With all four Sacred Crowns, Anubis is able to summon Osiris, another god who reveals he and Set were once a single form named Ra. Set, however, became greedy and stole power from Osiris to take over Egypt. Osiris uses the last of his power to transport Sphinx past the defenses of The Castle of Uruk, where he challenges Set for the fate of all Egypt. Set takes on his "true form"; a hideous monster with immense power, but Sphinx is able to defeat him. Set is not destroyed, indeed Imhotep appears and tells Sphinx that this is not in his destiny. Instead, Osiris arrives and forcibly reunites himself with the weakened Set and Ra is formed once again. Ra gives the Mummy the last Canopic Vase, but the Mummy tragically falls and breaks it. The game ends with a cliffhanger as Imhotep states there may be other ways to help Tutenkhamen regain his human form.
