The Magi Sentinels were an organization of robed individuals who protected the monarch of Onderon around the time of the Freedon Nadd Uprising in 3998 BBY. They were guarding King Ommin's subterranean fortress when Satal and Aleema Keto arrived for his aid in translating a Sith spellbook they had stolen. By the time of the Clone Wars in 22 BBY, the Magi Sentinels were long bygone, but the genetic abomination known as Zeta Magnus wore vestments that resembled theirs.
