Kamigawa War

Because the Earth emits electromagnetic signals into the universe, the Earth is exposed to other Kamigawa civilizations. Other Kamigawa civilizations send troops to attack the Earth, and the Earth quickly organizes a counterattack. Soon the earth formed a special army to resist. The leaders of this army learned to use the void to compete with the Kamigawa civilization, but leaders of other civilizations would also use the void, and the earth prepared to fight across the universe, and eventually established a protective circle to make the earth disappear into the realm of other civilizations.
