Errol Navis (2822 - 2931) was an accountant and amateur explorer best known for his 2861 discovery of the Oso system. Born on Carteyna (Cano II) to two geoengineers, he became an accountant at Shubin Interstellar in 2843 after completing a mathematics degree. Later attributed to a childhood spent in a series of confined, environmentally-controlled bases, Navis described himself as harboring a strong desire to live in a world with open skies and a breathable atmosphere. When Shubin denied his transfer request to Terra (Terra III), Navis purchased a small ship, which he used to take himself and his young daughter Oso on weekend trips to exotic locations. During one of these trips, his scanners picked up an anomaly in the outskirts of the Castra system that turned out to be a jump point to an undiscovered system. He used the reward money from the United Empire of Earth (UEE) government to buy a home on Terra and start a business as an accounting consultant.
