History
The Moxolon Swamp Vipers lived on a swamp planet in the Calysteral Cluster that the Judoon used as a prison. The planet was twenty million square sentons in area and filled with quagmire.

Androvax was bitten by a Moxolon Swamp Viper before escaping the planet. Before he died, he wished to free one hundred of his species that were cryogenically frozen and had crashed on Earth. (SJA: The Vault of Secrets)
