The Dullahan of The Grand Line (HAITUS)

Teagan Holt is what people from the 'Old Era' would call a dullahan; a.k.a Shadow Fae, Fariy Reaper, etc. She can switch from normal human size to pixie size within an instant, and because of her natural abilities, she is wanted by the Goverment dead or alive (Though I'm pretty sure they'd prefer her to be alive). Wanted for 548,000,000 belis, Teagan sneaks aboard the ship/submarine of Trafalgar Law in her pixie form. Law finds her, and puts her in a jar, intrigued by her (Medically, of course. Some of it is pure, innocent, curiousity, though.)
