It is said that the Alchemist discovered the Elixir of Life-a drop of precious essence so potent that if one were to mix it with water and drink it, they would live forever. Rumor has it that the alchemist who discovered the essence secretly lived for thousands of years, disguising himself as a different person in every lifetime so that no one would ever discover his true identity. The only thing that never changed was a large but faint birthmark, about the size of a fist, on the left side of his upper arm. Throughout history, kings and royal families longed to find the alchemist using this only clue exhausting their resources without any luck. Some believed that the alchemist had become various rulers of kingdoms in far-off lands, quietly building empires throughout history.
