Sabina Merrin is the handmaiden of Queen Ileosa Arabasti.
She is a beautiful woman dressed in magnificent full plate armor and appears to be more than just a handmaiden: She quite obviously also fulfills the roles of bodyguard and closest companion of the Queen.

It is said that she has studied swordplay under Vencarlo Orisini himself at his Academy. Even though it would fit right in, she claims not to know Grau Soldado.
