The Messenger departs from that holy land beloved by the tripartite prophecy, splitting herself into a thousand pieces and setting off on her journey.

O Tribios, Holy Maidens of Janusopolis, the Chrysos Heir who stole Passage's Coreflame. You shall toil for the masses, bringing the news of deliverance to all domains — Go find the children of humanity with golden blood in their veins, shatter the dimmest dark in this world, and walk toward the tomorrow where the stars gleam.
