09 · World and setting

Worldbuilding describes the conditions under which a story operates. Setting specifies the place and time of an event. Design enough of the world to explain choices, limits, and visible details; a complete fictional encyclopedia is not a prerequisite for a compelling scene.

The entries here are working creative definitions. Geographic and social terms retain wider meanings outside filmmaking. They are prompts for inquiry, not a formula for classifying real communities.

Physical world

Era#

Definition. The historical or imagined period in which events occur, with its available technologies, institutions, and cultural assumptions. An era may be precisely dated or deliberately approximate.

Use. Establish what characters consider ordinary and what would be impossible, novel, or controversial.

Example. A port drama set before reliable radio makes a missing ship an information problem as well as a rescue problem.

Geography#

Definition. The arrangement of terrain, waterways, distances, borders, and routes that gives the story world its spatial logic. Geography includes relationships between places, not just attractive scenery.

Use. Make travel, trade, isolation, defense, and encounters understandable.

Example. A river separates the hospital from the power station; the only bridge becomes a recurring point of conflict during blackouts.

Climate#

Definition. The usual patterns of temperature, precipitation, and other atmospheric conditions over extended periods. Climate shapes everyday adaptations; weather describes a particular short-term condition.

Use. Connect architecture, clothing, work schedules, and food production to their environment.

Example. A settlement accustomed to prolonged heat has shaded streets and nighttime markets even when the current scene happens on a mild day.

Ecology#

Definition. The relationships among organisms and their environment, including food, water, waste, competition, and regeneration. A fictional ecosystem becomes more convincing when its parts affect one another.

Use. Give survival problems and environmental changes concrete consequences.

Example. Polluted canals reduce insect life, then fish stocks, forcing the community to abandon a familiar source of food.

Settlement#

Definition. A place where a population lives, together with its distribution and organization: village, town, city, camp, dispersed homesteads, or another arrangement.

Use. Establish density, access, anonymity, dependence, and likely social encounters.

Example. In a compact hillside village, everyone sees a newcomer arrive; in an enormous transit city, the same arrival can remain unnoticed.

Architecture#

Definition. The design and construction of buildings and built spaces, including layout, structure, circulation, materials, and their cultural meaning.

Use. Translate the world's priorities into spaces that characters must physically navigate.

Example. An administration building places public waiting rooms far below private offices, making hierarchy visible through the visitor's journey rather than a speech.

Infrastructure#

Definition. The systems that enable everyday activity, such as water, energy, transport, communications, sanitation, and distribution. Their maintenance and ownership are part of the world.

Use. Identify dependencies and reveal who keeps a society functioning.

Example. A neighborhood's evening routine follows the two hours when its shared generator can power pumps and cooking equipment.

Social world

Institutions#

Definition. Durable organizations, rules, and practices that organize collective life: courts, schools, guilds, religious bodies, councils, and similar structures.

Use. Give authority and opposition specific procedures rather than an abstract label such as “the system.”

Example. A repair guild controls certification; an ingenious unlicensed mechanic can fix the machine but cannot legally return it to service.

Class#

Definition. A structure of social positions shaped by resources, work, ownership, status, and power. The relevant divisions depend on the world and are not always reducible to wealth.

Use. Show unequal access, conflicting interests, and different expectations of the same event.

Example. Water engineers receive secure housing while wealthy traders still queue for permits, complicating a simple rich-versus-poor hierarchy.

Economy#

Definition. The ways a society produces, distributes, exchanges, and consumes goods and services. Money is only one possible coordinating mechanism.

Use. Explain scarcity, incentives, obligations, and the practical cost of choices.

Example. A harbor community allocates fuel through work credits, so a rescue mission requires volunteers to surrender part of their winter allowance.

Customs#

Definition. Familiar practices and expectations learned through participation in a community. Customs may be informal, contested, or different across generations.

Use. Communicate belonging and friction through ordinary behavior rather than exposition.

Example. Visitors leave their tools at the communal doorway; a stranger keeping a knife on their belt inadvertently signals distrust.

Rituals#

Definition. Repeated, patterned actions carrying shared significance, often marking a transition, obligation, belief, or membership. Rituals can be religious or secular.

