|Are you looking for Starlight Glimmer?|
This isn't the right place! This OC is very different and was created three years before the similarly-named villain existed.
A slightly spacey, soft-voiced unicorn poet who tends to "float" around town late at night. She loves to sing as well, and her voice has a sort of ethereal beauty to it.
Some of her poems have been made into very down-tempo, ambient-styled electronica tracks with the help of her housemates and Ellie Phantasie.
One of her favorite haunts is a clearing just south of Ponyville proper, with a small hill and oak tree in the middle of it. You might find her there late one night, humming a quiet tune or waxing philosophic.
She recently became one of Twilight Sparkle's librarians, in an effort to have a more stable lifestyle.
