took control of the house, using it to prey on strangers. Cassandra overpowers and turns Katie to dust, releasing her friends and restoring the house's original caretaker spirit, who wishes them well as they return home.
9	9	"And the City of Light"	Tawnia McKiernan	John Rogers & Jeremy Bernstein	January 18, 2015 (2015-01-18)	3.27[8]
The Librarians visit a small town in upstate New York where a UFO researcher has disappeared. They eventually discover the town's secret: An experimental wireless grid built by Nikola Tesla in 1915 trapped the town's original inhabitants in a pocket dimension, from which they can influence the modern world only by temporarily taking over the bodies of others, including the missing researcher. The town leader, Mabel Collins (Haley Webb), who bonds with Stone over their shared experiences of isolation, reveals that Tesla designed a capacitor to reverse the experiment, and the Librarians help her restart it after Eve becomes stuck in the dimension as well. At the last second, they abort the procedure to prevent a Tunguska-level explosion, releasing Eve but removing Mabel's immortality, causing her to age and die. The other townspeople remain trapped, and Jenkins estimates that it will take another century before they can be found again, which he and Eve list as a priority for future Librarians.
10	10	"And the Loom of Fate"	Jonathan Frakes	John Rogers	January 18, 2015 (2015-01-18)	3.03[8]
Flynn returns to the Library, having gathered an assortment of artifacts to restore the Library. However, Dulaque interferes and acquires the Loom of Fate, which he uses to rewrite history and prevent the downfall of Camelot. This sends Eve into an alternate timeline where Flynn did not become a Librarian. Together, the two make their way through other worlds created by the Loom, where they encounter alternate versions of Cassandra, Ezekiel, and Jake, all of whom have replaced Flynn in their timelines. Cassandra, having fully developed her powers of sorcery, sends Eve and Flynn to the River of Time, where they encounter Jenkins and a younger Dulaque (Jerry O'Connell), who reveals that he is Lancelot and Jenkins Galahad. While Eve and Jenkins fight Lancelot, Flynn uses the Loom to fix history and send the three back to the Library in time to save Eve from a mortal wound. As a reward for their service, Jenkins entrusts the Librarians with their own clipping books. While the others go on their first unsupervised mission, Flynn invites Baird on a "first date", taking her through a portal to an unknown place.

Since Lancelot's defeat, the Librarians have gone their separate ways. Several months later, at a museum exhibition in New York City, they reunite after retrieving different artifacts on behalf of a mysterious client. The client turns out to be Moriarty, who has gathered the artifacts for his master, the wizard Prospero, who intends to undo the ending of The Tempest (where he voluntarily gave up his powers) by regaining his staff and book. Prospero has his servant Ariel create a massive hurricane which the Librarians are able to dispel, but he and Moriarty escape. Jenkins explains that the two are Fictionals, characters from classic literature who have managed to escape from their stories, and that their actions are largely dictated by how those same stories were originally written.

Flynn uses the Bolt of Zeus to destroy the Tree of Knowledge, while Eve uses Ariel as a bargaining chip to force Moriarty to leave.

In Oklahoma, while laying a new pipeline, the company owned by Jake's father, Isaac, accidentally releases an ancient spirit that feeds on lies and deceit. The lies Isaac told in order to get authorization to dig near a Choctaw burial ground give the entity the strength to escape just as the Librarians arrive posing as archeologists. Jake, who has kept his intelligence (not to mention his academic and intellectual achievements) secret from his alcoholic, demanding, contemptuous father, pretends to be Ezekiel's assistant. The entity, a shape-shifter, disguises itself as different people, trying to get its prison destroyed. Jake tells his father the truth about himself, but when Isaac says that he loves him, Jake recognizes the shapeshifter and pulls him down to the cavern.

There, they meet Lucy, a student who has been conducting experiments to determine whether or not magic is real. She explains that strange disappearances happen all the time on campus, and that no one bothers to investigate them. Stone gets into an argument with a professor, who is subsequently dragged away by a Lovecraftian entity. The team discovers that Lucy has accidentally summoned the creature through her experiments, but she is taken before they can act. As the entity targets anyone engaged in displays of hubris, Stone and Ezekiel trick it into opening a portal, which Cassandra enters to save Lucy. Before she can return herself, she is contacted by the Lady of the Lake (Beth Riesgraf), the leader of an all-female group dedicated to mastering science and magic.

