Three is what came before you and what you came from. The shape of your house, the names you didn't pick, the people who shaped your spine. Nobody walks out of three alone.
Six is the watch. The middle gate. The part where you start to see the system that's been seeing you. Most people stall here and call it adulthood.
Nine is when the watcher becomes a maker. You stop describing the weather and start changing it. The Society moves through all three.
