Callinoe Darros is from the planet Destri.Lomara. Trained as a geneticist, he worked for many years for the Intergalactic Union Scientific Division, studying alien DNA. After his planet was taken by the Agroaki, Cal lost his place in the Scientific Division, and instead went to work for the Fugitive Retrieval department, where he used his races’ empathic abilities to track down and detain criminals.
