Doctor Amorak was an associate of Gaius Baltar's at the Colonial Ministry of Defence. He apparently survived the Cylon attack, escaping aboard the liner Olympic Carrier, itself destroyed on the order of President Roslin when the ship appeared to have fallen into Cylon hands (33).
Amorak alleged that he held information pertaining to the betrayal of humanity, and a request for him to meet with Roslin in order to divulge this information had been received by Colonial One. However, before the meeting could take place, the Carrier failed to make n FTL jump with the rest of the fleet. When the liner did eventually reach the fleet, some three hours later, it was under Cylon control and carrying nuclear warheads, prompting its destruction (33).
Later, a corporeal version of Number Six calling itself "Shelly Godfrey" arrived aboard the Galactica, claiming to be Amorak's assistant, and with alleged evidence of Baltar's complicity in the Cylon attack on the Twelve Colonies (Six Degrees of Separation).
At no time it is clear whether or not Amorak was aboard the Olympic Carrier. or whether the use of his name in the events of 33 (as with the events of Six Degees of Separation) was a ploy by the Cylons to further manipulate Dr. Baltar and draw him further into their influence.
