Foundations
Transportation in Thesalon is a connected system rather than a list of roads and sea lanes.
A journey can fail even when the route itself remains open. A harbor may be accessible but unable to unload cargo. A mountain pass may be clear while the road beyond it is closed. A ship may arrive on time but wait days for pilotage, inspection, quarantine, or a connecting convoy. A courier may travel faster than a merchant vessel but still lose time when messages must cross legal or linguistic boundaries.
The Foundations section explains the shared rules behind those situations. These rules apply across every continent, although each region uses different infrastructure, authorities, vehicles, signals, and seasonal practices.
This map is schematic. It preserves continental relationships and representative connections. It does not establish exact coastlines, route classifications, travel times, seasonal availability, or legal access.
What Makes Movement Possible
A usable transportation connection normally requires seven things to work together.
| Foundation | Practical question |
|---|---|
| Route hierarchy | How important is this corridor, and what happens when it closes? |
| Geography of movement | What physical features make the route possible or force it into a particular path? |
| Transfer networks | Where do passengers, cargo, messages, and authority change transport mode? |
| Communication networks | How do travelers learn about closures, schedules, hazards, inspections, and route conditions? |
| Transportation law and authority | Who can permit, inspect, tax, redirect, protect, or close movement? |
| Seasonal travel | When is the route usable, and how does its operation change during the year? |
| Travel times and navigation | How long does the full journey take once delays, transfers, weather, and wayfinding are included? |
These questions should be answered before a route is treated as reliable.
The Basic Movement Chain
Most journeys follow the same operational structure even when the vehicles and terrain differ.

DESTINATIONA sea voyage may begin with a road or river journey to a harbor. A river journey may require a ferry, canal lock, warehouse district, or coastal vessel at its downstream end. A mountain crossing may depend upon a pass settlement, guide service, winter shelter, or legal checkpoint. An island journey may require several harbor transfers rather than one direct voyage.
The transfer points are often more important than the longest segment of the journey. They determine whether cargo can be stored, whether passengers can find onward passage, whether authorities recognize the traveler’s documents, and whether an alternate route exists when the expected connection fails.
World Transportation Principles
Geography creates the corridor
Rivers, coastlines, straits, reefs, mountain passes, wetlands, forests, deserts, glaciers, and prevailing winds determine where repeated movement can occur.
Infrastructure can improve a corridor, but it cannot ignore the geography that created it. A road through a mountain system still depends upon the usable pass. A harbor still depends upon depth, shelter, tides, and an approach channel. A desert road still depends upon water.
Repeated need creates infrastructure
Routes become permanent when settlements, markets, farms, courts, temples, military commands, and harbors depend upon them often enough to justify maintenance.
That maintenance may include roads, bridges, ferries, locks, docks, warehouses, shelters, charts, pilots, beacons, patrols, surveyors, or seasonal work crews.
Transfer points create major settlements
Important settlements frequently stand where movement changes mode:
- river to sea;
- road to river;
- mountain road to valley road;
- caravan to ship;
- coastal vessel to ocean-going vessel;
- public route to controlled route;
- material route to conditional planar passage.
Transfer settlements accumulate storage, lodging, labor, inspection offices, markets, repair services, guides, and information.
Information is transportation infrastructure
A route cannot operate safely without current information.
Travelers need to know about storms, flood levels, ice, damaged bridges, closed gates, quarantine, military activity, toll changes, pilot requirements, missing beacons, and delayed convoys. Courier systems, harbor notices, signal towers, river warnings, route stations, and local guides are therefore part of the transportation network.
Authority follows movement
Transportation creates points where governments, councils, temples, military commands, harbor authorities, pilots, guilds, clans, and local communities can exercise control.
Their authority may apply to a harbor, bridge, pass, river reach, caravan station, inspection yard, road segment, or seasonal crossing. It should not automatically be interpreted as a fixed political border.
Season changes the network
The same route can operate differently at different times of year.
Ice may create temporary roads while closing harbors. Floodwater may improve barge travel while destroying nearby roads. Storm seasons may stop open-water passages but increase demand for protected coastal routes. Dry seasons may open desert travel while reducing river depth.
A route description is incomplete unless it explains when the route operates and what changes when conditions worsen.
Travel time includes waiting
Travel time is not distance divided by speed.
A complete estimate includes:
- local travel to the route;
- waiting for departure;
- loading and unloading;
- pilot or guide transfer;
- inspections and customs;
- convoy assembly;
- river, tide, wind, or weather delays;
- overnight or seasonal stoppages;
- transfer between transportation modes;
- final travel from the last major node.
Published travel times are expected operational ranges, not guarantees.
Foundation Topics
Route Hierarchy
Route hierarchy explains why some corridors are main and others are secondary.
It separates operational importance from physical size, distance, legality, and difficulty. A narrow mountain pass can be a main route when no equivalent crossing exists. A long sea passage can remain secondary when stronger alternatives carry most regular traffic.
Use this page to determine:
- the consequences of route closure;
- whether alternatives are equivalent;
- what level of maintenance and authority a route attracts;
- whether a corridor serves mixed traffic or a specialized purpose.
Map: main and secondary corridors, major transfer nodes, and representative alternate routes.

