Loki

In Asgard, a celestial kingdom ruled by the warrior-king Odin, two princes compete for the throne. Thor, the golden-haired elder son, embodies the warrior ideal Asgardians prize. His younger brother, Loki, possesses a secret talent for sorcery, a form of power Asgardian culture distrusts in its rulers. Loki hides his abilities at his father's insistence until the arrival of Amora, the apprentice of Odin's royal sorceress Karnilla. Amora is the first magic-wielder Loki has met besides his mother, Frigga. Unlike Loki, Amora practices magic openly as Karnilla's heir, but the two bond over their shared fascination with sorcery, and Amora begins teaching Loki spells in secret.

At a state feast, Odin unveils the Godseye Mirror, a sacred obsidian artifact that reveals visions of Asgard's future once per decade. When Odin peers into it, he recoils in terror and flees the hall. Loki disguises himself as a servant to eavesdrop on his father's private conversation and overhears that Odin saw one of his sons leading an army of the living dead against Asgard, a vision he believes foretells Ragnarok, the prophesied end of the world. When Loki and Thor discuss what they overheard, Thor assumes the traitorous son must be Loki. The assumption stings, but Loki cannot deny that the court would reach the same conclusion.

Desperate to see the vision for himself, Loki and Amora sneak into the vault. Loki disguises himself as Odin to bypass the magically sealed doors. When Amora channels energy into the Mirror, Loki sees a blurred image of soldiers pouring from the Bifrost, the rainbow bridge connecting Asgard to other realms, led by a figure he cannot identify. In his frustration, he accidentally releases his own power into the Mirror and shatters it. The explosion triggers another artifact that summons the Lurking Unknown, a creature that feeds on fear and grows with each terrified person it encounters. The creature rampages through the vault before Karnilla destroys it. Amora claims she alone broke the Mirror, shielding Loki to protect his standing as a contender for the throne.

Odin sentences Amora to banishment on Midgard (Earth), where the absence of ambient magic will slowly drain her powers and kill her. Loki wants to confess his role but stays silent as Amora is dragged away. Odin warns Loki privately that his title will not protect him, confirming that Loki is the son he saw in the Mirror. Loki resolves to be smarter and stealthier than Amora, to master his power and never reveal its full extent. Frigga, disagreeing with Odin's approach, secretly offers to teach Loki to control his magic, believing the true skill lies in owning one's power rather than being owned by it.

Years pass. Loki studies sorcery with Frigga and works to prove himself, but Odin increasingly favors Thor. When Odin sends the brothers to Alfheim, home of the Ice Elves, to brief them on the theft of five Norn Stones, powerful magical amplifiers taken from Karnilla, the mission deteriorates. Loki devises a plan to infiltrate the Elves' most secure location to prove their defenses inferior to Asgard's. The plan fails, and the brothers are captured. Thor deflects blame onto Loki, and Odin tells Loki his instincts are corrupt. As punishment, Odin assigns Loki to Midgard to assist the SHARP Society (Society for Hospitable Activities from Remote Planets), a small human organization that monitors interdimensional activity and has reported mysterious deaths in London.

Loki arrives in Victorian London and meets the Society's three members: Mrs. S., widow of the founder; Theo Bell, a young inventor who uses a cane and was once imprisoned for kissing another man, a criminal offense in Victorian England; and Gem, a police officer. They restrain his magic with Asgardian cuffs and treat him as a threat. When Loki attempts to return home through the fairy ring, a portal connecting the realms, he discovers Odin has blocked his passage. At a public morgue, Loki uses tinted spectacles Theo designed to reveal magical residue and confirms the deaths were caused by magic. When he accidentally touches a corpse while holding a spell, it briefly reanimates, echoing his father's vision of the living dead.

A calling card for a medium called "the Enchantress" found on the dead man leads Loki to the Inferno Club, a macabre entertainment venue. He recognizes the name as one he and Amora shared in their youth. During a séance show, Amora reveals herself, and they embrace in her dressing room. She explains that she has survived by siphoning life energy from humans, since for sorcerers, life force and magical power are intertwined. Loki realizes she is responsible for the living-dead corpses in London. When he returns the next day, they kiss beneath the stage.

Loki fabricates a cover story, claiming the deaths stem from a magical "virus" and that Amora's powers have become toxic on Earth without her knowledge. He proposes a public séance to convince a grieving family to authorize an autopsy, officially declaring the bodies dead so they can be buried. Theo vouches for Loki, and Mrs. S. reluctantly agrees. The séance succeeds, but a protestor named Rachel Bowman disrupts the show. Afterward, Amora drains Rachel's life force and kills her. Furious, Loki helps dispose of the body but tells Amora he is done. Before they part, Amora warns him to look at what Theo has been reading.

When the autopsies confirm the deaths and the bodies are scheduled for transport by rail to a cemetery, Loki contacts Thor through a magical communication bowl and asks him to meet at the Bifrost with soldiers. Haunted by Amora's warning, Loki then finds a book of Norse myths in Theo's flat. The entry describes him as vain, manipulative, a murderer, and the father of lies. He erupts at Theo, accusing the Society of judging him before he arrived, and cruelly tells Theo that Odin never cared about them.

Loki goes to Amora and reveals he stole the Norn Stones himself, intending to stage their recovery to impress Odin. Amora proposes they use the Stones to raise the train full of corpses as an army, invade Asgard through the fairy ring, and seize the throne. Loki agrees. They carve reanimation runes onto the tongues of each corpse at the morgue. Mrs. S. arrives, confronts Loki through the glass, and tells him everything is a choice. Amora appears behind Mrs. S. and slits her throat with Loki's knife. Loki watches, frozen.

On Sunday, Loki and Amora board the Necropolis Railway carrying the corpses to burial. Theo, barred from the train due to his criminal record, is smuggled aboard by Gem to attend Mrs. S.'s funeral. He spots Loki on the platform and creates a commotion to delay him. During the scuffle, Loki plants the Norn Stones in Theo's pocket. On the moving train, Loki confronts Amora, revealing he has deduced her true plan to take the Stones, kill him, and claim the throne herself. They fight across the rooftops. Amora begins raising the dead using her own fading life force. Loki stabs her with a Stone-amplified blade, and her body rapidly ages. She releases his hand rather than return to Asgard in defeat and is swept away, her fate unknown.

In the caboose, Loki confesses everything to Theo. Theo tells him the myths do not define him, that no one decides who Loki is except himself, and kisses him. Loki reveals he planted the Stones in Theo's pocket because Theo was the only person he trusted. Together they fight to the coupling between the passenger and hearse cars. Theo asks Loki to take him to Asgard, and Loki agrees. They uncouple the train, and then Loki throws Theo onto the passenger car, breaking his promise. As the gap widens, Theo watches with disappointment but no surprise. The hearse cars pass over the fairy ring, and Loki channels the Stones to open the Bifrost, pulling himself and the dead into Asgard.

The train crashes onto the Rainbow Bridge, and the reanimated dead climb from the wreckage, recreating Odin's vision. Thor waits with soldiers. For a moment, Loki considers marching on the capital. Instead, he takes Thor's outstretched hand and channels all five Norn Stones to destroy every corpse on the bridge.

In the throne room, Loki presents the Stones to Odin. His father offers an easy excuse, asking if Amora enchanted him. Loki refuses it, stating that all his choices were his own. Odin declares Loki unfit to be king and announces he will name Thor as heir. Loki challenges his father, asking if Odin needed a villain to make Thor look worthy. Odin silences him. Alone, Loki resolves that if he cannot be king, hero, or brother, he will be the trickster, the schemer, the God of Mischief. He will serve no heart but his own.
