About This Game

Open Beta

Note that the game is still under active development. I think that there is enough to start letting players see what I've been working on, however I have lots of features that I'm still eager implement. My hope is that this game will gradually turn into a very complex ecosystem and generate some very interesting stories. 

Join me on Discord to let me know what you think I should be working on. My goal is to have regular updates every other week or so. 

Thank you for supporting independant developers. 

Premise

You arrive in a living medieval city on the cusp of a new century. Somewhere in its alleys and almshouses, older powers are moving.

Umbral Coterie is a dark, character-driven city simulation built on procedural generation and emergent storytelling. Every citizen — from the drunken thatcher to the cardinal's bastard son — has a name, a family, a faith, four humors balanced uneasily in their blood, and a daily routine that unfolds whether you watch or not. Befriend them. Bleed them. Bury them. The city remembers.

There are no scripted quests. There is only the city, the shadow it casts, and the consequences of standing in it.

Key Features

• A Living Medieval City: Hundreds of citizens with full personalities, occupations, relationships, faiths, and schedules. They wake, work, drink, pray, gossip, fall in love, fall ill, and die.

• Emergent Storytelling: No two playthroughs tell the same tale. Every marriage, murder, plague, and betrayal is generated from the simulation itself. The chronicle of your city is written as you play.

• Procedural Generation: Streets, families, bloodlines, and histories are forged anew each game. A different city. A different rot. A different ruin.

• Rivaling Factions: In addition to the forces of the church and the city, sinister forces move beneath the surface, and the deeper you look, the more they look back. Discover them on your own terms — or stumble into them at the worst possible moment.

• The Four Humors: Personality is not a stat sheet. Each soul is shaped by sanguine, choleric, melancholic, and phlegmatic humors, inherited from parents and shifted by trauma. Compatibility, ambition, and madness all emerge from the blood.

• Consequence That Lingers: Citizens remember. Families remember. The town's chronicle remembers. A sin committed in winter may not be repaid until a generation has died.

The Long Game

This is not a game about winning. It is about building a coterie that can rival existing powers and reach a place of honor. A bloodline. A legend.

Something is waiting.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Much of the code base is written with the assistance of AI, however only under the close control of the lead developers as control of the design is critical in making a good game. Bugs found in the game should be blamed on me, not AI.

All of the art is made by hand. In some cases, AI is used to create templates or patterns that are completely redone by hand. More common thinks like resizing or pixelating an image is done via conventional tools for pixel art development.

Mature Content Description

The developers describe the content like this:

There is no nudity or depictions of sexual acts at this time. I'm keeping this open as I develop and will update if this changes.

Because of the generally violent and erotic nature of vampire ethos, I have decided to mark this game as Mature.