Geography of Movement
Geography of Movement explains how terrain and water create transportation corridors.
It covers rivers, coasts, open seas, islands, reefs, mountain systems, wetlands, forests, deserts, glaciers, and natural chokepoints. It also explains why each continent developed a different transportation pattern.
Use this page to determine:
- why a route follows its current path;
- where movement becomes concentrated;
- which physical barriers prevent easy alternatives;
- how continental geography affects transportation mode.
Map: terrain-driven corridors, watershed movement, navigable coasts, passes, and geographic barriers.

Transfer Networks
Transfer Networks explains what happens where journeys change mode.
Ports, river landings, locks, ferries, caravan stations, road junctions, pass settlements, warehouses, and inspection yards allow movement to continue across different systems.
Use this page to determine:
- where cargo must be unloaded or repacked;
- where passengers wait for onward travel;
- where delays and shortages accumulate;
- which settlements become essential because several systems meet there.
Map: major transfer nodes and the transportation modes connected at each one.
Continue to: Transfer Networks
Communication Networks
Communication Networks explains how route information moves.
The page covers couriers, packet services, harbor notices, beacon chains, pilot signals, river warnings, administrative dispatches, emergency signals, and local reporting practices.
Use this page to determine:
- how travelers learn that a route has changed;
- how authorities announce closures or inspections;
- how ships, convoys, ferries, and route stations coordinate movement;
- where information becomes delayed, distorted, or unavailable.
Map: beacon chains, courier corridors, warning systems, and communication gaps.
Continue to: Communication Networks
Transportation Law and Authority
Transportation Law and Authority explains who controls movement and what that control permits.
The page distinguishes political territory from operational jurisdiction. A harbor authority may regulate ships without governing the surrounding region. A temple may control a pilgrimage crossing. A military command may close a pass. A pilot organization may determine who can enter a dangerous channel.
Use this page to determine:
- what documents, fees, inspections, or escorts are required;
- who can legally close or redirect a route;
- where authority overlaps or conflicts;
- how quarantine, salvage, customs, and convoy law operate.
Map: transportation jurisdictions, controlled gateways, inspection points, and overlapping authority zones.

Seasonal Travel
Seasonal Travel explains how the usable network changes during the year.
The page covers flood cycles, sea ice, storm seasons, prevailing winds, drought, river depth, harvest movement, migrations, ecological closures, and temporary roads.
Use this page to determine:
- when a route normally opens or closes;
- which routes become faster or more dangerous in a particular season;
- when temporary alternatives appear;
- how weather and ecology change supply, traffic, and delay.
Map: seasonal opening windows, flood and ice zones, storm corridors, and temporary routes.
Continue to: Seasonal Travel
Travel Times and Navigation
Travel Times and Navigation explains how journeys are measured and planned.
The page provides the assumptions used for road, river, coastal, ocean, mountain, wetland, desert, and conditional travel. It also establishes how charts, pilots, landmarks, instruments, guides, schedules, and delays affect the final estimate.
Use this page to determine:
- the expected duration of a complete journey;
- which stages require specialist navigation;
- where waiting time must be added;
- what conditions can substantially change the estimate.
Map: standard journey bands, navigational dependency, and major delay points.

Maps in the Foundations Section
Every Foundations article should include at least one transportation map or operational schematic.
The map must answer the page’s central practical question rather than repeat the general world map. Maps should use the same stable settlement and location names used by the continental atlases and route registries.
| Page | Required map focus |
|---|---|
| Foundations | World arrangement, gateway nodes, representative connections, and frontier transfers |
| Route Hierarchy | Main routes, secondary routes, alternate corridors, and closure-sensitive nodes |
| Geography of Movement | Rivers, coasts, passes, deserts, wetlands, forests, reefs, glaciers, and chokepoints |
| Transfer Networks | Harbors, river ports, locks, ferries, caravan exchanges, pass settlements, and warehouses |
| Communication Networks | Courier lines, packet routes, beacon chains, warning systems, and communication gaps |
| Transportation Law and Authority | Controlled gateways, pilotage zones, inspections, quarantine, customs, and overlapping jurisdiction |
| Seasonal Travel | Ice, flood, storm, drought, wind, ecological restrictions, and temporary routes |
| Travel Times and Navigation | Journey-duration bands, required pilots or guides, transfer delays, and navigational difficulty |
Regional maps should use the approved continent atlases as their physical base. They should not introduce new coastlines, settlements, rivers, passes, or completed roads.
Planning a Journey
When planning travel through the website, answer these questions in order:
- What is the origin and destination?
- Which physical corridor connects them?
- Is the corridor main, secondary, seasonal, restricted, hidden, or conditional?
- Where must the traveler transfer between transportation modes?
- What current route information is required?
- Which authorities inspect, tax, permit, escort, or close the journey?
- What seasonal conditions apply?
- What waiting, transfer, and navigation delays must be added?
- What alternative exists if the expected route fails?
The remaining transportation pages provide the detailed routes, services, authorities, hazards, schedules, and travel times needed to answer those questions.
