So many things in being mentioned here that I’ve wondered about!
1. I agree that some of the talk of “celestials” might be a holdover from 3.5 campaign, and that is one of the reasons why I asked the question in the first place. To see if any of these things still exist, and if so, in what form. In the previous campaign there were summoning spells, and you could summon celestials. Today summoning is much more restricted, and almost the only things summonable are fiends. There is one divine spell to summon a guardian angel, which is therefor pretty obviously affiliated with the PoM.
2. This led into the question about whether there is anything besides fiends and PoM representatives that could be summoned – i.e. benign outsiders that for simplicity I am calling celestials. Because servants of the PoM don’t seem to be the flip side of fiends. There are many more fiends (we believe) and they are unaffiliated with a god (we believe). They are so prolific that they are scooped up in industrial amounts by Sarish and never seem to diminish. So why are all the unaffiliated outsiders evil? I'm wondering if I already answered that for myself - that all the non-evil would have seen the light that helping the PoM was in their own best interest, and thus would be aligned with them and thus part of the PoM now. But that's just me rationalizing. We've seen that the PoM has nonhuman worshippers on other planes, and possibly on Onara (deep ones for Yarris?) so why not entire legions of servants out there we are unaware of as well.
3. As for servants of the PoM, what are they? Obviously Valinor are complex, either being a fragment of a god’s divinity or shaped in reflection of it. It is as possible they are constructs as independent outsiders – especially since they generally evaporate upon death. But other servants seem to exist, but aren’t explained either, despite them being potentially more accessable to humans. Veil Maiden’s are a great example. Are they outsiders, spirits, shades, or something else? Possible people with souls, who died to because shades and were converted in heaven into spirits? How complex can this get?
4. I ask this because it leads into a lot of the questions about souls and spirits, and what is what. We know beltine’s followers are the experts on shades. But shaman’s are the experts on spirits. Both of those fall under knowledge religion right now. Are the spirits of the “Bane of Chendo” (or whatever their name was) bound by Beltine’s church now shades, or spirits? Is there a link between the two, and if so, what is it? In “For the Lesser Gods” there appear to be spirit servants of the PoM present, and a link between shamans and gods, but now all shaman are essentially forced to be outside the PoM. People appear to have souls, which can become shades, but I believe we refer to the “soul” of an Elorii as a spirit. I’m very interested in where these lines intersect.
5. The question about the celestial giants mentioned above is one I’ve wondered about as well. Obviously on Onara they are bound by the PoM, but apparently elsewhere they aren’t. That does make a very interesting question about what happens to the souls of those elsewhere, and what used to happen to their souls before they tied themselves to the PoM. This is especially true since the new history section of the blessed lands book seems to indicate that the Ssethregorans found it necessary to have divine magic to open gates – gates that we believe the celestial giants were the technological source of. If their gates required divine magic to use, who supplied that when the celestial giants (and cyclops) used them? Were the celestial giants celestial enough to use them without a god’s help? Or was there a PoG (pantheon of giants) that we haven’t seen any sign of? And if so, I expect they’re not too happy with what the PoM has done to the dwarves… (I consider this highly unlikely)
