Earth and Mars are seeking new territories for habitation and agriculture, but Jupiter's hostile environment presents a significant challenge. Can the Legion withstand the attacks from the Beetle Bombs and venomous snakes until backup arrives? Or will they suffer the same fate as many of their comrades who have already perished? The Dragon Queen possesses a devastating weapon in the form of a water-blocking parasite.
