Obviously, major spoilers ahead!
Ok, so my PCs are (hopefully) going to be wrapping up Book 2 next week. As such, I'm really hoping to do a little foreshadowing/reintroduction of the main adversaries of the Adventure Path: Sangeh and (more important to this post) Pteios. I'm posting here because while the AP has the same "the final villain kind of appears out of left field" issue that many have, it IS foreshadowed...but what I'm missing in this one is the actual motivation of Pteios, his goals and hopes.
Here's how I understand the situation: Pteios has absorbed the mythic power of the warshard, and as such become aware of Sangeh and wants to free her. Sangeh, for her part, is mostly unconsciously guiding him to do so. But I'm not clear on either the consequences of his success or the real motivation for his goals.
Sangeh seems to have been...at best...questionably slain/imprisoned. She tried to stay out of the war between the gods and titans, but was hunted down and attacked by Gorum and Gozreh. Pteios wants to restore her, and this would be bad because...? In Book 2, Amnerion seems to suggest that it's because the gods would more or less automatically attack a risen titan (and kill millions in the process), while in Book 3 there seems to be an implication of Sangeh being dangerous on her own terms because...she'd be so focused on creation that everything would constantly be in flux? (It's not totally clear to me.) Regardless, none of this answers the question of what Pteios thinks should happen, which is sort of alluded to a couple times but never really clarified. Does he think everyone will get mythic power? This seems like a reasonable conclusion given everything that's happening throughout the AP, but again, not really clear. He seems to spread chaos everywhere he goes...but it's not totally clear whether that's intentional. And then, does he want Sangeh restored for a purpose, because he thinks this mythic madness would be a good thing? Does he view it as a kind of cosmic justice, given her original attempt at neutrality? Or does he just feel he owes her a debt and is willing to do anything to repay it?
Please help me out if anyone has better reading comprehension than I do; I'm really feeling a bit lost, and I'd like to start highlighting Pteios's background machinations!
