General Thoughts and responses:
re: Talking to the Orb
The Orb has spoken mind-to-mind exactly twice in-series - at the end of
Finder
to Justis, Gurnil, and Ordin - and then at the very end of
Keeper
to Quin. Quin describes the Orb's actions saying "as if it were guiding him (Ordin) to my side." Generally I think Quin is so used to KNOWing so much that she fails to ask some obvious questions. If Ordin doesn't tell HER that the Orb spoke to him (as he tells Justis), then she doesn't question it. (Similarly, she always attributes Kaldill and Daragar knowing her thoughts as being able to read her expression, never noticing their replies are awfully darn accurate, i.e, more like they are reading her thoughts?)
re: The Gate and the Orb
I'm confident that the Orb has some power to control the gate (maybe started out as the GateKeeper as one of it's duties - decides if you end up on Tirilia or "elsewhere".) I also see the Orb acting kind of like a big brother to Quin, including making plans for her without telling her about it. Most likely it was "saving" Quin by sending her through the gate, and also sent her where it decided she "needed" to be next. (Unless one of the Mighty interfered in where she ended up, which would be crappy of them to NOT TELL ANYONE that Quin is still alive.) I also suspect the Orb's actions (i.e. it KNOWs the planet is about to be destroyed) are what triggers Quin KNOWing, which allows her to alert Lissa.
re: Dangerous species
Note - many of those were created by other gods, several of whom later turned out to be among The Hidden. Frex: Quislus regrets creating the Sirenali and the Dark Elemaiya in
Blood Finale
.
re: The Mighty
The One now consists of the Four (Charles, Ashe, Lissa and Hank as Wisdom, Strength, Hope and Wrath), Breanne is still Love and is a seperate entity among the Mighty. Throughout
Keeper, those are always referred to collectively as "The Mighty". (Randomly, I wonder what body part the Mighty Hope and the Mighty Wrath are associated with.)
re: Non-Interference
Exact wording of that part of agreement to join the Gods:
"Should you choose to accept, then you agree to hunt the enemy in all its forms and destroy what you hold the strength to destroy."
"You are held to the normal requirements— no killing of the innocent," The Eye said. "No unnecessary interference. No intentional tampering with timelines."

i know this rule seems fast and loose, but I can also see the original intention behind it, i.e., "All ye gods, ya can't just go and change the lives of all the mortals and disregard their free will whenever it suits you."
