What was the name of the precursor organization to the Templars in Assassin's Creed Origins?

The Order of the Ancients was the precursor organization to the Templars in Assassin's Creed Origins.

Origins depicts the Order as a secretive network operating in ancient Egypt and surrounding regions. Its members pursue control through political influence, manipulation, and the use of powerful institutions. Bayek and Aya investigate and eliminate members as they uncover the conspiracy behind their personal tragedy.

The Order's historical period predates the medieval Templar Order shown in earlier Assassin's Creed games. The series presents these groups as connected across centuries, although the fictional organization is not a direct account of a real ancient institution.

The Hidden Ones are the opposing organization founded by Bayek and Aya, and they later develop into the Assassins. The Knights Hospitaller were a real medieval religious order, but they are not the name sought here. The distinction between the Order of the Ancients, the Templars, and the Hidden Ones is central to the franchise's fictional history.
