Have you ever wondered what tribal life might have been like if humans co-existed with dinosaurs? Wanted to lead a hunt against a pack of theropods, or conduct shamanic rites for the wellbeing of the tribe? Hunt dinosaurs, explore a strange prehistoric planet, build bonds with neighboring tribes and more in a richly detailed dino-dominated world!

The Setting

On one side of a young planet, a supercontinent dominates the world ocean. The large thumb of land extends from the southern pole and stretches high to the northern latitudes, ending in the northern sea. Down it's length a great scar extends almost from coast to pole, an enormous canyon splitting the continent in two where tectonic forces wrestle in the planet's mantle. A majestic planetary ring extends across the sky at the equator, allowing easy navigational reference for all cultures. Also in the skies are two moons, one emitting a ghostly green light and the other so pocked and cratered that it's surface resembles a hand. The planet breathes new life at the recession of the ice age, but the cold dark lingers in the living memory of its paleolithic peoples...

The North

Hundreds of miles of sandy desert isolate the north from the rest of the continent. Between it and the northern sea, however, a lush river delta dominates, fed from a grand river draining from the great canyon. The peoples and cultures of this region are influenced by Arabian cultures.

The East

Hills leading into mountains into volcanic crags characterizes the east. Off the coast, silhouetted on the horizon, a giant supervolcano smokes ominously. The peoples and cultures of this region are influenced by the Aboriginal cultures of Australia.

The South

The south remembers the ice age perhaps best of all, still locked in the icy grip of a titanic glacial shelf despite it's slow retreat. Deciduous and boreal forests, taiga and permafrost characterize this region. The peoples and cultures of this region are influenced by the Innuit of northern Canada.

The West

Choking jungles and foggy rainforests make travel especially hard in this region. The venomous animals and threats of disease also hide a mysterious civilization on the rise... The peoples and cultures of this region are influenced by Meso and Central America.

The Center

The center of the continent is carpeted with prairie, wild maize, and arid deserts. The great canyon houses many of the cultures here, the river cutting through the rock providing sustenance for all life. The peoples and cultures here are influenced by Native American cultures.

Dinosaurs

They're the dominant form of life on this planet, and an ever present danger. In some cases, tribes have domesticated some species of dinosaurs, but in many cases they remain wild and savage. Tribal peoples of all cultures conceptualize dinosaur names as reflective of their appearance or (in the case of domesticated dinos) their function. However, since this is ultimately a game for your entertainment, the scientific names of any mentioned dinos should appear beside the first instance of a dino being named. In this way you can quickly copy and paste the scientific name into google and get a visual idea of the dinosaur in question, in addition to their narrative description.

Language and Trade

The continent is vast and many regions are isolated from the others, but with the receding ice age new trade routes have become available. Each region of the world speaks a common language, though dialects can exist within them. Peoples of different regions may have initial problems communicating, but with enough time and effort any language can be learned.

Each region has a good, or set of goods, valued by the others.

North: Saffron and salt.

East: Obsidian glass.

South: Tin and furs.

West: Cocoa.

Central: Maize.

The Moon Kingdom

A mysterious civilization rises in the jungles to the west. They carry bronze, a frightening advance in metallurgy, and espouse a formalized religion centered on the twin moons. Many tribes have only heard of them, but others have met their traders. Supremacist and isolationist, they are likely to remain mysterious for now...

Personal notes:

First off, I highly recommend you use a proxy for this bot. It has a lot going on, and a big context and logical horsepower will be beneficial. It was tested primarily on DeepSeek, which handled it mostly alright. Sometimes the LLM will forget how to format dialog because of the differing languages, and if you encounter this then you can use the following format to help encourage the LLM to correct itself:

If the language is your character's native tongue, it should appear normally "Like this."

If the language is unknown to your character, it should appear in non-English and in angled brackets <"Como esto">.

If the language is foreign but your character speaks it, it should appear in angled brackets and include the language or dialect <"Like this.">(Canyon Speak).

If you've bothered to read this far, then congratulations! You have the curious drive or attention span to learn about the ~secret options~. Which is to say, listen, LLMs will do whatever you want. I set up the initial message so that your character jives with the setting in the smoothest way possible. But if you want to be, say, a time traveler or a survivor of a spaceship wreck, then you can just start your initial message that way and the LLM will adapt. However, there might be some jankiness as tribals interact with higher technology levels or in how information is presented to you. Another common problem playing modern characters is that they will think of dinosaurs with the simple tribal naming scheme. Unfortunate, but that's ultimately why I cut these options from the initial message. If you don't mind editing bot responses or just living with the jank, then playing a modern character can be fun!

Proxy on and definitions open for you edification and modification!