Lucy drops out of Wexler to continue her studies, while Cassandra and Jenkins argue over whether or not the Librarians should be using magic rather than locking it away.

During a mission to recover the Eye of Zarathustra, the team encounters Flynn, only to be rendered unconscious by a spell.

A portal failure leaves him and Eve stranded together, and they agree to a temporary truce in order to find Flynn. Flynn realizes that Ray is a spirit of the Library, and that he has all of the missing artifacts. Using the Eye, the two access a Sumerian temple in rural Pennsylvania, where they find the Staff of Zarathustra.

Denning's opponent, who comes from a prominent local family, is revealed to have a contract with Mephistopheles (John DeLancie), who has been benefitting the family for years by causing terrible disasters that allow them to increase their power and influence. Eve steals the contract, but Sam betrays her and makes a deal of his own to trigger a natural gas explosion so that he can become a hero. With the other Librarians coming close to signing the contract as well, Eve tricks Mephistopheles into breaking his agreement by rendering himself mortal. Jenkins explains that a Guardian's job is not to protect the lives of Librarians; it's to protect their souls.

The club's owner turns out to be Dorian Gray, who has placed an enchantment on his painting that allows it to absorb the life energy of his patrons, ensuring that both it and him will always be beautiful. Jenkins reveals that Dorian is not a Fictional, but a real person, and that he knew him back when Oscar Wilde was writing his story. Stone and Ezekiel find the painting and destroy it, but Eve realizes that he has another, a digital version composed of hundreds of photographs of the patrons, one of whom is Cassandra.

The Librarians arrive just as the system overloads, severing their connection to the Library. As the group struggles to find a way out, Jones discovers that they are trapped in a simulation of a video game, with checkpoints, enemies, obstacles, item pickups, and timed events. Furthermore, the computer has placed the Librarians into a time loop, meaning every time they fail, they start at the beginning. As only he has any memories of what is happening, Ezekiel forces himself to repeat the loop over and over again until he can find a way out. Eventually, he manages to exploit a glitch in the game to get the others out, then kills himself to break the loop. The team briefly restarts the computer to revive him, but he appears to have no memories of his actions. Meanwhile, an increasingly desperate Jenkins summons Puck to ask when Prospero will strike next. The answer is: “Now!” Before Jenkins can warn the others, he suddenly forgets what he's doing and closes the Library for the night.

Flynn returns to the Library to find his team missing, with Jenkins having no memory of ever meeting them.

There, he finds them living alternate lives: Baird is the sheriff, with Moriarty (the mayor) as her fiancee, Stone is a respected professor and archeologist, Jones is an FBI agent, and Cassandra is a retired astronaut and TV personality. Carsen tries to convince them that their world is a fantasy, but they refuse to believe him. With Jenkins's help, Flynn tracks down Ariel, who has assumed a human form (Hayley McLaughlin), and binds her. She agrees to help them reverse her spell, as long as they agree to free her from Prospero's control. Prospero tempts them with false promises of fame and glory, which they reject. Upon returning to Portland, Eve finds Flynn in possession of Prospero's pocket watch, which he destroys to free Ariel. Jenkins greets them with the revelation that they have been gone for three weeks, during which Prospero has "supercharged" all of the world's ley lines using the Staff, which Flynn fears marks the beginning of the end of the world.

After stopping a rogue Moriarty from murdering Shakespeare, the duo discover that instead of The Tempest, his new work is The Triumph of Prospero. During a public reading, Shakespeare is suddenly possessed by Prospero, who intends to use his magic to conquer the world. Eve and Flynn recover Excalibur and use it to break Prospero's staff. Back in the present, the Librarians use clues and items left by Flynn to trap Prospero and exorcise him, returning Shakespeare to normal. A time rift opens that allows him to return to 1611, but leaves Flynn and Eve unable to return to their own time. Flynn has Shakespeare cast a spell that turns him and Eve into statues (mirroring the end of The Winter's Tale) and make arrangements for them to be stored in the Library, awakening 400 years later when the others find them.

