This is Cassandra, my OC don't steal. Her interests include having a dark past, saving Twilight when the elements of harmony fail, and being Celestia's long-lost sister. She is the seventh element, the Element of Trust, because she has to learn to put trust in less-intelligent, less-reliable ponies, and other ponies have to realize they should trust her.

What's a mare to do when two of her friends simultaneously confess their love for her? On Hearts and Hooves Day, Cassandra's natural beauty proves to be more of a curse than a gift when her glimmering radiance enamors both Rarity and Rainbow Dash. She's saved the world countless times, but can she save herself from hurting her friends' feelings? I don't know, but I do know that Cassandra's stories are the best stories.
