Is a prologue needed for this story?

I am posting an opening story, but before that I’d love to have some feedback on this prologue. I am a beginner, and I know that the story isn’t well written.<br>As I am trying for a fantasy in first person storytelling, I am not sure if the prologue is needed and if it is needed how to write it.<br>My only goal is to write a prologue that sets the story, but most importantly compromises the reader to buy the whole series and read the story to the end. I’m begging you to be ruthless in your comment. Thank you.<br><br>**A Prologue of The Unseen Enemy**<br><br>Death was not new to me. I witnessed it constantly throughout my life; however, this day was different. The day that changed everything; my life and my destiny.<br><br>As I stood beside my father’s body, I could have sworn that his spirit was smiling at me. How could a father leave his only daughter behind? What was his most precious wish? How could a father leave his daughter behind? What was his most precious wish?<br><br>The day before his death, he told me that he had lost the war and that his defeat could only be undone by me. He told me that I have a destiny to fulfill and that this war will end only upon my victory.<br><br>What could I do? How could I undo his defeat? I was only a child. I had not yet turned 14 years old.<br><br>This war had been raging for years and years. My father had lost; his defeat could only be undone by me. It could only end upon my victory. How could I do it? How could I win the war that my father had lost?<br><br>I was only a child. How could a child win a war? I had no idea. I was in shock, but as more people surrounded us, begging me to take them to safety, I knew I had to be a grown up, like my father. How could I let my father down? How could I fail him?<br><br>This day was the day that changed my life. It changed my destiny. I had to leave everything that I knew behind and start a new life. I came to learn that life is not a never-ending story. Life is short; therefore, I had to take advantage of it. I had to pursue my dream.<br><br>I had to pursue my dream. I have no idea how to do it. All I knew was that I had to undo my father’s defeat. He had lost; I had to win the war.<br><br>At that time, I knew nothing of the war; yet, I had to undo my father’s defeat. It was too much for a teenager to bear. I had to grow up quickly. I grew up quickly, only to find the war that my father had lost, was not a war. It was not a war between countries or states. It was not a war for land or power. What was it? How could I win it?<br><br>*** <br><br>Is this prologue needed? Is the message clear? <br><br>As I am a beginner, I know that the story is bad and most likely will be rewritten as I gain more experience and knowledge. The story is most likely to change, but what I am mostly concerned now is compromises the reader in the first read. I want to compromise the reader to complete the whole series, and I want to do that in the first read. How can I do that?
