What name did the ancient Egyptian Assassin group use in Assassin's Creed Origins?

The ancient Egyptian Assassin group in Assassin's Creed Origins is called the Hidden Ones.

Bayek and Aya establish the Hidden Ones after confronting the Order of the Ancients, a secret organization seeking political influence in Ptolemaic Egypt. The new group adopts principles of secrecy, resistance to tyranny, and protection of ordinary people.

Origins presents the Hidden Ones as the predecessor of the later Assassin Brotherhood. Its members use hidden blades, operate covertly, and maintain bases where recruits can be trained. The group's earliest development explains how familiar Assassin customs emerged within the series' fictional history.

The Order of the Ancients is the enemy organization in Origins, not the Assassin group. The Children of Danu belong to a different faction in Assassin's Creed Valhalla: Wrath of the Druids.
