Andrea Cortés was a mercenary of the militant group Lobos Silenciosos who, under the direction of Álvaro de Espinosa, joined the Spanish Brotherhood of Assassins when Álvaro pledged his group to their cause.
The daughter of pig farmers, Andrea Cortés was the only girl of her parents' eight children. She loathed her impoverished life as a peasant spending all her days attending to pigs. As a reprieve from the monotony, she regularly engaged in sword-fighting and wrestling with her brothers, all of whom were members of the local militia.
One rainy night, a group of mercenaries named "The Silent Wolves" led by Álvaro de Espinosa offered to pay more gold she had ever seen for a single night of shelter on her family's farm. Thrilled by their stories of gold and riches, she packed her things and left with Álvaro the next morning. Under Álvaro, Andrea was trained into a full-fledged mercenary, and over time, she came to regard him as a second father.
When Álvaro attempted to convince his mercenaries to serve the cause of the Assassins, most of them dissented and left, but Andrea was among the few who remained loyal and assented to joining the Brotherhood with him.
Personality and traits
Growing up as the only girl among seven brothers, Andrea Cortés developed a fierce tomboy personality. She prided herself as a tough individual who reveled in the sparring sessions she participated in with her brothers. With a nature as aggressive as hers, she only felt violently constrained by the docile and repetitive life of a destitute peasant.
When mercenaries offered her an escape from this life, she was easily lured by their promise of wealth and adventure. In spite of this, she supported the decision of her boss Álvaro to change their service to the Assassins rather than mere gold. This was controversial to many of their comrades, but her respect and loyalty to the man she had grown to see as a second father was too steadfast for her to disapprove.
