The Lantern Cartographers

“The beeswax road to Thornfield takes four hours on foot. The tallow road takes two, but it passes through a market that has been abandoned for a century and still smells like fresh bread. The phosphor road takes fifteen minutes and arrives at a Thornfield that does not match any existing survey. I have mapped all three. I recommend the beeswax.”

• Cartographer Wynn, field notes

1. Setting Overview & Tone

The visible world is one layer of a place with many. Beneath the ordinary landscape of roads, fields, and towns lies a network of paths that respond to light. These paths are not metaphorical. They are physical roads with surfaces, landmarks, and weather. They exist only while illuminated by the correct fuel, and they connect places in ways that ordinary geography does not allow. The Cartographers’ job is to map them, which is difficult because the roads change depending on what you burn and because some roads lead to places that do not want to be found.

Tone: Adventurous, methodical, and gently eerie. The setting combines the satisfaction of exploration with the discomfort of discovering that someone else explored first. The Cartographers are professional, practical people who carry calibrated lanterns, annotated fuel lists, and backup wicks. They are also people who regularly walk through landscapes that should not exist and return to the visible world with maps that contradict each other.

Sensory Pillars:

1. Sight: A Lantern Road appearing: darkness resolving into a path as the lantern’s circle of light touches ground that was not there a moment ago. The road surface varies by fuel: beeswax roads are packed earth with milestones, tallow roads are cobblestone with market stalls, phosphor roads are smooth stone of a color that does not occur in nature. The boundary of the light, beyond which the road simply stops, is sharp and absolute.
2. Sound: Footsteps on a road that produces no echo, because the landscape beyond the lantern’s reach does not reflect sound. The crackle of a lantern wick, which is louder on a Lantern Road, as if the flame is working harder. Distant sounds from the road’s destination, arriving before the destination is visible: birdsong from a forest three miles ahead, or conversation from a market that closed a century ago.
3. Touch & Smell: The warmth of a lantern against the hip, which is the most reassuring sensation on a Lantern Road. The specific smell of each fuel: beeswax (sweet, warm), tallow (sharp, animal), phosphor (metallic, cold). The temperature of the Lantern Road air, which is always slightly cooler than the visible world, as if light is the only source of warmth here.

2. The Lantern Roads

Beeswax Roads are the most commonly mapped. They connect established settlements through merchant-safe routes. The roads are well-maintained, the landmarks are reliable, and the distances are shorter than surface travel. Most commercial Cartographers specialize in beeswax mapping.

Tallow Roads are older and less predictable. They pass through abandoned places: empty markets, ruined estates, and towns that the visible world has forgotten. The roads are useful shortcuts, but their landmarks shift, and some routes dead-end at locations that no longer exist on the surface. Tallow specialists are considered eccentric.

Phosphor Roads are rare, ancient, and unsettling. They predate human settlement and connect places that have no surface equivalent. The roads are smooth, well-maintained, and lit at intervals by phosphor lamps that no Cartographer placed. Someone built these roads and continues to service them. The Cartographers have not yet met the maintenance crew.

The Junction Archives are the Guild’s headquarters: a library of every mapped road, maintained in a converted warehouse that sits on a convergence point where all three road types overlap. The Archives’ lanterns are always lit because the building exists partially on a Lantern Road and going dark would cause structural problems.

3. Factions

The Cartographers’ Guild maps and sells passage on the Lantern Roads. Guildmaster Tomas Vael is a careful administrator who maintains quality standards and licensing protocols. He is also a beeswax conservative who considers phosphor mapping dangerously irresponsible. The Guild’s revenue depends on commercial beeswax routes, and the phosphor roads, if made public, would disrupt the entire business model.

The Fuel Merchants supply the specialized fuels that reveal different roads. They control a supply chain that is more powerful than it appears: without the right fuel, the Cartographers cannot work. The leading merchant house, Brenner and Sons, has recently acquired a monopoly on phosphor supply and is demanding a percentage of all phosphor-mapped routes in exchange for continued sales.

The Roadkeepers are a recently discovered faction. The Cartographers found them on the phosphor roads: people (or something resembling people) who maintain the ancient route network. They communicate through patterns of light left at road junctions, and their messages have been partially translated. The Roadkeepers appear to have been maintaining the phosphor roads for centuries. They are aware of the Cartographers. They have not decided whether this awareness is friendly.

