After King Sombra was banished from Equestria, his castle and servants appeared outside the borders, outside of all Equestrian law. An advertisement is found that he is looking for a caretaker for his castle, and Princess Celestia insists that Fluttershy go out to apply for the position. After her success with Discord, Princess Celestia was sure Fluttershy could turn King Sombra to good with her friendship.
But, Discord and King Sombra are different ponies, and Fluttershy is all alone...
They're like kind of humans, with hands feet and clothes. But still ponies, with wings, horns, fur, tails. I believe that's anthro, but I don't know for sure.
Rated for later clop and such.
