The End of Eternity (1987) Timeline Explained – Every Event in Order

Harlan shows Cooper the Time Capsule during his training as a Technician. While teaching Cooper about Primitive Earth history, Harlan becomes so passionate about the subject, something he's cherished since childhood, that he carelessly demonstrates the forbidden device. This violation of Eternity's strict rules results in his exile to the 48th century as an Observer.

Eternity is a clandestine organization that exists outside of time, capable of traveling to any century through Time Capsules and Sockets of Time. It controls Earth's fate by manipulating history from the 27th century onward. Recruits are taken as children and trained as Observers, Computers, Sociologists, or Technicians. The organization maintains strict rules about technology, particularly the Time Capsule device, which is forbidden for most members.

Twissel plans to close the circle of Time by establishing Eternity's founding in the past. The memoir describes how Mullanson, the founder Eternity claims, received training that led to creating the first time travel device. By sending the memoir to the 24th century with Twissel and Harlan's names attached, he ensures the memoir serves as a blueprint to construct a timeline favorable to Eternity and anchor it in the 27th century.

Finge decides to alter the 48th-century reality specifically to erase Noÿs Lambent. The exact motivation isn't fully detailed, but his action threatens to remove Noÿs entirely from Harlan's world. This erasure would eliminate any possibility of their relationship and represents Finge's power to reshape timelines according to the Computer's will, demonstrating the dangerous control Computers wield over human destinies.

The Hidden Centuries are a stagnant pocket of time beyond the 1000th century, representing a refuge where escape from Eternity seems impossible. After learning that Noÿs has been erased from the altered timeline, Harlan hides her there to protect her from being completely deleted from existence. The act isolates them both from Eternity's reach, making reunion appear impossible but also placing Noÿs beyond Finge's ability to erase.

Harlan becomes Eternity's enemy because the organization attempts to erase Noÿs from reality. When Finge alters the 48th century and removes Noÿs from existence, Harlan refuses to accept this outcome. He hides Noÿs in the Hidden Centuries, defies the Council, and threatens Eternity itself to secure their reunion. He chooses personal love over his duty to the organization that trained him, becoming a rebel willing to unravel the institution that defined his existence.

Noÿs Lambent is remarkable because women are extremely scarce in the 48th century, making her presence as Finge's secretary a startling anomaly. This scarcity makes her relationship with Harlan even more significant and creates tension, as a romantic connection between an Eternal and a mortal woman threatens the carefully controlled social structure that Eternity maintains across centuries.

Closing the circle refers to Twissel's plan to solidify Eternity's control over all of history. By sending Cooper's pupil to the 24th century, Twissel aims to ensure that Mullanson, the founder, receives proper training and creates the first time travel device. This would anchor Eternity's founding in the 27th century and create a self-reinforcing loop where the organization's existence is guaranteed throughout all of history.

The Time Capsule stalls in the 1000th century as a direct consequence of the timeline manipulation. When Finge alters reality and Harlan hides Noÿs in the Hidden Centuries, the Time Capsule becomes frozen and unable to pass beyond the 1000th century. This blocks Harlan's ability to reach Noÿs through normal time travel, forcing him to find alternative methods and demonstrating the physical consequences of altering time so profoundly.

After Harlan shows Cooper the Time Capsule, both a forbidden act, Harlan receives punishment while Cooper's fate is less clearly defined in the summary. Harlan is reassigned as an Observer to the 48th century sector under Computer Finge's control. This exile marks the beginning of his personal rebellion, as he transitions from a promising Technician to a defian Eternal who will eventually oppose the entire organization.

Noÿs Lambent temporarily works as a secretary for Computer Finge in the 48th century. This is unusual because women are scarce in that era. Her position as Finge's secretary provides the circumstances for her to meet Harlan, and her role bridging the mortal and Eternal worlds creates the foundation for their forbidden romance that ultimately drives the film's central conflict.

The Mullanson memoir, discovered in Eternity's archives, describes how Mullanson, the founder Eternity claims, received training that led to creating the first time travel device. The memoir serves as a detailed blueprint for establishing Eternity's control. When Twissel sends it to the 24th century with his and Harlan's names included, it reveals that Twissel and Harlan's fates are deeply intertwined with Eternity's grand design, adding a layer of predetermined destiny to the story.
