Fallen: The Destiny (2007)

Aaron and Azazel defeat the Powers, and force Mazarin and his second-in-command to leave. When the two return, they discover Camael has been released with the help of a rat. Camael returns to Ariel for help. Aaron, Vilma, Gabriel, and Azazel travel up a mountain where the Light Bringer's temple is. Meanwhile, Mazarin is visited by Michael the Archangel, who tells him that if he wishes to defeat the new threat of Azazel, he may have to join with the Redeemer. Mazarin goes to Camael and Ariel, and tells them of Azazel. He then reluctantly agrees to an alliance, and the four set out to find Aaron.