They soon learn that the "reunion" is actually a peace summit between warring clans of Frost Giants who intend to seal their alliance by feasting on the crystal's power.

Jenkins arrives at the last second with an antidote, but Apep, who had been controlling Agnes all along, escapes.

With Charlene's help, Flynn defeats Lam and passes the staff to Stone, who returns it to Monkey. Grateful, Monkey gifts him with a spell that can "bring light where there is darkness." Back at the Library, Jenkins professes his love for Charlene before sending her to join Judson in an alternate dimension.

Baird gives Rockwell access to the Library in return for allowing her team to go free. She also acquires intelligence on the location of a mystical dreamcatcher within Mount Rushmore, which turns out to be a diversion planted by DOSA so that they can weaken the Library's defenses. Baird leads them to the treasure vault, where Rockwell turns Jenkins to stone using Medusa's head. Flynn sends the group to rescue him while he works to sabotage DOSA's efforts. They free him, but Apep soon escapes from Rockwell's custody and takes control of her body. Baird reveals that she and Flynn have been playing Apep from the beginning in order to vanquish him with the Eye of Ra. Apep detonates a bomb of pure evil inside the Library's catacombs and assumes a spectral form. Flynn uses the Eye to absorb Apep's power while Stone, Cassandra, and Ezekiel use their gifts to render him mortal, causing him to be consumed as the Eye's sacrifice. Rockwell agrees to return all of the artifacts to the Library and the Librarians resume their normal duties.

Eve and the others learn that the legend is wrong and the Civil War brothers actually reconciled before dying in a bomb blast, but Cassandra and Jenkins discover the Librarian brothers' feud really did cause the Dark Ages because they put their own egos ahead of their service to the Library.

His attempts to get back in the Library fail until he confides in Jeff's friends and co-workers, a group of techno-nerds and Dungeons and Dragons enthusiasts. They help him work his way back through the traps and challenges of the Library's back door. Meanwhile, the Librarians grow suspicious of the bumbling Jeff-as-Jenkins who, at length, confesses making the switch with a chance-acquired grimoire. Unfortunately, the book was the prison of Asmodeus, Duke of Hell. Using it weakened the spell binding him and he is now at large in the Library, searching for the gem that will free him completely. It's not there, as Jeff gave it to his mother. Azmodeus defeats the Librarians, but the real Jenkins returns in time to save Jeff. They then trail the demon back to Jeff's house and defeat him together. After regaining his true body, Jenkins continues his relationship with his new friends, becoming Dungeon Master of Jeff's D&D group.

To help make the decision, Stone reads a spell found by Cassandra, The Ritual of the One. All are taken to the Trial grounds where the Library, in possession of Jenkins, decrees a battle to the death leaving one Librarian, with Jenkins' life forfeit if the Librarians refuse. Cassandra, Stone, and Ezekiel are briefly transported to their worst nightmares where friends are recast as enemies, emerging with no memory of each other. A violent race to the finish ensues, each Librarian convinced the only way to save Jenkins is to kill the others, until Baird intervenes and convinces them not to murder one another. Jenkins is freed, but the Library still kills him. Enraged, Cassandra, Stone, and Ezekiel all resign, leaving the Librarianship vacant. A despairing Baird is visited by Nicole Noone, who explains that everything was part of her plan. Now that it has been abandoned and untethered, the Library fades out of reality, leaving Baird alone in a washed out alternate world.

The Librarians struggle to survive in the alternate world, chased by a bitter and angry Nicole. After their faith in the Library is restored, the Library itself returns, but Jenkins remains dead. Flynn chooses to use an artifact to travel back in time to when Nicole first became immortal in order to right his wrong of never going back for her. Flynn tells Nicole that she must remain in the past, but asks her to have her adventures for the Library instead of against it, something that she accepts. When Flynn returns to the present, time has been altered as a result of Nicole letting go of her bitterness. None of the evil Nicole caused has occurred and Jenkins is alive and immortal again. Flynn and Baird, the only ones who remember the world where Nicole was evil, undergo the tethering ceremony as Librarian and Guardian.
