The 7th element

I look around me and notice all of the town's Pony's are looking at me confused.  I  suppose they have a good reason to I mean this is there first time seeing a human after all I say in my head. Celestia's horn starts to glow so I look around to see if there's an aura around me. At first there's nothing and Celestia looks sad but then it begins to appear around me ''Random Pony'' (surprised) wait a minute look! Celestia opens her eyes as does the mane 6. "Rarity" (in awe) it's so pretty. "Twilight" I haven't seen anything like it before. "Celestia" (Happy) well then I guess that answers our question. She then gives me a book with a weird symbol on it.
