Princess Celestia has spent 1000 years waiting for Luna's return. During the years Celestia has changed. She became depressed and sank into guilt over what she had done to her younger sister. Now that she is back she will do her best to fix things....except....Luna is different. Sure her coat is a bit different and she looks a bit younger than she was before but it's the way she acts and reacts that's so...unsettling for the older Princess. It's almost like she's a new mare.

Meanwhile, Luna is left to explore a new world while doing her best to avoid her sister and her overbearing nature, while also trying to find happiness again after someone dear was taken from her.

And then there is Twilight Sparkle, she got unintentionally dragged into the whole mess and then dragged herself even further by accident. Now she has to deal with a sad overprotective desperate version of her mentor AND a living mystery of an Alicorn who might be the definition of opportunistic and selfish....for the most part.
