Twilight finds herself struggling without a clear path in front of her as a princess. In a bout of panic, she seeks out her mentor, Princess Celestia, in the hopes of gaining answers, only to find herself with some much more distressing questions.
With a decidedly unexpected guest making herself comfortable in Canterlot Castle, it quickly becomes evident that her mentor has been keeping some interesting company over the years. Twilight quickly begins to realize just how much things are going to change for her. She's practically immortal. Which, apparently, means she's going to be spending a lot of time with beings a lot less mature than they first seemed.
(First Story-Woot. Likely to be broken down into three parts.)
