Hello!
I don't think you could literally combine Fable Maker with your game. But, I'd be happy to give some advice on how I set up my engine to maybe help you out. If you don't need all of the fancy effects, it should be very easy to set up. You can store your story in a JSON file or an Array ( A comma seperated value file). It depends on how you set up your game to read your story. Fable Maker saves story lines in a numbered order, so the game reads each line in order. For example,
1: "hello"
2: "This is an example"
3: "Of how stories are stored in Fable Maker"
I hope that made sense. I'm happy to help if you have any other questions.
