create a miniature thread from your story. To add context, I mean a small choice that you make that then brings you to a little bit of text that brings you back to the story (A-B-C-A) instead of (A-B-A)

Note that you don't actually need a Codex or any Item to make this work, you can do it all through Links as well.
