Born in the 15th century, Álvaro de Espinosa was an experienced Spanish mercenary and leader of a small band called the Lobos Silenciosos, or 'The Silent Wolves'. His group was contracted by the Spanish crown to make war against the Moorish Emirate of Granada.
In his many travels, he met a tomboyish, peasant girl named Andrea Cortés, and, seeing her desire for a more fulfilling life, he took the girl under his wing. Over the years, he taught her everything he knew about combat, eventually regarding her as the daughter he never had.
Unlike other mercenaries or Spanish soldiers, Alvaro respected the Muslims and their culture. He expressly forbade the ransacking of Muslim homes, which was a common occurrence after the fall of a city or village.
As Spain marched closer to victory, the crimes and atrocities committed by the Inquisition in the name of God increased. Alvaro grew more and more disgusted by their actions and insistent on respecting his fallen enemies. With the exception of Andrea, his men slowly began to abandon him, not sharing his reticence towards their enemies.
With few men still at his command and no desire left to fight the Muslims, Alvaro ended up in Guadix, where he was approached by the old Mercenary General Domingo De la Torre. Sensing Alvaro's discontent, Domingo offered an invitation to join forces with the Assassin Brotherhood and fight for a cause larger than nations or religions. Knowing of Domingo's legendary accomplishments and impressed by the man, Alvaro was convinced by his words and agreed to fight for the Assassins' cause.
