Meet Potential Church: or, how 99% of problems in the game wouldn't have happened if the Church of Seiros were actual theocrats

(uploaded this before but I originally made it for this essay so you get it again)

Let’s cut right to the chase. The (Central) Church in FE3H often gets accused of being theocrats or whatever, and I have an extremely hot counter-take on this:

If the Church of Seiros was actually theocratic, a majority of things shown in the game and cited by fans as in-universe problems would not have happened.

so like, I'm fairly uneducated when it comes to Celtic mythology or history over all and most of what i know is even more surface level and shallow than the bits i know about Levantine/Mediterranean mythology, so there's that.

BUUUUUT , been thinking about the Saints a bit. IMO as we all know by now, to me they are all Sothis's youngest children. Chichol being the oldest, followed by Macuil, then Indech, and finally Seiros as the youngest baby.

Going by their names, All of them but Seiros are named after figures in Celtic mythology (Needed mention to Saint Cethleann too). I do like the thought that each quartet/set of children of the goddess represent or are named after some classic culture, but the names of the Apostles contradict this, unless they made up names as a disguise. There's also that part which each saint represent a particular thing too....

Also, Macuil canonically being close to Noa?? T_T that's so cute, baby brother who loves magic learning from big sis who also loves magic. But also a big fan of how Noa just used him as an excuse later on in her life after the war, like damn ok I see where Macuil got his bitterness from. Love this for them.

Indech is a bit more obscure too, so it's hard contrasting the due information from internet sources so it means i'll have to read whatever articles or books i can find which i wish i had all the time of the world but life wont allow me to have the slightest break!!!

But apart from that, Indech's a Formorian King (if any of you remember the old art i did of him you see that in some of his modern AU's clothes there's a wink to this) and had at least 2 kids.

Also isn't it funny there was basically smut written of the 3 male saints so the humans could enjoy themselves (Book of Comely saints)

Sadly, Celtic mythos doesn't offer much for cultural or religious syncretism which makes my task harder but not for it less interesting and thrilling lol. I love hyperfixations, and digging deeper research holes.

Much to think about and it's almost 6m and I havent slept one bit. I'll write a bit more on this when I'm more awake and levelheaded and bringing the due bibliography/sources LOL

The Goddess and the Saint

Chapter 7: the one where it's Garland Moon (enough said)

Summary:

Flayn comes back from the Black Eagles' first mission in the Red Canyon, Rhea has Opinions about Seteth's personal grooming, Seteth and Jeralt have a chat on the dock, and Garland Moon flowers abound.

Excerpt:

“Do you not find it a strange development, considering that, per official records, Saint Cethleann was an individual who made friends easily, but was not known for romantic affiliations?”

“...And that can’t change?” Flayn murmured, so soft that Seteth was not sure if she intended for him to hear it. Even so, he almost dropped his spoon. He could feel a headache coming on.

He made a point of setting down his spoon. “Flayn, do not tell me that you have developed feelings for one of these…boys.” His eyes darted around the room, seeking out suspects. Someone from the Black Eagles house, most likely…

“Calm yourself, Brother…” She took another bite of porridge.

“Has one of them confessed to you?”

It IS true that being on here gives you a tumblr accent. This morning my mother asked me something and i replied "i don't know i've never heard these words in that order" and she nearly choked laughing. It wasn't even that funny

at my old job i had a coworker who was tired and made a coffee with like 6 or 8 shots of espresso and i just casually went up to them like “are you trying to meet god?” and not only was this absolutely hilarious to them but they brought it up in future conversations they thought it was so funny but to me this was just as casual as saying “woah that’s a lot of coffee”

Being funny on Tumblr and then going to be funny in real life is like traveling to a foreign country and baby the currency exchange rate is biased in your favor

#calling it an accent is an excellent way to put it

So I've been thinking a lot lately about Sothis and her progeny, if only to give my head a break from the harrowing Christmas season 2025 has thrown at me. Anyway, ever since the new FE3H game got announced, and which I believe to be a prequel and not a sequel for many a reason I shan't go into much detail with here, I've been thinking about IRL cultures that could've possibly inspired her and the Nabateans.

Her name is the Greek version of the goddess Sophdet (personification of the star Sirius etc) and Sophdet herself is, at times, syncretised with Isis and Demeter, as seen below. Yet Zanado has Ziggurats (as seen in the concept art) and aqueducts (ingame battle scenarios) so what gives!!! Now, if if I had to go for any known civilisations that could possibly gather all of these landmarks, I'd say to Ptolemaic Egypt could be my main choice. A place on earth where Greeks, Egyptians, and Romans mixed and matched. Would this explain the Ziggurats? Not really, however, following this lead, we can drift our attention to the legendary and noteworthy Semiramis.

While I don't think my English is good enough to go on and on about her, and the Wikipedia article already does a wonderful job, I'd stay it's a solid lead. As you could've read, she is mostly relevant, adored and talked about throughout a rather considerable portion of classical history. From Assyria to Egypt and then all the way to Libya.

But! I also believe we shouldn't ignore the Minoans with their snake godess and the many peoples of the sea.

This has taken me to take into major consideration the Phoenicians, Etruscas and even Tartessans into consideration more than the own Nabateans, Egyptians or Greeks themselves.

In conclusion? I'm all over the place. More later. I haven't even yet spoken about how 3 of her sons have Celtic names, alas!
