Diary of the fallen conqueror

I entered my underground base it was in ruins it feels like its been thousands of years, I went deeper in and explored my ruined base then I arrive at the entrance of my throne room I opened the large doors and found my lifeless body with lifeless golden eyes, majestic self, in a black suit and cloak with long black hair tied by a red ribbon and slim body brimming with aura so terrifying I even tremble even knowing its me. I was confused "if that's me then, who am I?" I ask myself that time I was confused maybe right now you are too. well anyways It was holding on a book, the title was barely visible but written there is "For my Master's return". I read it for a couple of hours and at that moment everything was clear to me. I died.