Use. Give a community's values an observable form and create opportunities for variation or refusal.

Example. Before launching a repaired boat, every worker touches its nameplate; one person's refusal makes an unresolved dispute visible.

Language#

Definition. The systems of expression people use, including speech, signing, writing, specialized vocabularies, and conventions of address. Language also changes across situations and communities.

Use. Establish access, expertise, intimacy, and misunderstanding without making accent a substitute for character.

Example. Two rivals switch from formal titles to an old workshop shorthand when an emergency forces them to cooperate.

Belief systems#

Definition. Connected ideas about reality, value, authority, and obligation that inform how people interpret events. Members of a community need not hold identical beliefs.

Use. Make decisions understandable from inside a character's worldview.

Example. Some residents regard abandoned machines as shared inheritance; others believe reopening them violates a duty to the dead.

Possibility and limitation

Technology#

Definition. Tools, techniques, and systems through which people accomplish tasks. A world's technology includes maintenance, skills, supply chains, and access as well as devices.

Use. Establish reliable capabilities and meaningful limits before they become plot solutions.

Example. Portable batteries are powerful but their connectors are scarce, so a courier guards an adapter more carefully than the battery itself.

Magic#

Definition. Supernatural or extraordinary capabilities treated as part of a fictional world's possibilities. Magic may have explicit rules or remain mysterious within the chosen storytelling approach.

Use. Decide what characters and audiences can reasonably expect, especially when magic resolves conflict.

Example. A healer can transfer pain but cannot remove it, making every successful treatment a difficult interpersonal choice.

World rules#

Definition. Statements of what consistently can, cannot, or tends to happen in a fictional world. They can describe physical, social, supernatural, or institutional conditions.

Use. Support coherent consequences while separating objective rules from a character's mistaken beliefs.

Example. Machines cannot operate beyond the city's signal towers; a later exception requires an explanation rather than silent rule replacement.

Limitations#

Definition. Boundaries on an ability, resource, system, or institution. A limitation describes what a capability cannot accomplish or the conditions in which it fails.

Use. Keep powerful resources from dissolving every obstacle and generate alternative tactics.

Example. An aerial camera can map rooftops but cannot distinguish people inside buildings, leaving the investigator dependent on local testimony.

Costs#

Definition. The expenditure, loss, risk, or obligation incurred by an action or capability. A cost may be immediate, delayed, personal, or borne by someone else.

Use. Turn otherwise obvious solutions into choices with consequences.

Example. Heating the clinic tonight consumes fuel reserved for tomorrow's water deliveries, so the decision redistributes harm rather than eliminating it.

Taboos#

Definition. Strong social prohibitions whose violation carries moral, spiritual, or communal significance. A taboo is not necessarily identical to a written law.

Use. Explain why a technically possible action remains difficult to take openly.

Example. Entering abandoned family homes is forbidden even when useful materials are visible through broken windows, forcing scavengers to negotiate exceptions.

Kinds of place

Public space#

Definition. A space used by a wider community, with access governed by local norms or rules. Public use does not necessarily imply public ownership or equal freedom to remain there.

Use. Stage visibility, accidental encounters, collective activity, and contested belonging.

Example. A market square allows a private argument to acquire witnesses, allies, and social consequences.

Private space#

Definition. A space whose access is restricted or understood to belong to particular people or groups. Privacy may be physical, social, or temporary.

Use. Establish boundaries, trust, intrusion, and differences between public and private behavior.

Example. A guarded storeroom becomes emotionally significant when its owner gives another character a key without explanation.

Domestic space#

Definition. A space associated with living, care, rest, household work, and personal routine. Domestic space can be shared, improvised, institutional, or mobile.

Use. Reveal relationships through habits, possessions, and the distribution of labor.

Example. Two estranged siblings still prepare breakfast around each other's movements without speaking, showing a shared history through spatial familiarity.

Workplace#

Definition. A setting organized around labor, tasks, responsibilities, and working relationships. It may overlap with a home, vehicle, street, or institution.

Use. Generate recurring encounters and show competence, hierarchy, solidarity, or exploitation in action.

Example. A night-shift control room keeps rivals together long enough for a technical disagreement to expose a deeper conflict.

