I haven't gotten very acquainted with any of the new CBers, but I'll try! These are probably not creative at all, and mostly based off of your names. They are also going to be strange and not resembling established fantasy creatures at all. 

Brooke E. is a water nymph, with light blue flowy clothes and a laugh that sounds like River bubbles; she sits in streams and smiles a lot and her teeth are v white and her eyes are blue.

Winter Firefly is a warm yellow glow, floating outside a Chicago window in the midst of a storm. She's got a short, floaty sort of yellow dress and her hair is kind of like Sophie's at the end of Howl's Moving Castle.

Indigo K. is mysterious; she wears a long white cloak and her hair is long and purple-ish and almost gravity defying; it tumbles around her as she rides a horse through the night.

BookBug is small and quick; she's got red hair and a cap and ears pointed at the tips, and she scurries along library shelves, putting the books where they belong.

Nora the Singer is light and graceful; she's thin and tall and has long silvery hair and a robe that looks vaguely Greek; in fact, she's got a laurel crown as well.

Madeleine is elegant; perhaps a spin of light pink butterfly wings and dark red frills

Daffodil is a bright yellow cap and tilted head; sharp chin and jet-black eyes, grinning at you from within a flower. 

And now for some oldies! (Sorry if any of the above are oldies, the following are just the people I recognize)

BHR is an elf, with blond (DUH) hair in braids pinned atop her head, and  a long blue dress that touches the floor. 

True S. is midnight blue and stars and bright eyes; a constellation and a shooting star, piercing yet comforting

Theo W. is fire; she's got short black hair and a crown of burning flowers, and she dances a lot

 
This really made even less sense than when I set out to do this, but such is life. I can do more later, I'm pretty sure I forgot some.  

Wait - I knew I'd forgotten a few. 

SC is a dragon slayer. That is gloriously uncreative, but I can't help it. She wears armor and her hair is black and cut short; she has an ornate sword and a dark blue cloak.

(Later, I should imagine all of you as lady knights. That'd be cool. Except the rare boys, who will be of course normal Knights, I just like lady knights a lot.)

Little Sister has soft fluttering wings and glows faintly; her blue eyes are almost hypnotic and she sings a soft tune

Maple Syrup is in a tree, and she has long auburn hair and freckles and a plaid button-up shirt. Her hair is in two braids down the sides of her neck, and all of the animals of the autumn forest do her bidding if she so chooses. 

(And now you guys had better do me bc I'm incredibly curious.)  

Wow. I did used to go by True S., didn't I? I dropped it a year or so ago,because it used to be that everyone was doing first name, last initial. That fad has feded out with many of the CBers who keep coming back. I haven't realised how long I've actually been on CB. 

Katia: A petit girl with soft brown eyes, and braided dark brown hair. Wearing a once colorful, now faded scarf/shawl over your head, with a dress that has amazing detail and looks as though it will keep you warm. Braclets and necklaces jangle on yyour wrists and neck. You're a gypsy child, with a vivid imagination. But this image is faded - like an old faded yellow picture. (Actually, I imagined you like a child from Russia or Poland who was coming to America as an immigrant, but realized this was fantasy picturing, and changed it around. The picture was based on your name.) 

As Fantasy Quill and Tiffany, you're a knight with tarnished armor, a red plume our of your open helmet, the trace of golden curls, and blue sparkling eyes. A wall of books sparkling by some magic power surrounds you, and you're smiling, happily. It's the perfect battle for you.

Somebody do me!!!!!!!!!!!!!!!

Lil' Sis, you're a mischievous pixie, with a yellow dress and golden hair, twisted up in a bun.

Masked
Piester: You are a brownie (For those of you whom have read Fable
haven)
however, you don't fit in, you were a cape with a P on it, high-tops,
stretchy pants, and a bag full of pies! Oh and you invented Mountain
Dew....

Meeee?

Ohhh, I like that, I might have to go as one of these for Halloween!!

*Memorial*

Lottie T: Lottie is a kind-natured Victorian girl with a poofy frilly pink dress, blue eyes and tumbled golden curls.

Mag Fan: an enchanting Japanese geisha, holding a feathery tastled maroon fan. Mysterious and cunning, disappears in a poof.

Any others to add to *Memorial*?
