Combat that learns
A language model trains the NPCs to fight you. When you get better, they get better. The combat stops being something you can memorize.
— a world being written —
An MMORPG built by one engineer, on systems that refuse to repeat.
The machine is ready. The pen is yours.
— what is being built —
A language model trains the NPCs to fight you. When you get better, they get better. The combat stops being something you can memorize.
Every recipe is a chain of decisions. Every market has people on both sides of it. The economy is what the world is made of.
The merchants you stole from. The hunters you saved. The altars you found first. The world keeps the record.
— no installation —
Vellum has no client to download. Nothing to install. Open the site in any modern browser and you are in the world — your own PC, a friend's laptop, a library terminal, a demo machine in an electronics store. Sign in, and the world is there.
Pledge a token on your phone at lunch; play from a desktop that evening. Nothing follows you except what you have written.
— a note —
I did not start with a world. I started with a complaint. Every MMORPG I played went stale. Not because the developers were lazy — because the systems underneath them produced repetition.
I treated this as an engineering problem.

The NPCs remember the last three encounters they had with you.
week 47 · 2026-02-10
Three weeks of fluid simulation work; one altar moved by a pixel.
