In their search for incriminating proof, Flint and Alexia encounter Mephisto, battle with his mechanical abominations, and investigate the suspicious "Church of the Key". They are eventually detained by Mephisto and taken by sea to Varuna. Flint is thrown overboard, but he survives and reaches the capital to confront Baron Diaz. The Baron threatens Alexia's life and tasks Flint with retrieving three relics in exchange for her safety. Flint is told to enlist the help of the three pirates he had met before: Zeppo, Albert, and Ruby. They assist him in entering the ruins. Flint goes through the ruins and does battle with their ancient guardians to obtain the three relics.
