IDEA ABOUT THE PROPHECY!!! [sorry if this has already been pointed out]

An oath to keep with a final breath

That could mean Nico's promise (an oath) to lead the other 5 to the House of Hades. '''[that's the part I think has already been said. The following I can't find on here, but that doen't mean someone hasn't already said it]''' Following on from that, the 'final breath' would be refering to the fact that someone may/may not (most probably WILL) have to stay behind in Tartarus; it being their 'final breath'.

Once again, sorry if someone else pointed that out, I just wanted to say my opinion. :)
