If you’re writing speculative fiction, fantasy, or historical fiction, that means creating the rules of the world in which the action takes place, and solidifying not only what is and isn’t possible, but why. When you do, it’s comforting to remember that the one thing that remains constant is the human element—the emotional, psychological reality that underlies everything. That doesn’t change. You’re writing about how humans view the world whether that “human” consciousness is coming from WALL•E, a Brave Little Toaster, or Yoda.
