"Some friendships are so strong, they can even transcend lifetimes." - Avatar Roku

It has been five centuries since Twilight became the Princess of Friendship.

Ponies from her glorious past have moved on to the next life. Her friends have all passed away.

But she never had the chance to say goodbye.

Can five ordinary, unrelated mares help her get through to them?

Inspired by the quote made by Avatar Roku about friendship.
