So we know how Enclave feels about other Vhaeraunites, Lolthites, Eilistraeeans, but does she have any particular opinions about followers of other gods?
From the gods and religions she has the most opinions on to the least, starting with the Dark Seldarine:
Kiaransalee and her followers:
Does not like her, but probably not for the reason you think she doesn't. Enclave is a character who has strong opinions about death and what should be done with bodies of the dead. She's not against necromancy of convenience (This was actually discussed recently as a topic elsewhere, and the concept of raising a body from the dead to have it move itself elsewhere isn't particularly chilling to her - That's just a matter of convenience) and her opinion on the undead as a concept is far more nuanced then hating them as a lump-sum (Ie; She's unbothered by liches, ghosts, shadows, vampires. Anything that's undead through personal choice, or circumstance of their own existence does not bother her. But things like raised skeletons and zombies she's like. ENOUGH. Enough. Is it not enough that they were torn apart in life, you have to disrespect their bodies in death?)
Anyway. This became more about Enclaves feelings on the undead, so let's get back on track.
She doesn't like Kiaransalee's followers because she views them all as scorned ex-Lolth worshipers still willing to use the bodies of fallen drow as tools until there's nothing there left to use.* This is also an issue she would have with Lolth worshipers doing the same, but this is like. Core to Kiaransalee's religious doctrine. Enclave thinks everyone deserves proper burial rites, and for their bodies to be left alone once they've died.
The irony of this is that I think of all the underdark gods, Kiaransalee is also the one that could have most easily gotten to Enclave had she been around at the right place and time. Enclave's own motivation for coming into Vhaeraun's church came from a larger desire for revenge against Lolth and her clergy, and so the core of what strokes that desire is easily something that could have been manipulated and reinforced by the right people.
She's never met the goddess herself, but I think in any au in which she does she ends up feeling rather negatively. She'd view her as short sighted and pathetic, like a dog biting at the heels of something stronger than it (Lolth.) I think she has very little sympathy for "Salt the earth" styles of revenge - Enclave, despite herself, believes the revenge one takes must ultimately be productive to the larger whole (at least where she is now.) So no burning entire cities for her.
*Note: This is an opinion that might become more extreme in the foreseeable future, depending on how Realmsbound handles Kiaransalee, her followers, and their conflict with House Jaelre. I plan on pushing her through the Dalelands when that comes out, and her opinion might be tilted in a different direction by circumstance.
Ghaundaur and his followers:
She views him and his followers to be as much of a threat as Lolth is, but one that is not and should not be their current concern, outside of where he and his people are actively targeting them. The way she sees it, he is a god who, despite his association with the Dark Seldarine, has appeal towards and is able to convince surface races to indulge in his worship, which makes him far more of a long term threat than Lolth. But she also understands that he and his followers, unlike Kiaransalee and her followers, are a VERY effective counterweight for Lolth. His clergy is one of the few that can actually rival hers in explicit combat.
In a way, her current stance on it is "enemy of my enemy is my friend" But she also knows that it's an enemy that will not only quickly delight to turn on them, but will do so on a whim.
Not unlike Kiaransalee, there is a world in which He Got Her as a follower. The main dogma he operates under - (All creatures have their place, and all are fit to wield power. Those who hunt weed out the weak and strengthen the stock of all. Those who rebel or who walk apart find new ways and try new things and do most to advance their races. Creatures of power best house the energy of life, which Ghaunadaur reveres and represents.) Cuts INCREDIBLY close to the dogma Enclave's original church prioritized, to the point that I have in the past considered that Enclave's mother's original house did have connections to his church. That's not canon yet though, that's a passing thought I'm letting you have. Now adays, with the mindset she has as an actualized person, she thinks his followers are all like. Sociopaths. She does not buy into a proper survival of the fittest mindset anymore.
I also think her opinion on him as an individual is one that would change with time and her own change as a person. She like. She's able to wrap her head around this god being a thing older than almost anything else on this world, and the way that could warp and change a being. She thinks that the one thing that makes him less of a threat to be dealt with then Lolth is that he has no long term desire to destroy and toy with people. He's a force of nature that is hungry, and desires to feed, and it happens that THEY are what he is happiest to feed on. He is an enemy to them because the nature of his existence forces it to be, which is less insulting to her than Lolth "For shits and giggles" the goddess who torments them because she's bored.
but it would take her a while to get to that second opinion, and long after the timeframe of any immediate canon.
Selvetarm and his followers:
I've always made the joke that Enclave as a character was built in a way where she doesn't know what a Drizzt is, but DOES know what a Selvetarm is. This is true of all of the gods that I'm mentioning here, by the way. Enclave has way more knowledge and lived experience with the gods of the Dark Seldarine as people THROUGH Vhaeraun, and intentionally so. I suppose a bit late to establish the full extent of that, but yknow.
I think it's one of the area's that she feels a bit of cognitive dissonance for Vhaeraun's personal feelings on him (She feels a bit sorry for the young god, and doesn't understand Vhaeraun's larger irritation towards his son as an individual, and feels like the irritation might be something short-sighted, and strictly emotion-driven.
