Last week Geek Native posted an article that Paizo was changing the word "phylactery" to "Soul Cage", and that they mentioned such change in the preface of their newest release in their current Adventure Path. Aside from the fact that "Soul Cage" is simply boring, it appears that Paizo is making such change more for getting the credit for doing so instesd of such change being "the right thing to do."
