That's silly, of course it's all real! It makes total sense that a T-Rex, a Ninja, and all of their pals go around writing down and distributing world history in the form of a game. And I'm really a Gnoll from Varisia. You can trust me, it's ALL real!
Except for Santa.
Hakotep convinced the morally dubious Kitsune Necromancer to side with him, so he got to live. On the Necromancer's turn, he Quickened a Horrid Wilting with his rod , and then Spell Perfection empowered a Canopic Conversion. 249 Damage and a bunch of failed saves later, Hakotep had a new general and some new mummy Lieutenants.
I think that had DSP not done Pathfinder compatible "traditional" psionics (with the pointsies and the sciences and whatnot), I would have definitely wanted Paizo to do it. (It? Them? I don't know, I'm tired) But because all of what DSP did does exist, and is really good, and is widely known and accepted, Occult magic is a good way to make something similar and not step on toes.
Also, who knows? Maybe someday we will get to see Arcane and Divine and Occult and Psionics as their own well defined mechanical subsystems of magic. *cough* Abilities, sorry.
