The Labyrinth was a test crafted by the Goddess, an unending and deadly place filled with worlds inside of worlds which threatend to devour any who entered.  Many of the people who had tried to pass through to the final floor never even came close, a large amount failing on the earliest floors. One soul fought his way through and managed to reach the final realm, facing off against the final trial and barely succeeding.  In the end his life was the cost for that, and with a final breath he accepted the end of his life with dignity and grace. Then he woke up.
