Fifth Corsair
From Tardis Wiki, the free Doctor Who reference
The Fifth Corsair once got drunk with the Doctor and woke up with him either in jail or the vaults of the Bank of England. She had the smallest Ouroboros tattoo of any of the Corsair's incarnations, with it being the size of a ten pence piece and located on her upper thigh.
