What organization do players build in Assassin's Creed Origins?

Players build the Hidden Ones in Assassin's Creed Origins. The organization is founded by Bayek of Siwa and Aya during the game's story and becomes the direct predecessor of the later Assassin Brotherhood.

The Hidden Ones emerge after Bayek and Aya confront the Order of the Ancients, a secretive group manipulating political power in Ptolemaic Egypt. Their new creed emphasizes operating from the shadows and protecting ordinary people from domination.

Origins therefore depicts an earlier stage of the series' mythology. The familiar name Assassin Brotherhood is not yet the organization's established title, and the iconic finger-blade tradition is shown developing through the founding narrative.

The Order of Ancients is the principal opposing organization, not the group the player builds. The Rooks belong to Assassin's Creed Syndicate, while the Colonial Assassins are associated with Assassin's Creed III, making those alternatives distinct factions from different eras.
