—Vevec, about Chernan Ordo, a possible offspring of Eldar Ordo
Eldar Ordo was born prior to 55 ABY on the Outer Rim world of Mandalore to Neshri Eldar and Ghebiin Ordo, both of the Mandalorian Clans. Though he was raised mainly by his grandmother Aadila Ordo―the daughter of the renowned Mandalorian warrior Rage Ordo, Eldar's forefather―his father Ghebiin was responsible for his traditional Mandalorian training, and had successfully guided him through the verd'goten.
Upon reaching adulthood, Eldar Ordo joined the famed group of Protectors, safeguarding the citizens of Mandalore. Designated a supercommando, Eldar was responsible for managing his ancestral tribe that operated as a unit within the army of Protectors, the Shadow Mandalorians or Mando Werda. Under his leadership, Mando Werda soldiers maintained security within the city of Sundari and the northern region of the Mandalore Space.
At some point before 81 ABY, Eldar Ordo had married a female Humanoid Mandalorian. The two later conceived a child who was born prior to 104 ABY on Mandalore; though the name of the child was unknown, many contemporaries in 130 ABY considered late Mand'alor Chernan Ordo an offspring of Eldar Ordo.
