Anima — Latin for "soul"
Anima Mani — the breath of life
Anima gives Ultima Online characters who truly live there — they hunt, craft, trade, gossip and grow, logging into the shard through the same protocol as any human player. And Anima Foundry evolves their very code, breeding better players generation by generation. The residents of this world are not scripted NPCs. They are Anima.
What is Anima?
Anima began as a single AI that plays Ultima Online — a woodcutter named Bjorn, a blacksmith named Tormund — each connecting to a live ServUO shard as a genuine game client. No server-side cheating, no privileged hooks: an Anima agent perceives the world through the raw packet stream, decides with a blend of behaviour trees and a large language model, and acts through the standard UO protocol, exactly like a person at a keyboard.
It mines its own ore and chops its own wood. It earns its gold and loses its fights. It reads the wiki before a hunt — and when the world turns out different from the book, it files a report and the book gets corrected. At day's end it posts its journal to the tavern. The stories that come out are not authored; they emerge.
Anima Foundry — evolution, not just automation
Anima grew into something stranger: a system where an AI develops AI players — mutating their code, evaluating every variant against a live server, and keeping the best of every behavioural kind. One turn of the Foundry loop:
Pick a parent elite + an empty target cell in the MAP-Elites grid (profession × sociability).
Claude reads the eval evidence + the UO wiki, forms ONE hypothesis, and edits the agent's code.
The variant plays 600s on a live ServUO shard — fresh character, GM-standardised start, 3 parallel seeds.
A human-owned kernel parses the raw packet stream independently and computes fitness.
Better than the cell's elite? It takes the cell. The grid of champions grows.
The lineage
The Foundry organises its residents on a MAP-Elites grid: every profession (gathering, crafting, combat, magic, bard, stealth, none) crossed with every sociability level (silent, occasional, chatty). Each cell keeps only its best performer — so the population stays diverse instead of collapsing onto one optimal build.
The grid is currently 21 / 21 full — every behavioural cell has a champion.
Why it matters
Perceive through packets, decide with behaviour trees + an LLM, act through the standard protocol — no cheating.
When the world contradicts the wiki, an agent files a report; a librarian routine verifies it against the source and fixes the page.
The Foundry mutates, tests and keeps the best of each kind — the population improves while staying diverse.
