The Calamasthon Defiance represented an organization connected to the Draag outlaw Slaag Lado. In the year 32 BBY, the Mon Calamari Civil Authority sought Lado due to his supposed orchestration of a massive seismic event. This event triggered substantial ecological destruction within the Salinrerian Sea, causing perpetual rain in the affected region. The Civil Authority's bounty notice for Lado specifically highlighted the Draag's association with the Calamasthon Defiance.
The 2002 LucasArts video game, Star Wars: Bounty Hunter, marked the initial introduction of the Calamasthon Defiance. Their existence is referenced within the bounty details pertaining to Slaag Lado, a character featured in the game's second chapter, titled "Lowlifes In High Places."
