- "I tried to be a good father when I was there. But I allowed myself to become distracted from the order, from my true purpose."
- ―Alejandro Ortega de Márquez.[src]
Alejandro Ortega de Márquez (unknown – c. 1707) was a Spanish privateer and Templar that was active in the Caribbean, conquering several small islands in the name of King Philip V of Spain. Despite rumors that he had lived a year among the Taíno, possibly even taking a Taíno bride and fathering one or more children, Alejandro eventually attacked one of their settlements and was killed in the ensuing battle.
Due to his occupation, Alejandro's presence at home was rare, with some of his children, such as Lucia Márquez, growing up without ever meeting him. Consequently, they struggled to make ends meet and were forced to take to the streets to survive.
In 2013, his 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 Adventurer.
- Alejandro is the Spanish variant of the Greek name Αλεξανδρος (Alexandros), meaning "protector, defender of men". Ortega is derived from Latin urtica, meaning "nettle". Márquez is a Spanish surname meaning "son of Marcos".
- It was speculated by a number of Abstergo Entertainment researchers that Alejandro may well have fathered Opía Apito, which if true would make Lucia and Opía half-sisters.
