I think we should make it where the old civs are dead and there tech is scattered, with records of there culture and what ever happened gone or extremely rare to the point where it would take a while to piece together the former history of the galaxy. If people want to keep there civs they can just have there race get contained back on there homeworld and be unaware of the events that happened. As for my plans Faust sees the events that unfold as a opportunity to bring back the Equestrians. She rebuilds Equiis and protects the Equestrian Races there, giving them magic and returning it to the universe once again. She also rebuilds Earth and preserves the Humans. While she guides the equestrians and makes sure they have some name and appearances to try to keep there history and development the same as before she does not do this for the humans Key, so you can change the entirety of human history. Faust will also preserve a few other races that I plan to use with my new Equestrian Empire app once we get the sequel out.
Faust will also make certain planets magical for the Equestrians to discover, they will contain powers and artifacts for the Equestrians to use.
