I do not understand how an Astrologian does its Magic.

[Okamimaru]

I think it's less to do with the individual stars and more the configuration of stars.... since the sun isn't part of a visible constellation it would be almost impossible to know what you'd be drawing up spell wise let alone being able to access it... therefore the sun wouldn't have any effect either way... the constellations are still there during the day even when not visible (the AST would know this and it's position in the sky even when not visible)

[Sylvain]

Not odd at all, really. It's only relatively recently in human history that we've discovered that stars are just faraway suns. Prior to that, it was believed that they were totally different types of celestial objects. A fantasy universe like this one can go with whichever interpretation it likes.

Well yeah I know that but that's not exactly what I went for, since they are the same object, if there power was truly coming from this source, then the whole diurn/nocturnal shouldn't work as nocturnal would simply be a weak diurnal.

But we see that it is not the case obviously, so shouldnt it instead means that they get the energy from a different source, weither it is the actual source.
Does it even have to be the star? It's not because they believe they get their energy from the star that this is actually the case, Does it matter that much that their energy comes from the star or not? As long as they do get energy to manipulate, the source shouldn't matter much. Also, there's been case of people using magic without really understanding where they got it from or how it worked. The WHM quest for instance shows that some people can manipulate magic without specifically understanding how it works.

Afterall, magic in FF14 is very "physical and scientific" as it is part of the natural world and manipulating ether/magic is something any living being seem to be able to achieve, so it is unconscious and natural to some degree. Ether manipulation is a natural phenomena in FF14. (Unlike FF15 for instance where it needs to be granted, but once you can access it, it seems to be a very natural thing to do, like, just thought manifestation)
For instance, if they strongly believes stars are different entities, shouldn't the different nature of the magic they use depends more on their perception instead of what it truly is, a bit like how they still predict event based on a moon that doesn't exist and wasn't really a moon. The fact that it worked (without them exactly knowing why), imo, points toward the fact that it only works because they strongly believe it does, they basically make the magic works through sheer will power and faith.
And we know how strong will power and faith can be as a form of magic manipulation/manifestation in FF14.

However, it IS stated that Midgardsormr carried his brood to Hydaelyn from another star, I believe, which implies that it is known in the game that the sun is also a star... Or perhaps, the planet is. In this cosmology, it could easily be the case that the sun is not a humongous ball of nuclear gas, but instead a small, but very warm object also in orbit around Hydaelyn. (Think of how the sun is portrayed in the Discworld series of books.) So, the stars we see in the sky are other planets like Hydaelyn, visible because they also have tiny bright suns spinning around them.

Everyone knows it? I didn't know her words were vastly known on this even by scholar.
Regarding the nature of the star, I agree it doesnt have to be a ball of plasma dealing nuclear reaction at its core, and anyway, can we even say something such as nuclear reaction exist in FF14? Everything, including living beings, are made of ether, and ether seems to follow different rules than atoms when it comes to physical phenomena. Personally, I've always seen the sun in FF14 as a huge chunk of fire Ether floating

Even in the tiny sun case, though, your question is still unanswered: Why couldn't AST get more star power from the sun, an incredibly nearby star? There's a couple of explanations. Perhaps they DO - but star power does not dilute over distance.

Well that'd be odd because most magical phenomena do seem to dissipate over distance, like, you know, how our fields / light source do. Like, many times magical phenomenom did have a range, so it would be very very odd that this doesn't such a basic rule.

There are many possible explanations - and the game itself hints at pretty much none of them. Probably never will, either, as delving into this kind of nitty-gritty is a great way to get your lore tangled up over time. :P

Well this is why I suppose that they don't actually get it from the star.
The fact that a great part of their art worked based on a lie (a false moon thought to be a true celestial object) implies that these object do not hold any power.
If something as important as a moon (which wasn't an actual moon but a man made object) can disapear without perturbing the magic they use, (and we can't say "it doesnt affect it because it wasnt a true moon, since their set of belief was based on that, and it worked based on that) then I suppose that if a constellation vanishes, the rule should hold.

[Shadotterdan]

I think that it's less the stars and more the constellations, which in Eorzea might be a little more tangible than in real life with a power all their own. Secondly, even though Dalamud was a false moon, from a fortune telling perspective that doesn't matter too much. Mankind intruded on the heavens and left their mark there, but it's presence still has an effect on the pattern of the sky. I think some of you guys are applying far too much science to this and forgetting that in Eorzea, it might just be that the bullshit people used to believe about astrology actually works here.

[BillyKaplan]

Dalamud falling shouldn't matter. It still had mass and affected things like the tide and created eclipses. Even its fall doesn't matter as other stars disappear as well. If a star and turned into a black hole, relying on it until that moment would still count.

Their magic IS about constellations. The <50 quests are all about attuning to the six Lower Heavens, each representing two out of the Twelve. To simplify gameplay you have all cards right away, but that's the gist of it. I agree it makes sense it should be stronger during nighttime, but the world is still exposed to the stars and their influence. So long as you've attuned, it doesn't matter.
Re: Healing, I like Allyrion's take on it. You alter the fate so they weren't hurt as badly. Regen is a series of such small alterations. Nocturnal sect is proactive - you create a protection against future damage, not changing what came to be, but what will occur - similar to how you can put a card in your Spread.

tl;dr ASTs are monsters and I love the class so ♥

[LineageRazor]

I doubt Dalamud was massive enough to have any kind of noticeable effect on the tides. It was a mighty small celestial body, likely no larger than a moderately-sized town. Remember that Bahamut took up most of its interior, and he was small enough that his hand was only the size of a battle arena.

And that's assuming that the tides are even CAUSED by gravity in this fantasy universe!

[silverlunarfox]

I really like the Class, game-wise, but Lore-wise, I just don't get it. Help?

One Word:

Yu-Gi-Oh

:P

Gods be good - you look fantastic with that hair cut, lil' Lala!

That bein' said, you're like a walkin' Eorzean Encyclopaedia! If anyone needs t' know summat, you're the one t' turn to. Been at you're shite for years an' still dependable!
