One of the most famous achievements in alchemy would be the Philosopher’s Stone. According to legend, the Philosopher’s Stone could prolong life to the point of acquiring immortality and transmutating base metals into silver or gold. With the Philosopher’s Stone, one could attain an endless lifespan and potentially limitless wealth. The process of creating the stone is a mystery and has many interpretations. I am thinking of including something similar to the Philosopher’s Stone in my fantasy series. I will be drawing inspiration from Fullmetal Alchemist and The Dark Crystal.
