Cabell was a male Tirolian who lived during the reign of the Robotech Masters. He himself was not a Master, and was born naturally. According to some sources, Cabell was an elderly scientist who was a mentor to the young Zor who was a brilliant member of the scientific community. He sponsored him during his attempts at finding new alternative sources of energy for Tirol which saw Zor engage in space exploration. His activities led to the discovery of Optera and the Invid Flower of Life which he experimented on to create Protoculture. Cabell worked alongside Zor as a contemporary of him when he developed the Protoculture Matrix. (Legend of Zor)
