THE NAME
Markers for the journey
On a mountain trail, a cairn is a pile of stones hikers build for whoever comes next. A young player's development works the same way: small stones, kept together over years, that show where they've been and where to go next.
Built by many, for the next traveler.
Every cairn starts with a few stones that someone chose to set down.
Four layers, one pile
AI reads the whole pile and points to one next step.
