What is this
Pope Innocent VIII is dead.
Conclave 1492 is a 40-person negotiation exercise set during the papal election of 1492, the most complex, high-stakes political event of the Renaissance. Play an ambitious cardinal, a mighty king, a daring queen, or a lowly Vatican functionary. You'll arrive with allies, rivals, secrets, and leverage, but so will everyone else. Over four afternoons, you'll scheme, bargain, cross, double-cross, and occasionally pray for salvation. And halfway through, one of you will be crowned Pope. If you aspire to be the next Borgia, Medici, or Ferdinand of Aragon — or if you aspire to defeat them — this is your training ground. Negotiate the future of the world.
Most of the characters are closely based on real historical figures, actual people who lived through the events of 1492, with resources, relationships, and goals drawn from the historical record. But some characters and some issues have been moved around in time, to fill the room with the most interesting people and put all the most important tensions on the table. For example, some of the cardinals in our game didn’t become cardinals until after 1492, and some issues are up for debate early. This is an alternate history, not a reconstruction.
The simulation has previously been run as the capstone of a university negotiation course. It was, by all accounts, an insane amount of fun. Now we want to bring it to Lighthaven, for anyone who wants to find out what they're actually capable of when Fortune's wheel is turning.

Who you'll play
Every character has secrets. Most of them have enemies.
All ~40 player characters are closely connected. Some of you are relatives by blood or marriage. Some of you went to seminary together — the same lectures, the same taverns, the same questionable parts of the city at questionable hours of the night. Some of your families have been trying to destroy each other for two hundred years. Characters fall into three groups:
Cardinals
The majority of players. Assembled here to represent every corner of Christendom, drawn from every walk of life: scholars, monks, crusaders, mercenary captains. Cousins of kings, scions of great banking families, and sons of dirt-poor farmers. Italians alongside Frenchmen and Spaniards. You have one vote in the conclave. Use it wisely.
Vatican Functionaries
A small group who run the machinery of the election: counting ballots, managing the sealed chamber, enforcing the rules of the conclave. Your office is neutral. Are you?
Outside Powers
Seven players represent the great secular powers of Europe: three kings, three queens, and one Roman mob. You cannot vote, but you can threaten, promise, and scheme from the outside, influencing the conclave through whatever channels you can establish.
Character assignments are made by the organizers before the event begins, based on each player's stated preferences and interests.
How it works
A crash course in negotiation. Then one of history's greatest negotiations.
The event runs across four sessions at Lighthaven: June 8–11, 3:30–6:30pm each day. Each session is three hours of unstructured negotiation — move through Lighthaven's rooms and corridors, pass notes, broker deals, find your allies, avoid your enemies. Just you and thirty-nine other people with competing interests and incomplete information. Before a pope is elected, the functionaries run three rounds of voting per session; after, the new pontiff fields petitions from everyone who wants something.
Optional Pre-Event · June 7 or 8
Negotiation Crash Course
A short, fun warm-up session covering skills and tactics that will serve you in the conclave. Not required, but players who enter with some training will get considerably more out of the experience. Practice exercises also help the organizers get a feel for each player's style, which may inform character assignments. Highly recommended if you can make it. Note your interest and we'll confirm when the time and place are known (will likely be June 7 or the morning of June 8).
Sessions 1–2 · June 8–9, 3:30–6:30pm
The Conclave
The main event. A main building serves as the Sistine Chapel, sealed for cardinals and functionaries, with the basement and tunnels designated for functionaries only. The Outside Powers convene in a separate location, influencing the conclave by whatever means they can arrange. Rounds of negotiation and voting proceed until one cardinal is elected pope, crowned, and besieged with petitions.
Sessions 3–4 · June 10–11, 3:30–6:30pm
The Aftermath
The great powers of Europe go to war. Then two sessions of post-war diplomacy as we redraw the map of Europe — a chance to secure, or recover, everything the election put into play.

