Warning: Very Long Rambly Erratically Capitalised Post Ahead
I'm German by passport, but I only recently moved to Germany and am still learning the ropes when it comes to culture and customs and stuff (people here are a lot more direct than I'm used to and it makes me nervous).
I know what you mean about adjusting to culture and stuff - I spent most of my childhood in West Africa, but I’m Australian by passport. I think it makes it even more tricky adjusting to a culture when it's already supposed to be your culture. There's a weird sense that it's supposed to feel like home, but it doesn't. What region of the world did you live in previously (if you're comfortable sharing that information)? (By the way, I would never have guessed that English is not your first language.)
YES. CS Lewis and all his works have been favorites of mine ever since I had the Chronicles of Narnia as bedtime stories when I was super young - have you read any other of his books?
Yes, I have. I haven't read his theological and autobiographical works, but I've read the Space Trilogy and Screwtape Letters. Narnia is definitely my favourite, though. My parents used to read them to us and when it was my dad's turn he'd fall asleep in the middle of a paragraph. I think I was a bit too young when I read Perelandra and the others because I have only a vague idea of what happened in the stories and I remember being quite confused with how the main character was acting. But I was old enough to know that Venus is uninhabitable… Maybe I should try that trilogy again.
But there are quite a few names and lots of information, and I am still "dense but curious", so I do apologise if any of my follow-up questions are irrelevant/stupid/have technically already been answered.
No need to apologise! I tend to go overboard on the names, anyway. :) And as they say, there's no such thing as a stupid question. :P
Basically, Berad allows Calar to exist because Berad gave the Seven Firstmade (the first humans on Nossi) the freedom of choice and they chose to adopt Calar's ideals. As long as someone values the same stuff he does, he's still around. I haven't seen LoK (though I have seen AtLA and I love it and I'm actually rewatching the series right now) but Berad and Calar don't 'balance' each other - each wants the other eliminated. Calar's power is limited and he is fated to be destroyed at the end of time.
I suppose another question is whether they actively intervene with humanity or if they're more like… symbols?
Whether they intervene or not can depend on the situation. Calar would love to actively unmake all of Berad's creation, but he doesn't have enough power to do that and instead has to persuade or trick people into doing it for him. If people are being destructive without his input, he’s happy to sit back and watch. If they're all being good kids (unlikely), he'll intervene. Berad has power enough to change anything he wants, but chooses to work with humans. However, he doesn't necessarily 'bless' his followers with power, because power corrupts, and all that jazz.
How obvious is it that that these deities exist and how much do they influence the story?
The average person over their lifetime would probably encounter a supernatural being once or twice, and come across an ethereal (a nice one, more often than not) anywhere between once a year and daily, more so in times of trouble or if involved in seriously messed-up stuff (Berad’s ethereals can sometimes show up in these situations, in a ‘guardian angel’ type of role). Before the Mending (I will explain this Important! Capitalised! Term! further down), Berad's envoys would appear to humans in Berad's stead, but since then Berad shows up himself and his envoys remain largely unseen.
Though Berad, Calar and the envoys can change form, they can't (in Berad's case, won't) take the form of an existing person, and there are signs (if you're looking for them) that they're not actually human or animal (e.g., a sort of glow to their skin, no matter what shade; lack of sweat; invulnerability to physical harm; in Berad's case, a combination of magical abilities rather than just one, etc.). If they really wanted to the viewer could dismiss these encounters as random people or creatures, claiming the light was weird or they were tired or it was just a magical illusion.
As for the story I’m writing, I’m not sure yet how, or if, it will be influenced by supernatural beings. Nothing as religiously extreme as the Cult of Calar will feature, that's for sure. At the moment my antagonists are primarily against-the-protagonist types rather than completely-evil-destroy-the-world types that would no doubt attract a lot of unmade ethereals. I've also been working on Marisel's character page and debating whether or not to give her a companion ethereal.
Is that just a lil quirk of his or does it serve a greater purpose/ have a reason behind it/ foreshadow something important?
Berad's missing eye is due to a very Lion-Witch-Wardroby battle between him and Calar at the dawn of the Third Age. (This is the Mending.) (Long story short: he was primarily a user of light magic, which is connected to sight, and one way to hamper the user's magic would be to blind them.)
