User blog comment:SayuriDarling/The Crown of Ptolemy Official Discussion/@comment-25044056-20150401234142

first of all, why exactly is there a barbie background on this wiki? will somebody please explain this to me!

At first I wasn't sure if I should be disapointed with the Crown of Ptolemy or not. I assumed if this was RR's last Percy Jackson/Kane Chronicles crossover that he would cram as much Greco-Egyptian stuff into it as possible. Instead the story didn't introduce any new elements of Hellenistic Egyptian mythology and kept the story focused on the battle with Setne as much as possible. I guess I'm cool with that.

The whole Percy getting posssed thing seemed kind of fan-ficy to me though.

Setne successfully recreates the Crown of Ptolemy, by uniting the crowns of Wadjet the cobra of lower egypt and Nekhbut the vulture of upper Egypt. But after he's defeated the goddesses leave the crown behind to test the heroes and see what they'd do with it. Carter takes it back to the 1st nome but admits it's not 100% safe there.

He says this power is tempting and others will want it. Carter also says that even if they keep the crown safe others may try hybrid magic and the more it's tired the more damage will be done to reality. For this reason they have to keep the coexistence of greek and egyptian pantheons a secret
