I don't know if this is the right place to ask this, but I'm going to anyway.

Can anyone help my find a story? It's about a dragon that is literally a star that somehow got into Equestria. If I remember correctly Luna remembers the star he was because it was always "silent". I think that is how she said it. The dragon then meets one of the mane six; (Fluttershy if I remember.) and I think he saves them from something. I do remember the what he look like though. He was a small brown dragon a little bit bigger than a pony.

PS. Sorry if I messed up in my writing; it's 5:00 AM right now and I just woke up like 20 minutes ago.