Wilderness#

Definition. A setting framed as relatively outside the story's dominant built or managed environment. This is a perspective-dependent designation, not proof that a place is uninhabited or without history.

Use. Explore unfamiliarity, exposure, navigation, and competing relationships to land.

Example. Outsiders call a forest empty while their guide recognizes cultivated paths and seasonal gathering sites.

Frontier#

Definition. A boundary zone between jurisdictions, systems, settlements, or imagined possibilities. Who describes it as a frontier matters, especially when expansion obscures existing inhabitants.

Use. Stage uncertain authority and encounters between incompatible assumptions.

Example. A repair station sits where two cities' communication networks end, making it a bargaining point rather than an uncontested outpost.

Transit space#

Definition. A place organized around movement between destinations, such as a station, ferry, corridor, checkpoint, or airport. Waiting is often as important as travel.

Use. Put otherwise separate characters together and attach decisions to departure or arrival.

Example. A delayed ferry creates a temporary community whose members must decide whether to share a limited shelter.

Scene conditions

Interior#

Definition. A scene staged within an enclosed location, commonly marked INT. in screenplay headings. The designation describes the represented space; an interior can be filmed on a constructed set.

Use. Specify spatial enclosure and practical conditions for staging, light, and sound.

Example. A nighttime kitchen scene is interior even when the kitchen set occupies an outdoor studio backlot.

Exterior#

Definition. A scene staged in an outdoor location, commonly marked EXT. in screenplay headings. It describes the fictional location, not simply whether the camera is outdoors.

Use. Clarify exposure to weather, visible surroundings, and movement through open space.

Example. A conversation on a covered station platform remains an exterior setting despite partial shelter.

Day#

Definition. A broad scene-time designation indicating daylight hours in the story. It does not specify a particular sun angle, weather condition, or exposure treatment.

Use. Establish time continuity, then add more specific lighting intentions where needed.

Example. Two daytime scenes can have very different appearances: an overcast morning street and a bright late-afternoon courtyard.

Night#

Definition. A scene-time designation indicating nighttime in the story. Visibility may come from moonlight, practical fixtures, artificial sources, or stylized treatment; night does not mean an unreadable image.

Use. Coordinate story time, daily routines, and the intended sources of illumination.

Example. A busy night market is brightly illuminated while the adjacent residential alley remains mostly dark.

Dawn#

Definition. The transition toward daylight around the beginning of the day. Its visible duration and character vary with geography, season, and weather.

Use. Connect a scene to changing activity and light without assuming one universal emotional meaning.

Example. Workers finish repairing a pump as the first customers arrive, making dawn a deadline rather than merely a hopeful image.

Dusk#

Definition. The transition from daylight toward darkness at the end of the day. It is a changing interval rather than a single fixed color or exposure.

Use. Stage closing routines, reduced visibility, and a shift in how spaces are used.

Example. A public courtyard empties as vendors pack away, leaving two characters increasingly exposed to one another.

Weather#

Definition. The atmospheric conditions at a particular time and place: rain, wind, snow, fog, heat, and related conditions. Weather affects action as well as appearance.

Use. Connect atmosphere to practical consequences and continuity across shots.

Example. Wind prevents a character from hearing an approaching bicycle; wet clothes persist when the scene moves indoors.

Season#

Definition. A recurring portion of the year associated with particular environmental, agricultural, or social patterns. Some worlds organize seasons around rainfall or other cycles rather than four temperate divisions.

Use. Establish resources, daylight patterns, clothing, labor, and recurring events.

Example. A flood-season ferry service becomes the only connection between districts that are walkable during dry months.

Practical distinctions

World facts, character beliefs, and production choices need separate records. A character may believe a mountain is impassable; the geography record can leave that unresolved. A blue color grade is a visual treatment, not evidence that the fictional climate is cold.

The INT./EXT., location, and day/night heading convention is illustrated in the BBC television screenplay format guide. More specific setting details belong in action, production notes, or structured fields as appropriate; a particular format guide is not universal across every production.

Visual interaction and structured fields

These are interaction proposals. Geographic coordinates, distances, and dates remain unknown unless the project has actually established them.
