Clan Ordo was a famed clan of Mandalorians who presided over the moon Ordo in the Mandalore Sector for their Lord Mandalore, the ultimate official over the Mandalorians. The most famed clan member was Canderous Ordo, who fought during the Great Sith War, Mandalorian Wars, Jedi Civil War, and the First Jedi Purge.
He accompanied Revan during the Jedi Civil War and later, in accordance with orders from Revan and the interest of his people, reunited the Mandalorians under his banner as Mandalore. At some point between the years 3,955 and 3,953 BBY, Canderous Ordo returned to the former Mandalorian headquarters on the Onderonian moon Dxun and began to reunite and rebuild Clan Ordo.
During the Galactic Civil War, the spy known as Bloodletter owned a pair of Mandalorian pistols that supposedly had belonged to the patriarch of Clan Ordo.
