The Esper Saga
The Magi War
Unlike The Kardus War, the Magi War wasn’t fought against the Kardus or for the sake of Magi alone; rather, the war broke out between the nation-states of Terra, vying for supremacy in a world lacking any central power. It was a savage war, involving almost every major nation: Trakonia, Fuuka, The Savage Land, and many others. The Kardus were not involved at first, since it was not their mission to get involved in politics.
Eventually, however, it became clear to the Kardus that this was not a war of spears and swords – it earned the name the Magi War even as it happened, as each nation developed more and more advanced and dangerous magitech. Still, the Kardus knew that they did not want to make enemies of Terra, lest the leaders of the world would rise against them, and kill them.
After many months of debate, Alexius took action, endeavoring to bring an end to the Magi War. Four of the other Kardus joined him. After a long and brutal struggle, the war eventually came to an end, and Terra was united once more under a common banner. The Kardus created a temporary parliament meant to rule the world, and appointed Alexius their leader. What followed was a brief era known as the The Age of the Empire.
