- For other uses of "Cyrannus", see Cyrannus.
Cyrannus (also spelled "Cyranus") is the name of the solar system containing the worlds of the Twelve Colonies of Man in the Battlestar Galactica video game, published in 2003.
The 2003 video game has its own continuity (as opposed to the Re-imagined Series or Original Series) that draws from elements of the Original Series and the Thousand Yahren War and elements apparently slated for the first revival attempt of "Battlestar Galactica" as a new TV series by Bryan Singer and Tom DeSanto in 2001.
- No aired episode of the Re-imagined Series has used "Cyrannus" as the name of their solar system. Therefore, the official name of the solar system of the Twelve Colonies for the Re-imagined Series is unknown.
- It's not known in the video game whether Cyrannus is a single star with multiple life-bearing planets, or a binary, a trinary star system, or an open cluster of stars.
- This information is part of a separate continuity that mixes elements from the Re-imagined Series and Original Series as well as unique material. It is not a canonical item in either series.
