CLUE!!!

In Blood of Olympus, it is seen in Nico's dream after banishing Bryce Lawrence that Ella the harpy is feeding Cheetos to Seymour (Mr.D's leopard) and recites the following prophecy: The fall of the sun, the final verse

I think this is related to Apollo, as in him turning mortal is the fall of the sun. What do you guys think?
