A Few Drops of Immortality

Exploration Stage: Laboratory
From: Cardsharp
Description: Dear friend, if you continue to search for evidence that the Master travelled to the past, may I be so bold as to give you one piece of advice. Isabelle rightly noted that the Master's speeches are delivered with some delusion of grandeur. I believe taht such a person would have tried to find the famous Philosopher's Stone in the past. Will you try to find the stone in the laboratory?
Completed: Excellent, my friend! You found the famous Philosopher's Stone. It bestowns immortality and turns any metal into gold. Even I would learn to travel to the past just to visit the alchemists of ancient times for such a thing!
