Nuclear Mines were deadly space mines that caused massive nuclear fallout upon impact and were invented by the Inner Worlders of Inner World. The Inner Worlders built these weapons to be used againest planet Jall, the homeworld of their enemies, the Jallians. The Inner Worlders once could simply bombard Jall with their warships, but after the Ellimist placed an asteroid field in between Jall and Inner World, such a task was foolish as ships would be destroyed by the asteroids. The Inner Worlders eventually solved this problem by creating the Nuclear Mines that could reach Jall without the loss of Inner Worlder troops in the process. While many were destroyed in the asteroid field, at least 700 reached Jall, turning the planet into a nuclear wasteland and wiping out the Jallians who were helpless to defend themselves from the mines.
