Elixir of life

The elixer of life is an alchemical potion that supposedly grands its consumer eternal life, the formulae of which has been long sought after by alchemists.

In the early 15th century, the French alchemist Nicholas Flamel reportedly created an elixer of life in his secret laboratory in the tunnels beneath Paris, which remained hidden there under the protection of a group of monks. It was retrieved by the Assassin Arno Dorian at some point during the French Revolution on the request of Marie Anne Lenormand, to whom he passed on the elixer.

In 1567, the Jiajing Emperor of China ingested a lethal dosage of mercury, orchestrated by the Assassins, believing it to be the elixer of life.
