Parallel Story

Everyone has their own theory of creation but the truth is that the world we know is one of the many that exist and the real creation was the result of a war of light and darkness.
At the current day there is a teenager Harry who has problems at finding friends and adapting to the world around him. Little he knew that the war that caused his world's creation would be directly connected to him and 5 more people around the world. They will find out things about that war and their world that no one knows and realize the shocking truth that they were part of that war and that they are now called to continue it. How would the world around them react at this fight where logic is useless to have?
The species used for the main characters is purely my creation and I ask that no one should use it for their story.
