In the quickstart the Creating New Character move looks like it's about to copy the text from the Write Your Epilogue move but then cuts off mid sentence. I'm assuming this is an error and that we're supposed to make new characters as we play. Any guidance? 

I have not written this move yet!

The idea though, would be that it's a way to continue playing within the world that you have established when your original character is forced to or chooses to leave the story in some way. You would choose some elements relevant to the departing character and retain them... Vows and/or Assets, mainly. It is gonna be pretty rules light, and you might be able to intuit a lot of what it is going to say just from the context.

I will have full text for this move in the upcoming update!