She just also figures it's not really her place to challenge Vhaeraun on that thought, because like. Well she wouldn't want people challenging HER about her thoughts on her dumbass kids, and he doesn't hold the death of her kids against her. So....)
On the other hand, she thinks his followers are some of the dumbest fucking people in the world and would rather not be fighting with any individual one of them.*
Now. It also, slightly, depends on how they're worshiping him. If they come from a group thats worshiping Lolth through him? Well at that point you're just a Lolth worshiper with a different coat of paint.
If you're worshiping him separate from Lolth..? Hmm. Morally neutral act, the judgement of which relies heavily on how your clergy behaves and what your individual clergies long term end goal is. If she had the chance to snoop around and figure out the whole of his clergies deal (something, as you must understand, very few people in the realms WOULD know) she would be interested in those that want to free him from Lolth's control. Objectively speaking (and why she views Vhaeraun's personal anger towards his son as something short-sighted) freeing Selvetarm from Lolth's immediate command would be like hitting Lolth in the kneecaps. It wouldn't be an immediate cut to the power and influence she has in the realms, but it WOULD be beneficial to have a fourth counter weight that hates her specifically.
*Note: This is ALSO an opinion that might become more extreme in the foreseeable future, depending on how Realmsbound handles him and his followers and their presence in the Dalelands.
Various other gods and their worshipers that she's developed opinions on over the years, from serious to joking. It's worth saying that unlike the Dark Seldarine, she has not met with and does not directly know most of the gods themselves, and so her opinion is case by case basis on their clergy and individual.
Corellon and his followers (and honestly largely anyone in the Seldarine):
On one hand... Like that's the Evil Asshole who is fine leaving all of them to die. His clergy and the extended Seldarine have given them and any settlement they've attempted to build over the years so many problems, it's hard not to have every negative feeling she has towards them reaffirmed. She knows now adays that it's more complicated than that, larger propoganda efforts, they should move to work with elves to better their lot, blahblah.....
On the other-hand (and this is an opinion I've had her voice before). She doesn't actually think Corellon is a long term threat to them and theirs anymore, at least to the extent Lolth is. The elves and their influence on Toril is one that is actively dying, and it's due to nothing but the choices that they as an individual community of people made. Many Vhaeraunite communities (and, begrudging to her, Eilistraee's) communities are finally able to take place in spite of their attempts to continue to whisper about the Evils Of Drow, because they ran away when they realized they actually had to consider human opinions.
To Enclave (perhaps incorrectly, though she's shielded from that incorrect nature) this is a problem taking care of itself, at least in this immediate sphere. The humans are going to stop listening to those pretty gold elves when they realize how quickly those elves will abandon them, or when they realize the only people actually willing to give them any answers on the elven history they crave to know are the drow they'd been told to shun.
On the other hand (pt. 3), them not being a long term issue doesn't change that things like Seiveril's Crusade are an immediate concern for them in the NOW. But she thinks they just need to play defensive, and win a war of attrition.
Severash and his followers:
Tone of being hissed under her breath, "Ugh, these fucking losers again." She's absolutely had to deal with this guy and his followers, and probably will need to do-so again in the foreseeable future. I think she gets more irritated at them then she does the general concept of Lolth or Corellon. Bringing them up and she's immediately placing her head in her hands with a migraine.
Used to be entirely neutral on them but through Ilphaer, Enclave knows that her clergy helped wipe out a good portion of Vhaeraun's in Sshamath. As such, they are on her shit-list.
That's the extent to her opinions of them. She has not directly had to deal with them outside of individual worshipers, and so she does not have long term thoughts and feelings on them.
Mystra and her worshipers:
Stomping her feet. Why the hell are they always in peoples business? If she never had to see another Chosen of Mystra again, it would be a too soon. Arrogant, annoying, Wizards are so annoying.
True over generalizations being made, opinions could be changed depending on individual interactions:
Lathander, Bahamut, Helm, ect:
Any god that tends to have clergies that attract people that hold very grandiose ideas of good and evil tend to be clergies that she views very poorly. In her mind, at their best they tend to be patronizing and miserable to be around, not fully understanding the full extent to which circumstance creates evil. At their worst, they actively justify the slaughter of her people for the crime of being born evil, and are a larger threat to any meaningful social order.
Silvanus, Umberlee, Mielikki, Chauntea, Lurue, ect (Category: Nature gods): Completely and wholly neutral on them. They are people you pray to so that the world doesn't die.
Ilmater & Talona: Putting their money where their mouth is. Neutral leaning positive.
She doesn't know who Keptolo is because I cut close to canon about him being barred from the realm, but in mega OC au's where he would be a factor, or in the world where she does discover him and his followers, she holds similar opinions to his clergy that she does the Selvetarm followers who worship Lolth through him. Kind of pathetic behavior. Though, unlike Selvetarms worshipers which are like, ghoulishly ridiculous as soldiers, the platonic ideal of a Keptolo worshiper (of which I think is echoed in characters she does enjoy like Beltrin) COULD get under Enclave's skin. Selvetarms clergy are a bunch of solider-types that are a bit in over her head, but the kind of charm that a Keptolo follower cultivates either activates her red flag OR kinda sweeps her off her feet, and theres no inbetween.
