So I'm running a campaign for the first time since I bought the books (Core, the three Enemies books). One of my players mentions an interest in the Aegis of Contempt talent from Enemies Within, but can't find the prerequisites. So I start trying to help him find those talents. After going through all four books I have not found either Shield of Contempt or Shared Destiny. Is this a mistake, or are these in some sort of adventure that I haven't bought? I thought that aside from the Game Master's Kit and the Forgotten Gods thing those were the only books. Alternatively are they in one of those four books, and I'm just an idiot who keeps missing them (really hoping that's the case)?

They're both Talents from the Inquisitor Elite Advance in the Core Rulebook. Page 89.
