Sir Aubrey Hague was a member of the British Rite of the Templar Order, an executive in the East India Company and the father of Matthew Hague. A shrewd businessman, he was the biggest landowner in Bristol during the early 18th century.
In 1711, Caroline Scott was betrothed to Aubrey's son Matthew. While Matthew pretended to be an experienced businessman like his father, he had little skill at it, and was liked by few. As such, Caroline was won over by the charms of Edward Kenway, a young Welshman, and married him instead. The year after, the Kenway farmstead was attacked by the Templars, and Edward was press-ganged aboard the Emperor.
In 1723, Edward returned from the Caribbean, having become an Assassin. He mistakenly believed the Hagues to have been involved in the attack on his family, and therefore intended to kill Matthew. After killing the Templars Emmett Scott and Wilson, Edward locked Matthew inside the cabin of the latter's ship, the Charlotte. As Edward prepared to burn the ship, Aubrey and British First Lord of the Treasury Robert Walpole arrived, accompanied by a contingent of soldiers.
Aubrey told Edward that he had come to plead clemency for his son. In response, Edward asked the two to show their fingers. A Templar ring was revealed on Aubrey's finger, confirming his allegiance. Walpole assured the Assassin that the primary perpetrators of the attack were already dead. Upon being offered pardons for himself and the crew of his ship, as well as property in London, Edward accepted and let Matthew return to his father.
- In 2015, his name was on a list of known British Templars used by the Templar Isabelle Ardant.
