Deep in my heart I yearned to be a player in tales of adventure, but I have buried this selfish desire with the obligation I have put upon myself to my fellow man. So, I decided to dedicate my time, my effort, my LIFE to my work in the hopes that I would be of help to my fellow man. But in a twist of fate the people I wished to help have turned on me. This left me broken with a hole in my mind and heart, but my resolve would not waver. Like every failure from before, I began to pick up the shattered pieces of myself and attempted to put myself back together, but suddenly I am reminded of what I truly wanted. ADVENTURE. To see the world and experience all that I could. Be it through fear, cold, or even nightmarish hardships. I WILL HAVE AN ADVENTURE. These 5 words rang out in my subconscious and with-it fate had turned, and I now find myself in an unknown place, my memories fractured, and my body changed? "WHERE THE HELL AM I?!" Now in an unknown world and with very few memories. Our protagonist will venture forth to find himself. The time it will take, what will occur, and even how will he be changed are all questions that run behind every tale. But interestingly, other tales run in parallel with him. They will cross paths and sparks will fly as numerous as the stars.
