What is the name of the fictional organization that later becomes the Templars in Assassin's Creed?

The Order of the Ancients is the organization that later becomes the Templars in Assassin's Creed lore.

Assassin's Creed Origins presents the Order of the Ancients as a secretive network operating in the ancient world. Its members seek control and impose their vision through political influence and manipulation. Bayek and Aya oppose the order while investigating the forces responsible for personal and political violence in Egypt.

The organization is a predecessor to the medieval Templar Order rather than a completely separate enemy tradition. Later games depict the Templars as the recurring ideological opponents of the Assassins, while the series uses different historical names for related groups in earlier periods.

The Hidden Ones are the organization founded by Bayek and Aya and are the predecessors of the Assassins. Abstergo Industries is a modern corporation, and the Cult of Kosmos is the major enemy organization in Assassin's Creed Odyssey.
