Ok, let's discuss this new prophecy:

Apollo faces death in Tarquin’s Tomb unless the doorway to the soundless god is opened by Bellona's Daughter 

Tarquin and Reyna are obviously going to play a role in the next book. Now about the soundless god, I found online that Harpocrates is the god of silence, but is somewhat associated with Egypt like Serapis.
