Dastor was Servalan's aide at the time of the harvest of Kairos. He urged her to attack the Liberator while it was in orbit of the sopron planet, telling her about construction worker Jarvik's claim that she was afraid to face Tarrant and anyone could take the Liberator with three pursuit ships. Servalan told Dastor to bring Jarvik to her and together they observed as Tarrant evaded Servalan's trap.
Dastor confirmed to Servalan and Jarvik that the Liberator was en route to Kairos. He later answered a message from Shad about the kairopan shipment before Servalan took over the communication. When Jarvik was put in charge of defending the shipment, Dastor gave him information on the escort shuttle. (C: The Harvest of Kairos)
