Book 3 - Link Actions
Chapter 1 - Link
Understand "link [something] to [something]" as linking it to.
Linking it to is an action applying to two things.
Carry out linking it to:
now the noun protects blank;
now the second noun protects blank;
now the noun affects the second noun;
now the second noun affects the noun;
Report linking it to:
say "You build a mutually-effective link between [the noun] and [the second noun].".
Linking something to something is labor.
