Tundra is Rarity and Sweetie Belle's cousin. She is visiting from the United Stables of Amareica. Maresota to be specific. This takes place after Magical mystery cure but before equestria girls, so Twi is an alicorn, but she still works in the library.

This is my first story so it is not very good. And it was something nagging me and i just wanted to let it out.
