Owen (born 2001) is a teenager who attempts to prove his late father's innocence of a crime he did not commit.
In 2016, Owen was recruited by Monroe who asked him to join a group of other teenagers who like him had Templar or Assassin ancestors, in order to find a Piece of Eden, the Trident. The group, which in addition to Sean was composed of Owen, Javier, Natalya and the siblings Grace and David, accepted after Monroe told them about the Assassin-Templar War.
At some point during Owen's childhood, his father was arrested for the hold-up of a branch office of the Malta Banking Corporation. Owen believed him when he maintained his innocence but his father, who had a tumultuous youth, was nevertheless convicted and later died in prison.
Following his father's conviction, Owen and his mother went to live with his maternal grandparents. Owen had a difficult time with his grandfather who was convinced that Owen would eventually follow his father's path.
In 2016, despite the fact that they eventually grew apart, Owen asked his friend, Javier, to help him prove the innocence of his late father. Owen wanted to use a clandestine Animus owned by the mysterious Monroe to relive the memories of his father's supposed bank robbery. However, as the duo met with Monroe, the man told them that he couln't help them as Owen had only access to his father's memories from before his own conception and hadn't any DNA sample of his father taken from after the robbery.
Despite Owen's disillusionment and for the sake of curiosity, they still decided to use the Animus and experienced the memories of two of their ancestors who met during the Spanish conquest of the Aztec Empire. The ancestor of Owen, Alfonso del Castillo, was a conquistador who unknowingly witnessed Hernán Cortés using a Piece of Eden, in fact a prong of the Trident of Eden, to brainwash the ancestor of Javier, a Tlaxcaltec commander nammed Chimalpopoca.
Following this discovery and after Monroe disapeared without answering their questions, Owen and Javier unknowingly became persons of interest for both the Assassins and the Templars. Indeed, a Templar agent tried to approach him on the street some days later, but an Assassin killed him from a nearby roof prompting Owen to flee, escaping the Assassin with the help of Monroe.
After Monroe told them about the Assassin-Templar War and convinced them that the best course of action was to find the artifact first and hide it from the belligerents, Owen and his friend Javier joined Monroe's team of teenagers. Recruited by Monroe, they all shared into their DNA, the ancestral memories of the same event: the 1863 draft riots in New York City, during which the prong was used again.
Choosing a side
Under the guidance of Monroe and thanks to his modified Animus which allowed multiple users to share their session, Owen relived the memories of the Assassin Varius, while the others looked for clues into the memories of their own ancestors. In 1863, Varius was instructed to recover the hidden prong and deliver it to General Ulysses S. Grant, but was later hunted by Cudgel Cormac, Javier's ancestor. However, the group eventually discovered that thanks to Varius' new recruit and Grace's ancestor, the gifted Eliza, the dagger managed to reach General Grant who kept it until his death.
However the use of the Animus didn't go unnoticed and a Templar strike team captured the teenagers with only Owen and Javier escaping thanks to the skills they learned from their ancestors while Monroe disappeared. As they where debating about their options, the Assassin whom Owen previously met, Griffin, found them back thanks to the tracking device in their stolen Abstergo bike.
Griffin convinced Owen to trust him, and the teenager in turn convinced his reluctant friend to work with the Assassins. The teenagers revealed to the Assassin the location of the Dagger, in Grant's house. After Griffin prompted them to use Eagle Vision to see if was truly trustworthy and after he promised to secure the Brotherhood's help in order to prove that Owen's father was innocent of the crime he was arrested for, he brought them to his safe house.
After equiping themselves and receiving a call from Gavin Banks, who revealed that the Dagger was in fact a prong of the Trident of Eden, they took a private plane to New York and from there drove to Grant's house. However, Monroe arrived there first and left with the artifact before, the stash being empty. Before they left, three helicopters filled with Templar agents arrived to the house and after Owen destroyed two of them with a grenade, they escaped.
