Ragnar
the gas giant of the Cyrannus system
Ragnar was a gas giant in the Cyrannus Star System whose hydrocarbons drove the economies of Canceron and Aerilon. It saw a costly battle early in the Cylon War and later hosted the surplus depot of Ragnar Anchorage.
Ragnar was a gas giant on the outer edge of the Colonies' home system, the Cyrannus star system, and the site of the munitions station Ragnar Anchorage. After the Fall of the Twelve Colonies, Commander William Adama ordered all surviving ships to meet there. (Battlestar Galactica (miniseries))
Storms and radiation#
Ragnar was wracked by violent storms, and the Anchorage sat in a pocket of relative calm within them. The storms threw out strong electromagnetic discharges that interfered with a ship's systems, including its ability to plot FTL jumps. That hid the station from enemy scans, but it also meant a ship had to climb above the storms before jumping. The storms also gave off radiation that harmed Cylons, and when Leoben Conoy fell sick on the station, it gave Adama his first clue that Conoy was a Cylon. (Battlestar Galactica (miniseries))
Reaching Ragnar#
Ragnar lay days away from Galactica at sublight speed, with the Cylon fleet in between, so Adama ordered a risky FTL jump. Colonel Saul Tigh warned that a small error could put the ship inside a sun instead. The jump succeeded, and Galactica entered the gas giant's upper atmosphere to rearm at the Anchorage. (Battlestar Galactica (miniseries))
Ragnar Anchorage and the exodus#
President Laura Roslin's civilian convoy was the only group of ships to make the rendezvous. When Cylon basestars arrived, Adama placed Galactica between them and the convoy, giving the civilian ships the cover they needed to climb above the storms and jump away. It was the last battle fought in Colonial space before the survivors left for good. (Battlestar Galactica (miniseries))
Frequently asked questions
- What was Ragnar in Battlestar Galactica?
- Ragnar was a storm-wracked gas giant on the outer edge of the Colonies' home system, and the site of the Ragnar Anchorage munitions station.
- Why was Ragnar useful to the Colonial Fleet?
- Its storms threw out electromagnetic interference that hid the Anchorage from scans, and radiation that harmed Cylons. The catch was that ships had to climb above the storms before they could plot an FTL jump.
- What happened at Ragnar during the Fall of the Twelve Colonies?
- Commander Adama ordered all surviving ships to Ragnar. Galactica rearmed at the Anchorage, met Roslin's civilian convoy there, and then held off a Cylon force while the civilian ships jumped away.

Cylon
The Cylons were a race of sentient machines created as military robots by Graystone Industries on Caprica. Built from research into artificial consciousness, they rebelled against their human masters, fought a long war, and forty years later returned to annihilate humanity.

Cyrannus: the Colonies' four suns
Four stars in a double binary, Helios Alpha through Delta, holding all Twelve Colonies. Refugees from Kobol settled them two thousand years back.

Fall of the Twelve Colonies
A single day of Cylon attack killed billions of people across Colonial space. Barely fifty thousand escaped in a refugee fleet.

FTL drive: spool up and jump
Human and Cylon ships jumped instantly between points in space once the drive was spooled. Precise sums kept Galactica ahead of its pursuers.

Galactica
Galactica was a Jupiter-class battlestar that served the Colonial Fleet from the Cylon War until the discovery of Earth. Never networked, it survived the Fall of the Twelve Colonies and shepherded the last fifty thousand humans across uncharted space before being scuttled into the sun.

Laura Roslin: the dying leader
Secretary of Education until the Cylon attack killed everyone above her. Sworn in as President, she became the dying leader of Colonial prophecy.

Battle of Ragnar Anchorage
The Battle of Ragnar Anchorage was an engagement between Colonial and Cylon forces during the Fall of the Twelve Colonies. It came as Galactica re-armed at the anchorage and gathered the first survivors of the Fall, then held off the Cylon basestars while the civilian fleet escaped.
Colonial One
Colonial One was a civilian passenger liner that became the official residence and workplace of the President of the United Colonies of Kobol after the Fall of the Twelve Colonies. Formerly Colonial Heavy 798, it served as the seat of the surviving government throughout the search for Earth.
Cyrannus: the Colonies' four suns
Four stars in a double binary, Helios Alpha through Delta, holding all Twelve Colonies. Refugees from Kobol settled them two thousand years back.
Fall of the Twelve Colonies
A single day of Cylon attack killed billions of people across Colonial space. Barely fifty thousand escaped in a refugee fleet.

Galactica was a Jupiter-class battlestar that served the Colonial Fleet from the Cylon War until the discovery of Earth. Never networked, it survived the Fall of the Twelve Colonies and shepherded the last fifty thousand humans across uncharted space before being scuttled into the sun.
Lee Adama: Leland Adama, callsign Apollo
Commander Leland "Apollo" Adama was a Colonial Fleet officer, the sole surviving son of William Adama, who served as Galactica's CAG before turning to politics as the Caprican delegate to the Quorum and, in time, interim President of the Twelve Colonies.
Number Five
The Number Fives were a model of humanoid Cylon, all of whom went by the name Aaron Doral. They infiltrated Colonial society before the Fall of the Twelve Colonies and are believed extinct after the Cylon Civil War.
Olympic Carrier
The Olympic Carrier was a civilian passenger liner that escaped the Fall of the Twelve Colonies with the refugee fleet, only to be destroyed on suspicion of carrying a Cylon nuclear device five days after the exodus began.
Ophion: the captured gas giant of Helios Gamma
Ophion was a large, frigid gas giant orbiting the star Helios Gamma in the Cyrannus Star System. Studies suggested it was a rogue planet captured by the system, an event that also shifted Ragnar into its present orbit.
Ragnar Anchorage
Ragnar Anchorage was a Colonial Fleet supply depot in orbit of the gas giant Ragnar. Semi-abandoned by the time of the Fall, it became the rallying point where Galactica and the civilian fleet rearmed before fleeing into deep space.
William Adama
William "Husker" Adama was a Colonial Fleet officer who commanded the battlestar Galactica through the Fall of the Twelve Colonies. His refusal to network the ship spared it from the Cylon attack, and alongside President Laura Roslin he led the survivors of humanity in search of a new home.
