The Line of Tellus was a family line within Romulan society. In 2382, this group publicly denounced Praetor of the Romulan Star Empire Tal'Aura and withdrew their members from government service. In 2385, after the death of Praetor Tal'Aura, Proconsul Sela replaced a number of populist senators from representatives of the noble houses one of which included the noble Chulan from the Line of Tellus.
