An unnamed swamp prison planet existed in the Calysteral cluster, one of several swamp planets in the cluster. It was used by the Judoon as a prison facility, was twenty million square sentons in area, and was filled with quagmire. It was also inhabited by the venomous Moxolon Swamp Viper. Androvax once acquired a disk from a Bouken pirate he met here, which would grant him access to the vault on Earth owned by the Alliance of Shades. (TV: The Vault of Secrets)
