Ragnar is a gas giant in the Cyrannus star system and periodically changes orbit around the Helios Gamma and Helios Delta systems, resulting from Helios Gamma's capturing of the rogue planet, Orphion which disrupted the orbits of nearby planets. In the years before the First Cylon War, advancements in colonial space technology made the exploitation of Ragnar's hydrocarbons a serious endeavour for Canceron and Aerilon's economic success. Following the War, Ragnar became the site of a surplus depot known as Ragnar Anchorage, and was the site of a final battle between the Colonial Fleet and the Cylons before the human exodus.
