It's been uncounted millenia since the last of Twilight's first friends passed away. Even their names have passed into legend and myth, forgotten by the slow march of time. Now on a far away planet, she finds her musing upon all of her friends over the long years interrupted by her latest faithful student, Calming Waltz.
Now if she can only get that silly pony off to her wedding, and maybe teach her something about why her romance and wedding to come is so special and wonderous... Or at least something for Twilight to get a laugh out of, anyway.
