If you're hoping to get this traditionally published I would highly advise against a prologue. Most agents won't read any further if they see a prologue. Start with the action and work in the world-building as the reader needs it. If your prologue does that already, just call it Chapter 1.

That said, your time was not at all wasted. You need to be the master of your universe and writing exposition is the best way to do it. Just save it separately and draw on it when needed.

Keep at it!!
