Theresa's Note is presented to the Hero if they choose the Wealth card after defeating Lucien during the Retribution quest in Fable II. The ultimate reward is 1,000,000 Gold (this is the exact amount of gold needed to purchase Fairfax Castle).
Letter Contents Edit
The note reads:
The wealth you wished for awaits you in the Chamber of Fate. It was there you discovered your true nature. It is only fitting that you should find your ultimate reward there as well.
