Calufrax system

The Calufrax system was a binary star system with seven planets, one of which was Calufrax until it was destroyed by Zanak in 1978. (PROSE: The Pirate Planet)

Whether or not the system also contained Callufrax Minor (TV: The Stolen Earth) or Calufrax Major (PROSE: The Secret in Vault 13) was unknown.
