The premise
The Calvertan Republic collapsed eighteen years ago and never came back. What was left of Porto Calvera carved into three estates without anybody declaring it. The Vasilakis took the Kydon docks because their fathers had run them for a century. The Dragani took Velona Heights because it suited their particular genius for what is moved at night. The Caravello kept the bank because nobody else could read the ledgers. Between the three of them, the Exchange opened in The Arcade. A neutral clearinghouse for information, money, and favors that did not fit anywhere else. Anyone could use it. Nobody had to shake hands.
Four days ago, the Exchange's longtime operator was shot twice on Basin Boulevard. He was alive long enough to leave instructions. The instructions named you.
You inherit the ledger, the safe, the small office on the second floor of The Arcade, and the target on his back. The mainland is moving again. A Provisional Council from somewhere upcountry has arrived under the cover of clearing the spectre mines that have begun to wake in the abandoned Calvertan Quay. The Vasilakis and the Dragani have signed a truce neither of them believes in. The Caravello are quietly funding the Council. Father Konstantinos at St. Nikodemos says nothing in his sermons, which is its own statement.
There is a way to keep the Exchange alive. There is a way to take a side and burn the rest. There is a way to read the ledger your predecessor was killed for and decide for yourself which page he was on.
What this world plays like
Your first ten turns are spent reading the ledger and deciding which appointment your predecessor was about to keep when he was shot. You will meet Adrastos Vasilakis at his offices on the Kydon if you have something to offer him; he speaks slowly and in parables and will not raise his voice. You will meet Jelena Dragani only if you go to Velona Heights, and only on her terms. Lucien Caravello will send for you when he wants to.
By turn fifty, the safe has cash in three currencies you have begun to track separately, a list of debts owed to the Exchange that you can call in or sit on, and at least one envelope you have not opened. Standing with each family exists as a real number. The Provisional Council has begun to ask, politely, whether the Exchange might cooperate. The Basin Accord between Vasilakis and Dragani is fraying. Someone has tested the door of your office at three in the morning and left without trying further.
By turn one hundred, the campaign you are running is your own. You may be brokering a city-wide peace through the Exchange's neutrality. You may be quietly arming one family against the others. You may have struck a deal with the Council that the Caravello do not yet know about. The mines are still in the Quay. The mainland is still coming. The ledger remembers every payment. So does the bank.
Porto Calvera does not reset between sessions. Close the tab on Tuesday. Adrastos Vasilakis is still waiting for the answer you owed him.
Factions in motion
The Vasilakis Hegemony
The old power of Porto Calvera, controlling all licit trade through the Kydon docks. Led by the deeply traditional Adrastos Vasilakis, they present a veneer of legitimacy and piety, enforcing their will through established networks and brutal, old-world honor.
The Dragani Syndicate
Ambitious and ruthless newcomers who dominate the city's smuggling rackets from the paranoid hills of Velona Heights. Led by the cunning widow Jelena Dragani, they leverage fear, modern methods, and control over scarce goods to challenge the Vasilakis' dominance.
The Caravello Bank
The indispensable financial heart of Porto Calvera, operating with quiet, lethal neutrality from the commercial Arcade. Lucien Caravello and his tight-knit clan of Maltese and Sicilian bankers facilitate and launder every major transaction in the city, making them the silent kingmakers.
The See of St. Nikodemos
The moral and spiritual center of the city, based in the neutral territory of the Basin. Father Kyrillos attempts to minister to all, offering sanctuary and mediating minor disputes, but his influence is waning against the rising tide of secular pragmatism and violence.
The Provisional Council Representatives
A clandestine cell of agents representing the foreign interests that secretly engineered the Republic's collapse. Operating from the shadows, they seek to manipulate the city's factions and destabilize the current balance of power to install a new, more compliant regime.

Places that matter
The Kydon
The sprawling, chaotic heart of Porto Calvera's port. The air smells of diesel, salt, and grilled fish. The noise of ship horns, rattling cranes, and shouting men is constant from dawn to dusk. White-plastered tavernas and apartment blocks crowd the narrow streets leading from the container yards.
Velona Heights
A hillside district of respectable-looking villas and new apartment buildings overlooking the port. The streets are clean, the gardens are manicured, and an unnerving quiet prevails. From the Dragani mansion at the crest of the hill, every street below can be observed.
The Arcade
The old commercial heart of the pre-Collapse city, now a canyon of stone-faced banks and money-changing houses. Men in suits speak in hushed tones in cafes, exchanging documents in sealed envelopes. The Caravello Bank, a former Republic Treasury building, dominates the central plaza with its bronze doors.
The Basin
The flat, low-lying old city center, a maze of alleys and small squares. The Basin is a chaotic neutral zone where the territories of the three families meet. It houses the city's only real hospital, the Orthodox Cathedral of St. Nikodemos, and the narrow, unassuming building of the Exchange.
Calvertan Quay
The skeletal remains of the old Republic ferry terminal that once connected Porto Calvera to the mainland. Rusting gantries stand silhouetted against the sea, and the terminal building is a hollowed-out shell of broken glass and graffiti. The wind whistles through empty waiting halls and ticket offices.
A real turn from this world
The bell on the door is broken so you hear the man before you see him. He puts a small cloth bundle on your desk and does not sit. You do not ask him to.
"From Velona," he says.
You weigh the bundle. Foreign coin. Dragani's preferred currency for things she does not want recorded in the bank's ledger. You make a note. The note is in your handwriting now, not your predecessor's. You write the date. You write the source. You do not write what it is for, because the man does not say.
He waits another moment. He nods once. He leaves.
Coffers update: +220 (mixed foreign, unrecorded). Standing with Dragani Syndicate: +1. The Exchange's ledger now shows a debt you owe Velona, payable in a favor of Jelena's choosing. The world remembers.
Why Porto Calvera - The Exchange holds up over a long campaign
Most AI roleplay tools are built around a single session. They start to fall apart at hour ten and are barely playable at hour fifty. Porto Calvera - The Exchange doesn't, because the world isn't living in a chat history - it's living in a database.
Mechanical truth in Postgres. Coins, inventory, NPCs, factions, locations, properties - all in real database rows. The narrator describes around the database; the database is what's true. By turn 500, your business ledger still balances and your apprentices still have the names you gave them.
Hierarchical chapter compression. Every chapter compresses into a tight summary; summaries compress into act-level summaries. The hundredth turn can pull a relevant detail from chapter two without flooding the context window.
Semantic memory. Important moments are embedded as vectors. When the current scene references an old promise, the engine retrieves the exact exchange where that promise was made - even 800 turns ago.
