Thanks!

Totally unrelated to your comment, I am curious what your thoughts are on the whole "speaking Latin summons demons" thing... That seems to be one of those cliches that's really stood the test of time. The only reason I can think of is, a few thousand years ago Latin was what English is in modern times, a commonly-used language for trade because the economic powers of the day used Latin, so that's what the demons use? Yet you'd expect some demons to speak Greek, or Hebrew, or Arabic, or to keep with the times, or to have some sort of psychic ability to understand what whoever is summoning them is saying regardless of language...

At least Lord Dominicus has an excuse--last time he was around this part of the galaxy, Latin is what most of the humans he encountered were speaking. Although, there is something about the idea of him being fully fluent in modern, slang-heavy Internet American English I find quite amusing, an ancient cosmic entity using words like "yeet" when casting fireballs and then saying "it's lit, fam" as he walks away from a burning crater seems very on-brand for him.
And we thought it was bad when the old folks called every video game device a "Nintendo" back in the day...

Joke's on you, my parents didn't want to spend any of their cigarette money on video games for me when I was growing up!
I did spend a lot of time playing outside, though, and drawing, and reading, and building with Lego and whatnot. My grandparents were responsible for a great deal of my upbringing in the first decade or so of my life. Probably explains why I am the way I am now. Maybe I'll write a memoir sometime.
"I was born at a very young age..."

I suppose another contributing factor to the cliche could simply be the cultural dominance of Christianity in Europe and the various lands they imported it to over the past 1000 or so years. Then again, I would still be surprised if they all spoke Latin, as many of the "demons" in Christianity are just the deities of other religions--see "Beelzebub", a childish pun on the name of a Canaanite god ("Baal Zevul", meaning something to the effect of "Exalted Lord"), the "Lord of Flies" being a reference to how dung attracts flies. So, basically, it's a fancier way of saying "your god is shit lol", I suppose.
As for why so many villains in American media have British accents, the only one that really comes to mind is Star Wars, and I suppose I always chalked that up to how those accents sound very authoritative and formal, the sort of thing you'd expect from a massive military empire.

Anyways, when it comes to anything Biblical, I tend to think of it more as ideas and fables than anything that was ever meant to be taken 100% literally, I don't really hold it as any more or less "sacred" than any other ancient religion or myth.

I realized that my in-universe theology is broken. If Dominicus is my god-mode avatar in-universe, he's somehow both God and the Son of God, making him Space Jesus, however blasphemous that notion may be. Yet other aspects of him seem more like Zeus, especially the whole "likes to sleep with the mortals" thing. I've also used a couple Dungeons and Dragons alignment quizzes friends have linked to me, and by answering the questions as I figure Dominicus would, have determined he is somehow Neutral Good despite being Space Lucifer.
Also, in what I can only describe as a stroke of accidental brilliance (as in, I have no idea how I bullshitted this together this way but I'm going to claim it was intentional), it seems like "Lucifer Dominicus" is a very, very sloppy Latin translation of "The Lord's Lightbearer". I quite like that. His apprentice, Lucifer Apollon, the blonde pretty one... THAT'S the clearly evil one.

Funnily enough, all of this started because I got super into Ghost and felt like designing a non-canon "Satan" character, but then it all just sorta fell together. While that one-off "I felt like drawing Satan" design became Apollon/Abaddon, my attempt to redo the concept and create myself a proper Satan (in relationship to myself as "God", really laying the blasphemy on heavily now) resulted in Lucifer, who somehow wound up being a character that could be considered a "good guy", or at the very least, some sort of anti-villain. Maybe I'll just convert Apollon into my Satan and reveal he has a "true form" that looks a bit more like me than I should be comfortable with--and since I find manipulative behavior and "being fake" and being "two-faced" to be very distasteful, it would be even more fitting. Maybe in reality he's not that beautiful, elegant, blonde-haired pretty boy Archangel Micheal looking space antelope after all... but you can't really convince the humans of your divine status as an angel of light looking like a fat hairy Space Yak like Dominicus, can you?

Lego is one of those toys that, while a somewhat pricey initial investment, has near-infinite entertainment value. Unfortunately, after my mom passed away a decade ago, my Lego and I had to part ways, but my younger siblings still have them. I am sort of sad that among that massive collection was the Millennium Falcon set my mom gave me for Christmas a month before she died, I really should have held on to the Star Wars stuff for myself but since my youngest brother was an even bigger fan of both Star Wars and Lego than I was, I figured he'd appreciate them more than I would.
If you like Lego and want a video game with the same near-infinite entertainment value, spend a few bucks on Minecraft. Best 27 bucks I ever spent (entertainment-wise).

I think I rambled at length about my thoughts on religion as a whole before, so it probably comes as little surprise that I'd view Christianity as just another mythology to pick some ideas from. In what might come as a bit of a surprise twist, while I had looked into it in the past, it wasn't until I started getting interested in Satanism/Luciferianism that I really started to think about the Bible and many of the ideas within. It is interesting to look at it as a collection of fables, stories meant to convey lessons rather than some sort of historical account, and think about what value can be taken from them from even a secular, nonreligious perspective. If anything, this has given me a bit more respect for religion as a whole than I held previously, because I've come to an understanding that some things about it are pretty universally human, even if a lot of it is influenced by the cultures the religions were shaped by.
Anyways, I now sort of like the idea of warping how some of the biblical stories fit into my own universe as having to do with the dynamic between Dominicus and Apollon, especially if any tale about kings demanding children be killed could be tied back to Apollon wanting to be sure Dominicus has no heirs left behind that might come back to overthrow him.

That said, I really do need to figure out at least some basic aspects of Lucifer culture, and explain why a group of highly advanced Old Ones would just sorta fade from the universe. I do get the feeling that their arrogance is a major contributing factor, but I also think I should leave most aspects of it vague and mysterious for plot convenience, the occasional artifact or derelict spacecraft of small Luciferian holdout or enclave world popping up here and there and offering little lore tidbits (and, of course, a justifiable, plot-convenient ancient and potentially overpowered tool, weapon, or spaceship).

As for whether that's a summoning circle on his butt... that's just some generic pentagram to be edgy. That did get me thinking about whether or not some sort of summoning-circle-like things could be tied to ancient alien tech as well, though, and primitive sapient beings like ancient humans may have not understood the technological aspects but merely noticed the seemingly magical outcomes of the use of these circles and their associated patterns. I suppose a possible comparison could be made to the "cargo cults" that arose in the South Pacific after World War II, a theme I do find interesting and did briefly consider playing with in regards to a few different aspects of the universe over the years.
While the crop circle phenomenon has been proven to be a hoax at this point, I suppose that could be another useful comparison for what I'm imagining here, the idea that these geometric patterns could be used to convey information to spacecraft or something along those lines. How would ancient humans interpret a tractor beam or some sort of teleportation or Star Trek-esque "transporter" placing an object in a circle? If they didn't understand that the runes and patterns that made up the circle were for a ship's sensors to make necessary calibrations or something to that effect or that there might actually be some sort of technology under or around the actual circle, the idea that the circle itself has some magical properties might seem plausible. The natives may think those runes are the ancient unspeakable names of demonic entities, whereas to the aliens that drew them, they basically mean "safe to land here".

As for what people can be convinced of... I live in the United States, and have for the past 30+ years--if you think my ramblings about Space Yaks get overwhelming, you do NOT want me getting political!

That's fine, if you ever want to come back to this with some more in-depth discussion I'll check back eventually...

Now that you mention it, Stonehenge does sorta look like some sort of landing platform one could dock some sort of saucer-like craft atop or within!
