Aravesh ch'Vrane was an Andorian chan serving in the Federation Starfleet in the 24th century. He was a xenobiologist and was assigned to the USS Enterprise-B in the 2300s. In the year 2303, ch'Vrane began dating the couple Demora Sulu and Vanetta Angelis. Despite Lieutenant Commander Sulu being the Enterprise's first officer, their relationship was not inappropriate as ch'Vrane did not report directly to her - there were several steps between them in the ship's command structure.
