This group is the place to explore and speculate about the back-story of Equestria.
What was life like before Equestria? What did the Hearth Warming Eve story gloss over? Where did the alicorns come from? What adventures did Star Swirl the Bearded have? What was Celestia's conflict with Nightmare Moon really like? What really happened during Discord's reign? How might G1-G3 ponies possibly fit into this history? These questions and many more are fair game.
Stories should take place in the past, or involve time travel to or from past eras, or reveal some significant secrets about past events (i.e. more than a mere mention or two in passing).
