Returning to a Modern Fantasy world after two thousand years

Hi, I'm participating in the August prompts writing contest. Please support me by adding this book to your library if you enjoy it! - - - The Empire's of the past. The year was 200 BC and in a world of swords and magic there were humongous empires with incredible power. These incredible forces ruled the lands of the continent, Ronus. The amount of territory they conquered was incomprehensible! The biggest empire that ruled the continent ruled almost a third the entire continent! It wouldn't be an exaggeration to call them invincible—or so you'd think. Despite the incredible power all these nations held, they hid an embarrassing truth from the eyes of everyone. Above the Empire's, were usually the gods. But not in this world. Above the Empire, there was a being. A god on earth. This god reigned from the shadows and controlled every one of the top forces. The reason being was due to its eternal life and immense power. However, one day, without a trace the being disappeared. It had vanished from the sight of the continent. Over two thousand years pass... And the being returned to Earth—bound from the shackles of an ancient temple buried within the earth. But, As a human. "What? I'm a human now? And I lost all my powers?" The old being, now in the modern Ronus, had opened his eyes to a completely different world from two thousand years ago. How did he escape? Why was he shackled? And what mystery veiled his existence. Read to find out! - - - Hope you enjoy my book!
