I think you should work on your grammar. It hurts reading the prologue and I can't read past your first chapter. I'm not asking for a perfect grammar, but a readable grammar + sentence structure. That is the minimum you need when writing a story.
Don't try to be extraordinary here. Most stories on this site are pretty generic with really basic plots, and they are coincidentally the ones which have the most success. On the other hand, uniqueness is rarely rewarded.
Rather then focus on uniqueness I would focus on passion. Write about a world and characters you, yourself are excited to explore. Don't worry so much about public opinion, or what is 'common' or not. You may not be the most read. But an author's worst enemy isn't the audience; but rather it is themselves. The most important thing a writer can have is a prolific spirit. Look at any renowned author and you will find they never stop writing. So passion (and schedule) is important.
What you are asking should be an internal question. What is important or interesting to you? I for example; love to come up with characters that occupy grey areas of morality and use the world to explore relationships between ethics, perception, and reality. I wish I could give you an easy simple answer. Every plot under the sun has been written. So my advice is focus on being yourself and find your true voice.
Focus on how you write your history.
People don't really care about if a story is original or not.
Make reading the story pleasurable. The prime example is the book "The name of the wind" that is not original, but the way that story is written is fantastic and appealing.
