Julia Abatemarco, also known as "Pretty Kitty", is a mercenary and a member of the Free Company. She, along with Adam Pangratt, Lorenzo Molla and Juan Gutierrez had previously been imprisoned in Kovir after being accused of being members of the "Sly cats". After the group was released by King Esterad Thyssen, they left for Redania where they formed the mercenary group known as the Free Company.
Julia Abatemarco graduated from a military academy and is the only (known) female commissioned officer in the armies of the Northern kingdoms. She has participated in the battles at Mayena and Brenna as part of the Free Company, after which, Adam "Adieu" Pangratt asked for her hand in marriage, despite the fact that he was already married.
If Geralt follows Roche's path in Chapter II, he and the commando are ambushed by Adam Pangratt and his mercenaries inside the Tunnel of the Founders while entering Vergen. As Pangratt is at Geralt's mercy after a fight, the mercenary explains that if the witcher spares him, he will leave for Tretogor where a pregnant "Julia" awaits him. To this, Vernon laughingly adds "You knocked up Pretty Kitty? Ah, congratulations, Pangratt. And give her my regards."
