Galactica Cavil
the priest in the fleet
Galactica Cavil was a Number One model humanoid Cylon who evacuated the ruins of Picon during the Fall of the Twelve Colonies and reached the refugee fleet. Welcomed aboard Galactica as a priest, he formed and led a hidden cell of humanoid Cylons working to destroy the fleet from within.
John Cavil, known as "Galactica Cavil", was a Number One model humanoid Cylon. During the Fall of the Twelve Colonies he was evacuated from the ruins of Picon and went on to establish a religious office aboard the battlestar Galactica. (Battlestar Galactica: The Plan)
On the eve of the attack#
Two weeks before the Cylon assault, Galactica Cavil and another copy of his model stood aboard a Resurrection Ship near the Colony, looking over the waiting resurrection bodies of Saul and Ellen Tigh, Galen Tyrol, Samuel T. Anders and Tory Foster, the so-called Final Five survivors of the Thirteenth Tribe that had created the humanoid Cylons. The Ones expected the Five to die in the attack and wake in these bodies. (Battlestar Galactica: The Plan)
Drawn to Ellen, Cavil resolved to seek out her living counterpart on Picon. He found her in a bar, the Club Pink Moon, and drew her into a conversation about whether people can change, ducking her question about whether he was a priest. Frustrated to discover that she lived a carefree life with no regrets, he shielded her when the nuclear blast hit the city and, as SAR Raptors combed the ruins, told the wounded Ellen she was not going to die yet because she had more left to learn. (Battlestar Galactica: The Plan)
Joining the fleet#
Against expectation, the Raptor delivered the two to Rising Star, a civilian ship in orbit. The vessel soon met with a refugee fleet led by the newly appointed President Laura Roslin and defended by Galactica. (Battlestar Galactica: The Plan)
Over the following week the Cylon forces consistently failed to destroy the fleet. Cavil left Ellen behind and transferred to Galactica, where he was given the use of the chapel as a priest. (Battlestar Galactica: The Plan)
The cell aboard Galactica#
From his position aboard Galactica, Cavil handed out flyers that carried a secret codeword for humanoid Cylons hidden within the fleet. Soon afterward he formed a cell drawn from the other models, bringing together a Number Two, a Number Five, two Number Sixes and a Number Eight working as a sleeper agent. Among those who answered the call and joined the cell under his command was the Number Six copy known as Shelly Godfrey, who took part in the cell's plans for acts of violence against the fleet. His side of these months is one half of the TV film The Plan. (Battlestar Galactica: The Plan; Battlestar Galactica, "Six Degrees of Separation")
