Chapter I · The Unwritten Path
Xyon is precise, patient, and possessive. He wrote one script for the world and made every choice obey it. You carry a rune that still accepts new lines. Begin with short lists of steps, then learn to choose an action each heartbeat. Ten missions stand between the ruins and his gate.
function decide(hero, world, memory) {
const enemy = hero.nearestEnemy();
if (enemy && hero.distanceTo(enemy) === 1) {
hero.attack(enemy);
} else {
hero.move("east");
}
}
The world calls your function once per decision. It obeys exactly one action, then asks again. No packages, no network, no ambient clock.
Xyon: “A branch is a debt. Every one of yours will be paid.”
Ten missions · one idea each
Every mission teaches one idea: a list of steps, their order, a decision that looks at the world, an array, and finally all of them in one program.

A preview never awards completion. A server run replays your commands through the authoritative core and sealed runs land in your Chronicle.
