A grounded world demonstration
A mine with a reason to exist.
Copperhollow is a gem-mining camp run by simulated miners with real beliefs, grudges, and pay demands. The new part is under their feet: the mine isn’t placed, it’s explained. A generated planet decided where the seam is, what it carries, and why — and you can ask.
The camp
You are the Overseer. Miners with individual temperaments work the faces of a seam, get injured, gossip in the tavern, refuse ground they’ve learned to fear, and renegotiate when a rich strike makes them bold. Gems go to auction; merchants bid; a quarterly taxman keeps score. Every one of those behaviours is simulated cognition — belief graphs, drives, trust — not scripted theatre.
Copperhollow has run for a while as a research camp for that substrate. This beta adds the question the whole Taniwha stack exists to answer.
The one idea
Ask why the mine is there.
In most game worlds the mine is where a designer clicked. In Copperhollow’s Site Survey, you select the mine, the seam, or the site itself, and the world answers with its chain of reasons — every step labelled with where it came from:
1
The rock
Granitic gneiss basement under a worn-down collision belt — a fossil orogen on rigid craton, far from any live plate boundary.
2
The granite
That setting is what makes fertile S-type granite. The world’s pluton gate reads the basement, the belt, the missing arc — and opens.
3
The pegmatite
One batholith in the fertile tail carries pegmatite dykes in its roof zone. The camp’s seam is one of them: a lithium–cesium–tantalum body, the gem motherlode class.
4
The gem
An LCT pegmatite rolls its species from its own seed — here, rubellite tourmaline. The camp sells it as Starfire Crystal; the page tells you that name is a costume.
5
The water
A spring rises at the site. The camp stands where the water is; the adit stands at the dyke. Nothing was placed by hand.
Walk the survey.
Click a marker or pick a feature, and read the ground’s answer — then change a condition and watch the seam die. Every value is read live from a Kano-generated planet; nothing here was written by hand.

Every step above carries one of four labels, so you always know what you’re looking at:
world fact — Read verbatim from the generated world’s records — rock, strata, tectonic history, the pegmatite body.
derived by the world’s rules — Computed by the world generator’s own siting functions, including every counterfactual.
staged — Presentation glue, and labelled as such — chiefly the fantasy mineral names over the real gem families.
replayed — Recorded from a reference run of the deterministic camp simulation — pick a day in the survey and watch the seam step change. In the running camp, this step is live.
The Overseer's office
A camp full of people.
The survey explains the ground. This is what stands on it: a roster of miners with their own temperaments, a crew formed around the seam, gossip moving through the tavern. Every one of them is simulated cognition — not scripted theatre — so the camp behaves like a place, not a diorama.
This is a recorded run of a young camp finding its feet — nobody wrote the story below. It hired steadily, kept its books in the black, and has just opened a second vein to grow into. Mining is dangerous work, so a few hands carry injuries — the crew earns its reputation on accidents survived. That is the simulation being honest, not a script being tidy.

Between minds and worlds.
Copperhollow sits where the two halves of Taniwha meet: minds shaped by experience, on ground shaped by history. The miners run on the same cognitive substrate as Briarwatch; the ground they stand on is generated by Kano. Follow either one down.
