Edward and Alphonse continue their quest for the Philosopher's Stone, the ultimate alchemical treasure. The stone's formula may be found in the catacombs of the central library ... if the mysterious figures named Lust and Gluttony don't get there first.

As young boys, Edward & Alphonse Elric dabbled in alchemy to try to resurrect their dead mother. As a result, Ed lost one arm and one leg, while Al lost his entire body and had his spirit sealed into a suit of armor. Now, they are searching for the fabled Philosopher's Stone to restore what they've lost.
