Sacred Swords

Roughly a century ago, the third world war began, this war lead to countless deaths and damages to the world. Countless nations fell and the bloodshed was enough to die the world's oceans red. However, the war ended with none of the countries victory because as the last days of the war came, a new enemy arrived on the battlefield. They killed indiscriminately not leaving anything in their wake. Days after their first appearance, five countries, four islands and an ocean had disappeared from the map, a week after that seven more nations, an archipelago and two oceans had also disappeared. Two weeks after their first appearance the map had lost it's meaning. Civilizations, cultures, legacies, histories all of it was destroyed at the blink of an eye. They then gathered together, in small hives and hardly came out again.
Years after such terrible events, people had started to develop strange abilities, some could fly, some could disappear and some could read minds. A new power for the humans, a new hope of establishing home and life for each other. They once more built towns and homes for each other, slowly on what was left of the world, they once more created nations. However, they appeared yet again, but the humans who had developed special abilities fought against them and they were driven away.
Now, after fifty years since their appearance, the world has found peace and humans have grown in numbers yet again. Those who carry the special power now stand at the forefront of the battle with them... the ones who had become known as the Shadows which threatened to destroy the new life the had built. The ones who have been given the task of fighting them have been named; Lights. The battle for the future of humanity... begins now!
