Worldview

Rome still calls itself a republic — but the bronze eagle has already begun to cast its shadow. In this grounded, cold and epic world, real power flows between legion commanders, senatorial nobles, grain contractors, and the crowd in the streets. There is no public magic here, only law, debt, blood, military merit, rumor, and assassination. Every election, every grain ship, every returning legion pushes Rome toward another fate.

The water of the Tiber reflects crimson cloaks — and the blood in the alleyways. Temples still smoke on the riverbank, but the drums of the border camps have already decided the capital’s destiny. The Republic speaks through law and citizen assemblies, yet wealth, armies, and personal prestige are tearing the old order apart; everyone claims to defend the Republic while fighting over the shape of the empire to come.

Characters (8)

They stand at opposite ends of the Republic’s fracture — and every one of them claims to be saving Rome. A young senator who trusts the law, a beloved general the Senate fears, a noble widow who rules the grain trade and its secrets, and a tribune who turns hunger into thunder. All covers were auto-generated by GPT Image 2.

Locations (13)

From the dust of the Forum to the frost of the frontier, Rome’s fate travels along its roads and grain ships. The Curia votes, the Subura riots, the granaries of the Aventine feed or starve the city, and beyond the Alps a cold outpost holds the door to Italy. Every location is a stage where power becomes visible.

Events (3)

The Border Pay Crisis
The northern legions go unpaid and their veterans’ land claims stay unresolved, letting Marcus’s personal prestige outrun the Senate’s commands.
The Ostia Grain Fleet Delay
A key shipment of grain fails to reach port, driving up bread prices, stirring the streets, and pointing suspicion at whoever pulls the strings behind the docks.
The Military Command Bill
Lucius pushes a bill to limit the tenure and entry rights of provincial commanders — a legal move that may only provoke the army into a harsher answer.

World Rules

No Public Magic
There is no open magic and no divine miracle — law, debt, blood, military merit, rumor, and assassination are the only forces that move events.
The Republic’s Shell
Rome still calls itself a republic, but wealth, armies, and personal prestige keep eroding the old order in the very name of preserving it.
Bread Rules the City
Grain ships, granaries, and grain prices are weapons sharper than any sword — feeding or starving Rome decides elections, riots, and allegiances.
Loyalty Outruns Law
A soldier’s loyalty to his commander can outpace the Senate’s authority; a general’s private prestige is a standing threat to the Republic.
Law Is a Battlefield
Statutes, vetoes, and imperium restrictions are fought over as fiercely as any siege — a single vote can be as deadly as a legion.

Studio Interior

World, Not Work

In Neta Studio, a world is the beginning of everything. A world contains characters, locations, events, factions, and rules — all generated by AI from a single sentence, all referenceable, rewritable, and expandable.

A world is not a game, a video or an image. A world is the source of all of these: from the same world, you can generate interactive adventures, web games, cinematic videos, and scene art — each inheriting the same worldview, the same conflict between law and legions.

World → Game

Select a storyline from world cards, AI auto-writes the plot and logic, generates art, and builds an interactive adventure like Hungry Harbor: Hidden Scales.

World → Video

Generate dynamic videos from world characters and scenes — location intros, the ten-place teaser, vertical character films.

World → Assets

Each character auto-generates a cover, each location auto-generates a background. The world itself is an asset library.
