I, first thought this god can be Janus. (Yes, he isn't tecnically a god, but still, he is a god) Since, we met with him in the Labyrinth, and Janus is god of the 'doorways' and archways, he is also an important god for the Romans. which, in the next book we will see the Roman demigods so maybe Janus will be appear in the next book. For 'soundless god', i don't now but, maybe it means that something happened to Janus so he became soundless.

Okay, last thing was a crap. But, somehow Janus fits the story. Maybe Apollo will meet with him, and then he has to make an important choice (Janus is also god of the choices), maybe Apollo has to decide to do something, and that thing maybe will the last important choice that he has to make.
