It is written in the Book of Poe:

    After the Creation, the cruel god Fortunato rebelled against the authority
    of Montressor the Creator. Fortunato stole from Montressor the most
    powerful of all the artifacts of the gods, the Cask of Amontillado, and he
    hid it in the dark cavities of the Palazzo, the Catacombs, where he now
    lurks, and bides his time. 

Your god Poe seeks to possess the Cask, and with it to gain deserved ascendance
over the other gods.

You, a newly trained Mason, have been heralded from birth as the instrument of
Poe. You are destined to recover the Amontillado for your deity, or die in the
attempt. Your hour of destiny has come. For the love of God, Montressor: Yes!
For the love of God!
