where new ideas are bred
Choose two beings, or three, and a way of breeding them; see which organ each gives; then ask for candidates, the ideas that might emerge where those organs meet. Star them, choose one, and it is written into the codex, keyed under the four trees and drawn.
the first step
Choose two beings, in order; the order matters where one gives its kernel and the other carries it. Three or more for a system or a field.
the second step
Each operator takes something different from each parent.
