"Yeah, an evil version of Princess Celestia came through the mirrors, so after she was defeated, Her Highness destroyed one of the magic mirrors.

Nephenee looks confusedly at a hoof. "Ah wonder why Ah stayed in my pony body...or how long Ah'm stuck here...thank Celestia it don't seem to be the same timeline when folks vanish..."

Realizing she's being rude, there's a sheepish chuckle as she rubs the back of her head. "Oh, Ah'm sorry. Plum forgot to introduce myself. Ah'm Nephenee."
