There was one think I’m kind of surprised they didn’t include, ambassadors between camps. They exist within Camp Jupiter’s structure with Nico being an ambassador for Pluto, so it’s not that far off to have ambassadors between camps. I could see the Roman ambassador living in the Big House with a couple of Roman guards and the Greek ambassador living somewhere in New Rome with a couple of Greek guards. I can see it happening, maybe after the situation with the emperors they can start to have ambassadors.
