Derby at the End of Time

“My name is Cass Rivel. I was born in 2089. My co-driver was born in 1847. Our mechanic is from an era that no longer exists because we raced through it wrong. The last track was the Colosseum circuit, and I accidentally taught a Roman senator the word ‘aerodynamics.’ Timeline Integrity dropped by two. The Authority is not happy.”

1. Setting Overview & Tone

The Great Temporal Derby was established by the Chrono Authority after the Fracture: an event that shattered the timeline into competing versions of history that are slowly collapsing into each other. The races are not entertainment. They are repair missions disguised as competition, because the Authority discovered that the act of racing through a fractured era at high speed, following precise routes that trace the fracture lines, is the most effective method of stabilizing temporal damage.

Tone: Fast, chaotic, and laced with the specific absurdity of trying to maintain historical accuracy while driving a machine through someone else’s century. The setting is an adventure comedy about people who are responsible for the integrity of history and who are also racing each other, which creates priorities that do not always align.

Sensory Pillars:

1. Sight: The Temporal Gates: shimmering portals between eras that drivers pass through at speed, the landscape changing from neon future to gaslit Victorian to sun-baked ancient in the space of a hairpin turn. The vehicles: custom machines built from components sourced across multiple eras, powered by temporal displacement engines that leave a trail of chronometric shimmer. The eras themselves: historically accurate landscapes interrupted by the presence of high-speed vehicles, which is disorienting for the drivers and apparently invisible to the local population (the Authority’s field dampeners handle that, most of the time).
2. Sound: The roar of temporal displacement engines, which sounds different in each era because the acoustic properties of the air change with the timeline. The pop of a Temporal Gate opening, which is the sound of two eras meeting. The Authority’s radio channel, crackling with instructions, warnings, and the specific frustration of a mission controller watching drivers treat a repair mission as a competition.
3. Touch & Smell: The vibration of the vehicle at temporal transition, which feels like the car is briefly existing in two places at once. The smell of each era as the driver passes through: wood smoke and animals in ancient periods, coal and metal in industrial ones, ozone and polymer in future ones. The heat of the engine, which runs hotter as Timeline Integrity drops because the temporal displacement system works harder in unstable conditions.

2. The Eras

The Colosseum Circuit runs through ancient Rome, threading through the forum, around the Colosseum, and along the aqueducts. Historical hazards include chariot traffic, military parades, and the occasional gladiatorial match spilling into the streets. The circuit repairs a fracture caused by an unauthorized time traveler who introduced firearms to the Roman military. The damage has been mostly contained, but the Praetorian Guard’s uniforms show subtle design changes that the Authority is still correcting.

The Ironworks Track passes through 1840s Manchester during the industrial revolution. The course follows factory roads, canal paths, and railway viaducts. Hazards include steam, coal dust, and the dense urban traffic of a city that was not designed for high-speed anything. The fracture here was caused by a future medical textbook that appeared in a bookshop in 1842. The track’s route traces the distribution path of the information.

The Neon Meridian is a circuit in a far-future megacity (estimated era: 2340). The track runs through vertical urban canyons, across sky-bridges, and through a commercial district where the advertising displays react to the drivers’ vehicles. The fracture in this era is different: information from the past is leaking forward, and the city’s historical records are being altered by events that have not happened yet.

The Authority Paddock is the between-races staging area: a temporal bubble that exists outside any specific era, where drivers maintain their vehicles, receive briefings, and argue about race results. The Paddock has the sterile, temporary feel of a space that does not belong to any time, furnished with equipment from multiple eras because the supply chain is chronologically complicated.

3. Factions

The Chrono Authority manages the Derby and the timeline repair effort. Director Sable Cross runs the operation with military precision and the specific patience required to manage drivers who treat temporal physics as a suggestion. Cross’s priority is Integrity. The drivers’ priority is winning. These priorities conflict regularly.

The Racing Teams are small crews of displaced individuals: drivers, navigators, and mechanics sourced from different eras and partnered based on complementary skills. Team Rivel (Cass Rivel, driver from 2089, and her navigator Elias March from 1847) is the most successful and the most disruptive. They win races and damage timelines with equal enthusiasm.

