Artemisia is a crazy liquor pixie written by Ree. Missy embodies the purportedly hallucinatory and inspirational properties of absinthe, as well as the simple alcoholic effects.
As you may well imagine, she's totally off her nut.
If you ask her about herself, she may tell you that she's a fae, a muse, or a red-eyed flying squirrel en route to Greenland.
Her true form is an eight-inch-tall (~20cm) green woman with wings. The green is everywhere: eyes, hair, skin, clothes. The wings are about the length of her green gams and appear much like dragonfly wings.
She generally disguises this somewhat (see her Magic).
Missy practices a manipulation somewhere between illusion and induced hallucination, whereby she can make people see outlandish sights and believe they are real. She uses this often to appear human-size. She can assume total human appearance, but does so only among human beings; completely hiding her wings makes them itch and masking her green skin feels likewise.
When appearing "tall" (her word for it), the pixie her generally flutters within the head area of her illusive self. The illusion completely masks her from view. When she doesn't mind her spell, her "feet" may not quite touch the ground completely, or her "hand" could go right through a solid table. Unless she modifies it, her illusion mirrors her actual self; if the real pixie raises her left hand, so does her human-size illusion. Tweaking her illusion requires extra effort, so she rarely bothers unless she has a reason.
She has also been known to use more complex illusions to disguise herself as an empty glass or liquor bottle, generally to spy on people coping with the aftereffects of her mind games. The further the strays from her basic "magnified" illusion, the more she must concentrate to maintain the effect, so advanced disguises are uncommon.
Like all of her breed of pixie, Artemisia must regularly ingest a certain amount of her element to retain her abilities and health. Any alcohol works in a pinch, but real absinthe is best, and the more expensive the better.