The Surface Authorities are the governments and landowners of the visible world. They are increasingly nervous about a road network that bypasses their borders, toll stations, and military defenses. Several governments have attempted to regulate the Lantern Roads. Regulating a road that does not exist when unlit has proven difficult.

4. Unique Mechanic: Lamp Fuel Clock

Each expedition starts with a 6-segment Fuel Clock.

Fuel depletion (+1 segment):

• One significant travel scene on a Lantern Road
• An encounter or exploration that requires the lantern to remain lit while stationary
• Environmental interference (wind, moisture, interference from a competing fuel type)
• Using the lantern for illumination beyond its road-revealing function

At 0 Fuel: The lanterns go out. The Lantern Road disappears. The party is deposited at whatever point on the surface world corresponds to their current position on the road. This position may not match their expectations. A party traveling a beeswax road at depletion may emerge in the correct general area. A party on a phosphor road may emerge somewhere that has never been mapped.

Fuel switching: A party can switch fuel types mid-journey to transition between road networks. This requires a Finesse roll. On success, the transition is smooth. On failure, the party enters a junction that connects to both networks and must choose a direction with incomplete information. Switching fuel also resets the clock to 4 (partial refuel) rather than 6.

5. Character Archetypes

The Beeswax Surveyor

You have mapped 200 miles of commercial road and you know every milestone, shortcut, and seasonal variation on your assigned routes. You are reliable, professional, and slightly bored. The phosphor roads interest you because they represent the first genuinely new mapping challenge in a decade. You are also worried, because the phosphor roads suggest that everything you have mapped so far is the surface layer of something much larger.

• Drive: “Map the phosphor network before someone with less caution and more ambition does it wrong.”
• Approach Distribution: Force 1 | Finesse 3 | Mind 2 | Presence 2

The Tallow Historian

You specialize in tallow roads, which means you spend your time walking through places that the visible world has forgotten. You have found abandoned towns with food still warm on the table, libraries with books that do not exist in any surface collection, and roads that end at the edge of events that have not happened yet. You document everything. Your reports make the Guild uncomfortable.

• Drive: “Understand why the tallow roads preserve what the surface world discards.”
• Approach Distribution: Force 1 | Finesse 2 | Mind 3 | Presence 2

The Phosphor Courier

You carry messages and small cargo on the phosphor roads because they are the fastest routes in the network. You have seen the Roadkeepers. They left a light pattern at a junction you use regularly, and you have been leaving patterns in return. You are conducting unauthorized first contact with a civilization that maintains invisible roads, and you have not told the Guild because you are not sure the Guild would let you continue.

• Drive: “Learn what the Roadkeepers want before the Guild or the surface authorities decide for them.”
• Approach Distribution: Force 2 | Finesse 3 | Mind 1 | Presence 2

6. Starter Scenario & Why It Matters

The Convergence: Three Lantern Roads, one from each fuel type, have begun converging on the same location: an unmarked junction beneath a hill that, on the surface, contains nothing but grass and old stone. The beeswax road leads to a village that does not appear on any surface map. The tallow road leads to the village’s market, which has been trading with someone for decades. The phosphor road leads to the Roadkeepers’ nearest station, where lights have been blinking in a pattern the Cartographers have translated as “arrival expected.” Guildmaster Vael wants the junction sealed. Brenner and Sons want exclusive mapping rights. The Surface Authority wants the junction surveyed and reported. The Cartographers who discovered the convergence want to follow the phosphor road and meet whoever is waiting at the other end. The characters have enough fuel for one complete expedition. They must choose which road to follow, what to do when they arrive, and how to report what they find to factions that will use the information very differently.

Why It Matters: The Lantern Cartographers asks what happens when you discover that the world is larger than you mapped and that someone has been living in the margins. The Lantern Roads are not a hidden dimension. They are infrastructure: built, maintained, and used by people (or something like people) for purposes the surface world has never imagined. The characters are explorers in the oldest sense: people who walk into the unknown and come back with a report. The setting asks them to consider who the report is for and what happens to the unknown when the people in charge read it.
