Elixir Vitae
Alchemy as a secret art has always the main goal to explain the phenomenon of eternal life and achieve immortality. The main object of the search of the alchemists was the philosopher's stone (or Elixir of immortality). This reagent, they believed, allows to transform the substance of one nature into another, ignoble into noble, imperfect into perfect. Besides it could improve and multiply gold. At the same time with transmutation function it gifts immortality. But to obtain the elixir, the alchemist first has to experience death.
