- "I remember the day they told me I would be married. I laughed. I cried."
- ―Ferreira de Ortega.
Ferreira de Ortega was the daughter of the Spanish Templar Alejandro Estrada de Ortega. Unlike her brothers, who were groomed from an early age, Ferreira and her sisters were excluded from joining the order, instead destined for a domestic life.
At the age of seventeen, after being told she was to be married to a husband chosen by her parents, Ferreira ran away from home, breaking all ties with her family. From then on, she pursued a "life of adventure", plundering treasure from Mayan ruins and engaging various pirates in battle, becoming a fierce one herself.
In 2013, her genetic memories were used as an Animi Avatar by the entertainment branch of the Templar company Abstergo Industries, to influence the general public via the Animus game console, under the title of the Rebel.
- Ferreira is a variant of Latin ferraria, meaning "iron mine; a place where iron is worked". De Ortega is a Spanish surname that translates to "of Ortega", referring to one of Spain's many villages called Ortega. Ortega itself is derived from Latin urtica, meaning "nettle".