Why 1492
The pivot point of the modern world.
It is July 25, 1492. The papal throne is empty. The cardinals are gathering. And the world outside the Sistine Chapel is moving faster than anyone yet understands. The election of this pope will be different, for it happens at the exact hinge between the medieval and modern worlds. Every one of the forces below is already in motion.
~1450
The Printing Press
Forty years ago, Gutenberg's press was set loose on an unsuspecting world. The Church's monopoly on written knowledge is already cracking. Bibles, pamphlets, heresies, and vulgar poetry can now be copied faster than any inquisitor can audit or burn them. Books that would once have cost as much as a manor house now cost merely as much as a man's fine coat. Nobody yet knows what this means. But they will soon.
1453
The Fall of Constantinople
The Ottoman Sultan Mehmed II took the city thirty-nine years ago, ending a thousand years of the Eastern Roman Empire. Greek scholars fled west into Italy, carrying manuscripts of Plato and Aristotle that no one in Europe had read for centuries. The Renaissance caught fire.
1480
The Ottomans
Twelve years ago, Ottoman forces landed at Otranto in southern Italy, burned its houses, slaughtered 12,000 of its people, enslaved 5,000 more, and held the city for nearly a year before being driven out. Christendom has not forgotten. But Mehmed II died in 1481; Sultan Bayezid II now rules, after defeating his half-brother Cem in a civil war. What manner of man is he?
December 1488
When Will Portugal Reach India?
For decades, Portugal has been feeling its way south and east around Africa. In 1488, Bartolomeu Dias rounded the Cape of Good Hope and confirmed that the coast turns northeast, toward India. The route exists. When Portuguese ships reach the Indian spice markets, they will cut out every Arab, Persian, and Venetian middleman who has grown rich on the trade for centuries. The age of exploration is not a distant dream. It is on the horizon.

The Reconquista Ends
After 780 years, the last Muslim emirate in Iberia surrendered to Ferdinand and Isabella. Granada fell to cannon and siege, gunpowder finishing what zeal could not. Spain is powerful, Catholic, and immensely ambitious. But it is not unified, not yet. Ferdinand rules Aragon; Isabella rules Castile. Spain, as a single kingdom, does not yet quite exist.
March 31, 1492 · Four months ago
The Expulsion of the Jews
Ferdinand and Isabella signed the Alhambra Decree. Between 40,000 and 100,000 Jews have been expelled from Spain. Many are still on the road. Sultan Bayezid, recognizing an opportunity, dispatched his navy to bring them to Ottoman lands. Spain is losing skilled workers, scholars, and doctors. The sultan is gaining them. "It is said that King Ferdinand is a clever man," the sultan reportedly remarked, "but by driving the Jews from his own country, he is impoverishing his empire and enriching mine."

Columbus Has Sailed
A Genoese navigator named Cristoforo Colombo departed Palos de la Frontera nine days ago with three ships and a theory. He believes he can reach Asia by sailing west, because the ocean cannot possibly be that wide. Most experts think he is wrong about the distance. Portugal rejected him; they have their own route. Ferdinand and Isabella, flush from the Reconquista, gave him the ships almost as an afterthought.
Right Now
Neither Holy Nor Roman
Maximilian I is the new Holy Roman Emperor, and waiting to be crowned by the new Pope. In theory his empire is sovereign over the kings of Europe. In practice it is a fractured patchwork of German princes who resist every attempt at central authority. For four hundred years the emperors and the popes have fought over who holds temporal power in the Christian world, a struggle that has torn Italy in half. That struggle is not over.
Right Now
The House of Valois
Since 1454, the Peace of Lodi has kept Italy's five great powers in an uneasy but functional balance. It is held together by constant diplomacy, mutual suspicion, and the occasional carefully chosen war. It is also about to end. Charles VIII of France is twenty-two years old, ambitious, and possessed of dynastic claims on Naples. If he marches south — and many believe he will — he will discover that Italy is rich, beautiful... and divided. The cardinals choosing the next pope are also choosing how Italy will meet the French king.
Ongoing
The Medici & the Banks
Florence has been the beating heart of the Renaissance under the Medici, patrons of Botticelli, Michelangelo, Leonardo; bankers to popes and kings; and protectors of more than one dangerous mind. Other banking dynasties, like the Fuggers of Augsburg, are rising around Europe. Enormous wealth is flowing into the hands of men whose loyalty is split between their duty, their faith, and their ledgers. The College of Cardinals you are joining has noticed, and so has everyone else.

