I don't imagine we can just spend an action reading the books and have metaphysics splurged at us, so to learn more I imagine we'll have to use them? First thought that comes to mind us could we substitute an air elemental for an apparition for binding (there are air elementals, right??)?
Elementals don't live naturally, they're created with magic and they don't last that long once the creator stops maintaining them, so the apparition approach won't work with them. I've added this action to the social turn:
[ ] Elementalism
Now that you're sitting on a massive stockpile of magical texts, explore what 'Elementalism' actually is from an inside perspective.
- I imagine the Addaitoh books mention the fact that He escaped to the mortal world (or, well, was taken to the mortal world by Ladrielle). Do they explain what that means? Do the Asur or the Asrai believe that Addaitoh is hanging out in some specific physical place, and if so do they say where that is?
Instead of the place where Gods are, Addaioth went into the world. In some places this is describes as them being physically embodied, in others it's described as more of an animist presence in specific phenomena. One recurring legend says that volcanic eruptions happen because Addaioth is physically inside that volcano and tried to make a sword and it turned out shitty so he's throwing a tantrum.
- As above, but for Hukon. Do the Asur believe they know where He is?
Some parts could be read as saying Tiranoc, though that could be a metaphor.
- Does Addaioth have any symbols/sacred objects/motifs etc. aside from flames?
- If so, do any of them overlap with Dazh's symbolism?
- Also, do either Dazh or Addaioth have any sort of key in their symbolism?
There seems to be no links beyond that of fire and some similar symbols derived from fire. Dazh is fire that warms, Addaioth is fire that hurts. Dazh has a secondary sphere of hospitality, while Addaioth is trying and failing to embody weaponsmithing. Dazh is beautiful, Addaioth is horribly scarred.
- Is there anything about how the the Ellinilli feel about one another? In particular, is there anything saying what Addaioth thinks about Mathlann?
The Asur have a saying derived from the Ellinilli that can be translated as something like 'the enemy of my enemy is not my friend', derived from how dramatically the paths diverged: Mathlann became huge, Drakira is a big deal, Hukon and Estreuth found niches, and Addaioth is sidelined and bitter. None of them seem to treat each other any better for being siblings.
- Now that we have some books on Hashut, is there anything Mathilde can see that could indicate a connection between Him and Morghur and/or The Horned Rat?
- Is there even the slightest hint in the dwarven books that Hashut has some history with the dwarves prior to the Chorfs?
The books seem to claim that Hashut was physically present within the mountains and the Dwarves dug to Him. In some places this was just from trying to dig their way to safety due to the Coming of Chaos making the outside world inhospitable, but in other parts the phrasing seem to imply that they were looking for Him. There's a oft-repeated title of 'Father of Darkness' that rings similarly to Morghur's once title of 'City-Father' and the Horned Rat's 'Under-Father'.
- Do Taal/Rhya/Manann books agree which bodies of water belong to which God, or is it contested?
Ocean is Manann's, but water on earth is hugely contested. Mathilde can spot hints at the conceptual territory that she now knows to be staked out by the 'swamp gods' of the Council of Manhorak, and various lakes, rivers, and related spheres seem to be divided up almost at random amongst the three.
- Is there anything in the books on Manann or in any other of those books that implies that He is, in fact, 'a watery, damp squib of a little God'?
There is a theological argument that can be found that says that when sufficiently far from the ocean, an ant has more power than Manann.
@Boney so what is an elemental, how are they made, and most importantly—can Mathilde attempt to make one, or is she too closely bound to Ulgu to make it work?
The short version is that Earthbound magic taken from a specific medium temporarily retains properties of and a link to that medium which can be used to manipulate it. These properties are lost in the presence of Winds as earthbound magics resonate more strongly with Winds than they do with elements like water or fire, which means that experiments performed by most Wizards and in most College laboratories would inevitably fail.
-Arabyan books on elementals.
-Maybe books on Araby itself, because it's the land that's most relevant to their field of study.
-Going further from that, Arabyan books in general. Since it's the number one place for elementals, the elementalists may be more connected to Araby than any other foreign nation. They'd be more likely to learn Arabyan than Eltharin, Kislevarin, or Khazalid, so why not grab more useful books if they can read them?
No hint of them. The reason why seems to be found insome of the books on Elementals, which describe the Djinn is superficially similar to Elementals, but completely different in practice.
-Books on whatever spirits naiads are, if Forest Spirits doesn't cover them.
They're included in Forest Spirits, under the assumption they seem to be part of the same 'spiritual ecology' as Dryads. Presumably rivers where there aren't nearby forests give rise to something else. Mathilde's categorization isn't meant to be perfect, and there's a lot of places where if she gets a book on something specific she's going to have to reshuffle a lot of shelves to make it work.
-Warpstone. Gut Magic is labelled as Dark Magic, and they're allowed to attend lectures on Waaagh Magic, so they might have books on warpstone. I imagine every organised magical institution has books on warpstone if it's legal for them to have it, or if they're evil.
If they have books on Warpstone, they didn't hand them over to the Grey Wizard.
-Since Geology seems to have gotten broken down into more specific fields like Mineralogy, I guess Pedology might work as a suggestion. It's earth and water, and I'm guessing it's the root of their interest in Rhya. Soil science is known to the Empire, going by Panoramia's talk on the subject.
Hysh is the biggest thing I believe is missing given that it's the wind for stonebending, but, well, that falls under self-evident. Does Hysh not have its associations with stone in DL?
Earth as the Elementalists understand it is closer to Ghyran's soil than Hysh's stone. Their interest in minerals seems to be more an attempt to make dowsing work than it being directly useful to earth elementals.
@Boney, what do elementalists do for a living?
The big money is in being mercenaries and bodyguards, but a lot of them make their living in prosaic applications like helping forges burn hotter or bringing springs up in parched fields. Another common one is in something half way between HVAC and feng shui consultants for larger, more prestigious buildings. Ensuring proper air circulation, a lack of drafts, fires that heat as they're supposed to and don't smoke up rooms, running water to where it's needed, foundations that will stand up to what's asked of them and won't form sinkholes, that sort of thing.
There's a very clear niche for 'knock-off Wizard' that is actually quite positive for society when it means 'something that is useful but there's not enough Wizards to go around', but much less so when it means 'something the actual Wizards swear oaths against'.
