Series Interactions



Percy Jackson and the Olympians series and Heroes of Olympus series, collectively known as the Camp Half-Blood series, are two series of books written by Rick Riordan. It is hinted that it exists alongside the Kane Chronicles world. In the third book Sadie's mother hints that there will be more adventures for the Kanes in the future dealing with Setne, rival magic, and other gods.

Relationship with Kane Chronicles
The series makes occasional references to the Camp Half-Blood series, as it takes place in the same world.

The Red Pyramid
In the epilogue of the graphic novel, Sadie is seen wearing a Camp Half-Blood T-shirt.
 * Amos states that Manhattan has its own set of gods and that they must be kept separate from Egyptian gods. He says this while looking at the Empire State Building, the current home of Mount Olympus.
 * Thoth makes a vague reference to the Percy Jackson and the Olympians series when he mentions Hermes, who he states is nothing like him. This hints that he as seen Hermes and that the Greek and Egyptian gods might interact. This statement, however, might not be reasonable if he is inside a host, since the host isn't him. If this is the case, he might be comparing their true forms. He may not have a host, which would more resonable as he should he able to inhabit a place of learning in his true form like Anubis can in a place of death.
 * Anubis seems to have the same appearance as Nico di Angelo from the Camp Half-Blood Series. Coincidentally they have the same nickname, "Death Boy".

The Throne of Fire

 * Carter catches a glimpse of a winged horse flying around Manhattan, and recalls what Amos said about Manhattan and its gods. The horse may have been Blackjack while Percy was following Zoe in The Titan's Curse.
 * Carter makes another allusion to Percy Jackson, when he's drowning and wishing he had sea god powers.
 * The Roman ghosts that appeared later in the story mentioned the Roman gods Jupiter, Pluto, and Vulcan. Later, when they were destroyed by Ptah, he mentioned they went on to whatever afterlife awaits them, referring to the Underworld.

The Serpent's Shadow
Notice: ''Before the Serpent's Shadow, there was no hard evidence that the Kane Chronicles existed alongside the Heroes of Olympus world, with the modern Egyptians existing hidden underneath the skin of the Greeks from the eyes of Rome. In the book, Rick Riordan left a note reading 'final ending', but has not confirmed if this is the final ending of the Kane Chronicles, or the entirety of the Kane story.''
 * Lacy and Drew from Camp Half-Blood make an apearance at a school dance that Sadie attends and mention they go to a summer camp together and Drew is a tyrant there as well as at school.
 * Sadie's mom claims there will be other Gods and rival magic Sadie and Carter will encounter in the future since the Egyptian Gods have temporarily retreated.
 * Anubis explains to Sadie that in the world of the Gods (i.e., both the Camp Half-blood series and the Kane Chronicles) that a person who dies and goes to the Underworld, they go to the one they believe in. ex: if a believer is mummified, yet believes in the Greco-Roman Underworld, they will go to Hades'/Pluto's Underworld.
 * At the end of the book Sadie says that there haven unidentified magical energy coming from Long Island. Camp Half-Blood is on Long Island.
 * Rick Riordan left the book on a note that read 'final ending', but there might be another appearance of the Kanes in future books he writes.

Future Crossovers?
When asked in a recent Q&A session in Maine, during the tour for The Throne of Fire, author Rick Riordan was asked whether he would ever do a crossover series with the Kanes and Percy’s world. His answer was:


 * "I don’t know. It’s an interesting idea, but for now I think it’s best to keep the worlds separate to avoid utter confusion. Again, so many ideas, but each one takes a long time to write!"

However, The Son of Sobek is a future short story featuring both Percy Jackson and Carter Kane, with the audiobook narrated by Rick Riordan himself.

Trivia

 * If the worlds of Percy Jackson and the Kane Chronicles collide, the Egyptians would be the second other set of gods that Camp Half-Blood meet.
