You see Janatha the Ghostly Child.
She appears to be a Half-Elf.
She appears to be very young and taller than average. She has faintly glowing blue-grey eyes and spectrally translucent skin. She has very short, shaggy honey blonde hair with a black streak running through it. She has a pinched face, a sloping nose and thin eyebrows. Disconcertingly, she floats along half an inch above the ground instead of touching it.
She is in good shape.
She is holding a well-worn fluffy blanket in her left hand.
She is wearing a snowflake patterned scarf, a striped stocking cap, a bug-eyed housefly mask, a purple dressing gown, a torn satin backpack, a long flannel nightshirt, and some fluffy yellow slippers.
