A reader writes to ask:

My question is in regards to formatting a prologue. My story is a fantasy/sci-fi tale that has two separate events that occur to two separate groups that lay the foundation for the actual "chapter 1" of my tale.

In my manuscript, I want them to be the prologue/precursor to my story, but I am unsure as to what the correct formatting rule would be (if there is one) in connecting the two. Do I just add an extra space and start the new scene or do I need to add a new heading of some sort?

There is no rule about headers for new scenes in fiction. The standard thing to do in your scenario would be to just skip a line and start the new scene—we call this a "scene break" or a "line break"—but really you can do whatever you want. You could label the two scenes "1." and "2." within the prologue if you wanted, or you could treat each like a separate prologue and call them "Prologue A" and "Prologue B." You don't even need to call the prologue a prologue if you don't want to. You could simply label it "Earlier" or "1987" or "February" or "Bob Jones." Or you could give it no label at all.

If you go to the bookstore or your own bookshelf and start flipping through novels at random, I'm sure you'll see all those methods, and more. The point is, it's your book and you can call your chapters and scenes what you like, if you like. Whatever you think works best for your story.
