Sequel to One Night with Celestia

I have been pondering recently about a possible sequel to One Night with Celestia now that I have finished with that story. If I were to write a sequel, it would be its own story, rather than I just keep tacking chapters onto the end of One Night with Celestia.

I have a couple of ideas and have even written down a rough outline, but as of now, I do not know what direction I want to take the story in. I already have an idea for the first chapter, but after that, it's all up in the air.
