The Labyrinth of Desires

Gold which can buy countries. A lifespan which will never expire. All these things desired by humanity can be obtained in the Labyrinth, and more. Of course, not without the risk of death. Billions have chosen to 'Descend'. Yet, to date, less than four earned the prizes they sought at the very beginning. One day, an amnesiac wakes up in this dangerous place. The only thing which guides him is the single sentence he awakens to: "The past lies at the bottom." (Note: This is also being written on RoyalRoad)
