The Author Glossary
20 essential craft terms every fiction writer should know, with practical examples and how EPOS AI helps you apply them.
Hero's Journey
The narrative pattern described by Joseph Campbell in which a hero leaves the familiar world, faces trials, and returns transformed. The foundation of countless novels, films, and myths, from the Odyssey to Harry Potter.
Apply it with EPOS AI →Plot Arc
The dramatic trajectory of a story from exposition through rising action, climax, falling action, and resolution. A well-constructed plot arc keeps readers engaged from first page to last.
Apply it with EPOS AI →Plot Twist
An unexpected turn of events that upends the reader's understanding of the story. Effective plot twists are logical in retrospect but genuinely surprising in the moment.
Apply it with EPOS AI →Show, Don't Tell
The principle of conveying emotions and character traits through action, dialogue, and sensory detail rather than direct statement. Instead of "He was angry": "His knuckles whitened as he gripped the armrest."
Apply it with EPOS AI →Worldbuilding
The process of creating a fictional world with its own geography, history, culture, magic, or technology. Essential in fantasy, science fiction, and historical fiction.
Apply it with EPOS AI →Character Arc
The inner transformation of a character over the course of the story. From insecure apprentice to confident hero, from cynic to believer, a strong character arc makes figures three-dimensional and unforgettable.
Apply it with EPOS AI →Point of View (POV)
The perspective from which a story is told: first person, close third person, omniscient, or, rarely, second person. The choice shapes emotional proximity, tension, and the flow of information.
Apply it with EPOS AI →Foreshadowing
Planting subtle hints of future events in the narrative. Master foreshadowing is almost invisible on first read, unmistakable on the second.
Apply it with EPOS AI →Pacing
The narrative tempo of a story, the rhythm between fast-moving action scenes and slower, reflective moments. Good pacing prevents readers from feeling bored or overwhelmed.
Apply it with EPOS AI →Three-Act Structure
The classic narrative model of Setup (Act 1), Confrontation (Act 2), and Resolution (Act 3). Most successful novels and films follow this structure, consciously or not.
Apply it with EPOS AI →Antagonist
The opposing force to the protagonist. Not necessarily a villain, an antagonist can be a person, a society, nature, or an internal conflict. The stronger the antagonist, the stronger the story.
Apply it with EPOS AI →Throughline
The central theme or main narrative thread that runs through the entire story and holds all elements together. Without a clear throughline, a story feels episodic and disconnected.
Apply it with EPOS AI →Exposition
The introduction of background information readers need to understand the story: setting, characters, initial situation. The art lies in weaving exposition invisibly into the action.
Apply it with EPOS AI →Unreliable Narrator
A narrator whose account of events is distorted, incomplete, or deliberately misleading. A powerful tool for tension and plot twists, the reader must decide what is true.
Apply it with EPOS AI →MacGuffin
An object or goal that drives the plot, but whose actual nature is secondary. The briefcase in Pulp Fiction, the Ring in Lord of the Rings, what matters is the chase, not the object itself.
Apply it with EPOS AI →Cliffhanger
An unresolved, tension-filled chapter or episode ending that compels the reader to continue. Named after the image of a hero literally hanging from a cliff.
Apply it with EPOS AI →Subplot
A secondary storyline that complements, enriches, or contrasts the main plot. Good subplots mirror the central theme and give supporting characters depth and agency.
Apply it with EPOS AI →Character Constellation
The web of relationships between all characters in a story. Who is in conflict, who is allied? A well-designed constellation generates natural tension and emotional complexity.
Apply it with EPOS AI →Revision
The process of improving a first draft: tightening structure, sharpening dialogue, cutting redundancies, fixing inconsistencies. Professional authors typically revise their manuscripts three to five times.
Apply it with EPOS AI →Manuscript Formatting
The standardised preparation of a manuscript for publishers or self-publishing: standard page format, font, margins, chapter breaks. Correct formatting signals professionalism to agents and editors.
