Pax au Augustus, born in 743 P.C.E., is the son of Virginia au Augustus and Darrow of Lykos.

Pax was born in secret on Virginia’s flagship, the Dejah Thoris, shortly after the start of the Rising. During this time his father, Darrow, was widely believed to be dead. For the first year of his life, until the formation of the Solar Republic, Pax remained in the Asteroid Belt under the protection of Niobe au Telemanus. His existence was made public shortly after his mother’s ascension as Sovereign.

In Iron Gold, Pax is ten years old, and lives on Luna north of Hyperion. He was named for Pax au Telemanus, son of Niobe and a close friend of his parents.