Is Man's Nature Fixed or Variable?
When Constantinople fell in 1453, Greek scholars fled west with manuscripts no one in Europe had read for centuries. A generation of new thinkers went back to the original sources, read Plato in Greek, and started to ask what had actually been written. In 1486, a twenty-three year old named Pico della Mirandola proposed nine hundred theses for public debate in Rome, with an introduction called Oration on the Dignity of Man, arguing that humanity alone among God's creatures has no fixed place in creation, free to become whatever it wills. Pope Innocent VIII called it heresy and had him arrested. The same impulse to go back to the sources and strip away the glosses may eventually be applied to the Bible itself, with consequences no one in this room is prepared for.

Cracks in the Foundations
Martin Luther is just nine years old. But the friar Savonarola is preaching hellfire from the pulpit of Florence cathedral right now. He is prophesying the Church's ruin, drawing crowds so large they spill into the square. He is radical but he is not entirely wrong. The selling of indulgences, the buying of offices, the popes with their mistresses and their armies. The pressure that has been building for generations is beginning to find the cracks.
Right Now
The Prince
Niccolò Machiavelli is twenty-three years old, working as a clerk for a Florentine banker; invisible to history, but watching everything. He has grown up watching the Medici rule Florence with silk gloves over iron fists, watching kings and princes maneuver for advantage in the name of virtue, watching princes of the Church buy votes, trade titles, and threaten enemies in the name of God. He is forming a question that no one in his world has yet had the audacity to ask aloud: what if power has always worked this way — and what if it always will?
Why participate
What you'll actually get out of it.
This event is unusual in that it works on two levels simultaneously.
As a historical experience: By the end of the simulation, you will have an intimate, lived understanding of the political geography of late-15th-century Europe: the factions, the stakes, the personalities, and the forces that made 1492 the year it was. This is not like learning from a book or lecture. It is something closer to memory.
As a negotiation exercise: Most negotiation training uses simplified two-party scenarios. Conclave 1492 does not. Real political negotiations involve dozens of parties, shifting alliances, incomplete information, and interests that cannot simply be split down the middle. It is genuinely hard, genuinely fun, and a rare opportunity to try strategies you would never risk when the stakes are real. Pilots train in simulators so that when the emergency comes, it isn't the first time they've faced it. The conclave is the same.
Past participants have described it as one of the most memorable experiences of their lives. We believe the Lighthaven community is exactly the right audience.
From the organizer
A note on where this came from.
In 2024, I ran this simulation as the final exercise for my university negotiation course. I reached out to historian and sci-fi author Ada Palmer, who developed Temptemus Papam, a massive papal election simulation at UChicago she created to teach Renaissance history. I got her materials and advice, and adapted the simulation down to 40 player characters, shifting the emphasis from historical literacy to negotiation and coalition-building.
The result was extraordinary. Students who had spent a semester studying negotiation theory encountered something that no case study or exercise had given them before: the genuine chaos and creativity of high-stakes politics among dozens of parties with incommensurable interests. Students got so invested in their papal election roles that after class ended, they got back on the Discord server and continued to argue for hours about who owed whom hundreds of thousands of florins. It got so bad I made a #pointless-bickering channel and forced them to move all their fighting there. Here's what students said afterward:
Lighthaven feels like the natural next home for this simulation. It easily hosts a group of 40 people across buildings, basements, secret chambers, and catacombs. Anyone who's spent time there will immediately understand why it works.
