Sequel to The Crystal Prep Files

After finally returning to Equestria, Sunset Shimmer accepts Starlight's challenge and face off in a magical duel. What's the worst that could happen?

*Taking place during and after the events of Legend of Everfree*

A month has passed since the Friendship Games. Old stigmas are finally breaking down at Crystal Prep but Sunny Flare isn't convinced that these current events are natural. Naturally, she decides to investigate herself.
But upon certain discoveries that she and eventually the rest of her friends uproot, they realize they may have bit off more than they could chew. However, they do happen to know two people who they consider "magical experts".

Edit: I know this is late but I can't believe this story actually got featured. Thank you very much!

Having learned much about Equestria from both Twilight Sparkle and Sunset Shimmer, the two principals from CHS have always been curious about what the world is really like. Luna finally proposes the idea that the two should find out themselves just what its like to be a pony...and not just any pony but royalty as well. What could possibly go wrong in this situation?

Twilight could probably name about thirty of them.

This story is a sequel to Hello From The Other Side

Twilight Sparkle, Princess of Friendship, has had a lot on her plate recently. Even when she's not busy and even though she has Sunset to keep her company now, she still feels the need to get away from Equestria for awhile.

Twilight Sparkle, current student of Canterlot High, has been wanting for a long time to see Equestria for herself, to understand the origins of her powers.
Surely there must be a way for them to both get what they want. What's the worst that could happen?

Better yet, what's gonna happen between Luna and Rainbow Dash?

Something feels familiar about all this...
