Forge of Virtue was an expansion pack that adds a quest to Ultima VII in which the Avatar must pass a series of tests to revalidate himself in the three principles of Truth, Love, and Courage, and destroy the last remnants of Exodus. With the expansion, an earthquake takes place at the beginning of the game. After speaking to Lord British about the tremors, the player will be given free use of a ship called The Golden Ankh, and can visit the Isle of Fire to begin the expansion subquests. The Isle of Fire was previously the site of Castle Exodus in Ultima III, and reappears only during this game. The main plot of the subquests involves destroying the Dark Core, which contains the last remnants of Exodus. In order to do so, the Avatar must obtain three talismans of Truth, Love and Courage, by passing their respective tests.
