User blog comment:Cello freak/Should the Kane chronicle's world and Percy Jackson's world exist side by side?/@comment-1636709-20100910230825

In this book universe, I'd say they do exist in the same realm, and perhaps its more of a situation where they "We leave you alone, you leave us alone" sort of thing. I mean, if I were Olympus, I would be trying to keep the house of Life away from them and Camp Half Blood, and I'm sure the Egyptians want to avoid Tartarus.