The Era Locals are the historical populations of the eras the Derby races through. They are not supposed to notice the race (field dampeners handle visibility), but the dampeners are imperfect. A Roman merchant who sees a shimmer in the air, a Victorian factory worker who finds a tire track in the cobblestones, an industrial-era child who picks up a dropped component, all of these are minor integrity violations that the Authority must clean up after each race.

The Fracture Agents are individuals who deliberately caused the timeline damage. Some are time travelers who made mistakes. Others are intentional saboteurs who benefit from timeline instability. The most wanted agent, known only as Palindrome, has been seeding anachronisms across multiple eras in a pattern that the Authority has not been able to decode.

4. Unique Mechanic: Timeline Integrity

Track a shared Timeline Integrity from 0 to 6, starting at 4.

Raising Integrity (+1 each):

• Complete a race without causing anachronisms
• Successfully repair a fracture point during a race
• Remove an anachronism from an era (recovering dropped technology, correcting altered records)
• Capture or neutralize a Fracture Agent

Lowering Integrity (-1 each):

• Cause an anachronism (use future tech visibly, interact with a historical figure, leave modern debris)
• Fail to complete the race route (missing a fracture point leaves it unrepaired)
• Allow a Fracture Agent to seed a new anachronism
• Era bleed (when a race causes elements from one era to appear in another)

5. Character Archetypes

The Time-Displaced Driver

You were pulled from your era by the Chrono Authority and given a choice: race or be returned to a timeline that may no longer exist. You chose to race. You are fast, reckless, and increasingly confused by the eras you drive through, because you were born in one century and you are living in all of them. Your driving is excellent. Your historical sensitivity is poor.

• Drive: “Win enough races to earn the Authority’s trust, then use that trust to find out whether my original era still exists.”
• Approach Distribution: Force 2 | Finesse 3 | Mind 1 | Presence 2

The Historical Navigator

You were born in 1847 and you navigate for a driver from 2089. You are responsible for route planning, historical hazard awareness, and preventing your partner from doing things like teaching Roman senators modern vocabulary. You are meticulous, knowledgeable, and perpetually exhausted by a partner who treats the past as a racetrack rather than a responsibility.

• Drive: “Keep the eras intact long enough for the Authority to repair the Fracture, and ensure that the racing does not cause more damage than the original break.”
• Approach Distribution: Force 1 | Finesse 1 | Mind 4 | Presence 2

The Authority Controller

You sit in the Paddock and monitor Timeline Integrity in real time. You give instructions to drivers who do not listen, track anachronisms that should not exist, and file reports that describe events no sane bureaucracy would believe. You are the person who decides which fractures are prioritized, which means you are the person who decides which eras get repaired and which ones wait. The weight of that decision is significant.

• Drive: “Maintain Integrity long enough to repair the major fractures, and figure out what Palindrome is building with all those seeded anachronisms.”
• Approach Distribution: Force 1 | Finesse 2 | Mind 3 | Presence 2

6. Starter Scenario & Why It Matters

The Palindrome Pattern: Three races across three eras have revealed that Palindrome’s anachronisms form a pattern: each one is placed at a point where a significant historical decision was made, and each one subtly alters the outcome. The Authority has identified the next target: a race through revolutionary-era France, 1789, where Palindrome has planted something at the National Assembly. The race must trace the fracture line through Paris during the revolution, repair the damage, and locate Palindrome’s device, all without being seen by a population that is already suspicious of everything. Team Rivel is the fastest team. They are also the most likely to cause an anachronism. The Authority must decide whether speed or caution is more important. The drivers must decide whether winning the race or completing the repair is the priority.

Why It Matters: Derby at the End of Time asks what we owe the past and whether we can be trusted with it. The drivers are racing through history in machines that should not exist, repairing damage that was caused by people who treated the timeline as a resource rather than a responsibility. The setting is about stewardship, competition, and the specific tension between doing the job right and doing it fast.