Oh, one more. You said that Berad is most powerful, but is he all-powerful? If not, then what are his limitations? If so, then that brings back the question of how involved he is and why he chooses to let events unfold as they do.
Yes, he is all-powerful, but he limits himself by allowing humans to make their own choices and face some of the consequences of those choices.
So do the envoys still respond to the worship? How aware are they of they humans and how much do they care?
How did the humans know that there were seven deities but mess up the rest of the information? Do the deities not care that the humans are badly informed?
Before the Second Rift, there was a lot more communication between humans and envoys and most folks lived in a centralised area, so word got around that there were seven and what they were like. Then as folks travelled further from each other, and especially due to fewer appearances from the envoys leading up to the Mending and afterward, the information got mixed up and embellished and changed with changing cultures. The 'seven' part mainly stayed constant due to the fact that the seven Threads of magic are a lot more observable.
Berad's envoys aren't fazed that the humans have things wrong about them because they don't want to be worshipped anyway. They'd care more that the humans don't worship Berad, but that's up to him.
So how were the names from above in Gàldorean if the majority in Gàldorë refers to them by different names?
I think the best way to explain is that one set of names refers to the actual envoys, and the other set refers to the embellished deities in Bittereth. For example, Gwennedir is the actual supernatural being who does Berad's bidding and keeps the weather patterns flowing, but in Bittereth Lili is the wife of the 'top god guy' and the mother of two other deities and she is the goddess of rain, healing and home who will bring health and fair weather to those who revere her and who will strike those who don't with illness or lightning, whichever suits her mood at that moment. Oof, big sentence. So, followers of Bittereth refer to Lili, and (some) monotheistic groups refer to Gwennedir, and they wouldn't say these two names refer to the same entity.
Is it a big deal for a minor ethereal to show up or is it more like "oh hey it's Kevin, haven't seen you in a while"? If one does show up, would the humans recognise them or not?
I laughed at that. I may have to name a minor ethereal Cevèn one day. ;) It's more of a big deal than an everyday occurrence, but some folks would see ethereals pretty often, and probably the same ones, so I can see them giving them names. Ethereals can't alter their form like the more major beings can, so if you saw one often enough you'd be able to recognise it.
Would the Calar cult members try to summon Calar's ethereals?
Short answer: they might try. The thing with Calar's ethereals is that they might turn on the cult members if they chicken out of the evil things they brainstormed to do. There's no guaranteed method of summoning a particular ethereal.
Your description of how ethereals work was pretty near to what I imagined. Their presence does depend on the people, but the more those people frequent a particular place, the more likely those ethereals are to hang around there, even when said nasty people are gone. If someone unsuspecting comes along, they would likely be attacked, although since ethereals cannot take life the unsuspecting person would probably be able to get out of there (unless the ethereals knock them out or restrain them until the cult members return). If someone strongly aligned to Berad and his values came along, there might be an ethereal fight. (Or, knowing that there might be a fight, the unmade ethereal would refuse to show up.)
Some additional worldbuilding - I'm thinking the unmade ethereals are in lots of ways the opposite of the made ones (a bit like how Tolkien's orcs are twisted elves).
I imagine an ethereal aligned with Berad and connected with fire magic being a bit like a semi-corporeal wolf with a kind of a red glow about it and long, wispy fur that looks like it's made of fire and smoke. Its counterpart, aligned with Calar, is still wolf-like in form but more charred-looking with eyes like glowing coals and an aura of swirling ash.
I feel like this was quite rambly and huge and probably very confusing, so sorry in advance for that! Also, you generally haven't asked questions I don't want to answer, just questions I don't have an answer for yet. :P I tend to 'create' the content for some of my answers after you've asked the questions (mostly because you uncover angles and tangents I hadn't considered yet, which is wonderful. Whoever first said that two brains are better than one was on to something. I love your questions) so I hope you don't mind my making this up as I go.
EDIT: Also please don’t think I mean you have to ask questions! If I ramble on about topics that aren’t your cup of tea feel free to let me know. :)
