What is each Scion/Archon's specialty?

[Eloah]

I'm sure the information has been mentioned in passing, but it's a bit difficult to recall exactly when each was discussed. So I'm curious if people remember what each Scion/Archon's specialty was/is? Like I know the one that's touched upon most is Thancred, with his specialty being in Espionage. I believe Y'shtola's is History, and Alisaie mentioned hers and Alphinaud's were in practical uses; combat and daily use respectively. And we know Tataru is a financial genius. But what about everyone else's? This is mostly for the Sharlayan Scions, but I'll include Tataru because she's earned it, lol.

Here is a list so as to not just state everyone in game, lol.
Thancred, Y'shtola, Urianger, Alphinaud, Alisaie, Tataru, Krile, Papalymo, (the real) Yda, Meonbryda, G'raha Tia, Louisoix, and any other Sharlayans we might know of.

It's buried on like page 1,000 by now but we had just a really brief exchange about this question last year:

Based on their Encyclopaedia Eorzea entries, their fields of expertise go something like this:

• Fourchenault Levailleur - something magical, probably, but he could possibly also be an expert on "learning"
• G'raha Tia - specifically interested in the Allagan Royal Eye, which would probably require studies in Allagan history
• Louisoix - Ancient prophecies
• Krile - Healing magicks, probably?
• Matoya - Aetherology
• Moenbryda - Aetherology
• Papalymo - Arcane studies
• Rammbroes - Anthropogeography
• Thancred - Survival and intelligence gathering (spycraft)
• Urianger - Prophecy
• Yda - Hand-to-hand combat
• Y'shtola - Arcane arts

Kesey mentions Mikoto below. The Encyclopaedia Eorzea II indicates her extensive achievements in aetherology.

Personally I'm hoping that Alisaie can start building an Archon thesis out of

what she's learned about tempering and the novel treatments she/we have been rolling out

Wait why the list is so long.
G'raha, Krile, Matoya, Moenbryda, Fourchenault are Scion?
(Never heard of Rammbroes, he's in ShB?)

And lol why would a scion specialized in hand-to-hand combat. Yda (Lyse) wasn't a real member.
She was more like an orphan raised by the Scion.

Some of the people you named are Scions, yes. The ones that aren't are still Archons, which are a separate class of people, which many of the featured Scions are in addition to being Scions. Archons are scholars who have, among other things, published an Archon thesis, analogous to a real world Ph.D. dissertation, and have been recognized as sages of their fields. Anyone with the funny R tattoo is an Archon, and the tattoo is their ID for getting access to sections of Sharlayan libraries that contain knowledge that could be considered dangerous in the hands of non-experts.

(Never heard of Rammbroes, he's in ShB?)

You have met Rammbroes. He's the Roegadyn in charge of St Coinach's Find in Mor Dhona, the camp to the east of Revenant's Toll. His tattoo is notable for being white rather than red, and on top of his head.

And lol why would a scion specialized in hand-to-hand combat.

lol why would anyone specialize in how to kick ass and not get their ass kicked
There are real world people who train their whole lives to master combat arts, and why wouldn't an organization whose goal is to prevent the destruction of the world keep at least one of those around?

Yda (Lyse) wasn't a real member.
She was more like an orphan raised by the Scion.

You're mistaken about Yda on two accounts. First,

Yda, the real Yda, wasn't a Scion at all, as died before the formation of the Scions of the Seventh Dawn; she was, however, a member of the Circle of Knowing, one of the two groups that later merged to become the Scions.

But second,

her studies in Sharlayan and mastery of her field definitely did earn her Archon status well before her death, as she did have real Archon tattoos. This is why Papalymo had to glamour fake ones onto Lyse when she took up Yda's identity.

This makes me wonder if the player character is going to become an Archon by the end of Endwalker.

Well, we are going to Sharlayan so that's where we would get said title. But i don't see Fourchenault just granting it like that to us.
Even if we as WoL are by right of the stars and will of fate exceptional at every department.

Not right away, but by the end of EW? Maybe. I could see there being some way to get Archon as a title at some point.

While I would love some more tattoos, and being recognized as a sage of some field, I don't see how this is something they could implement in a sensible and believable way. As mentioned before, Archon is the in universe equivalent of a real world Ph.D. G'raha talked briefly about his Archon thesis in one of the patch story quests and basically every Archon we know including Rammbroes made a point to describe long hours of study and research. For the WoX to earn Archon would require a lot of off screen abstraction of a process that takes real world people four to seven years to complete. I would not buy that we could earn it in the course of one expansion story. Maybe if it were a long spanning side story that took from 6.1 all the way to 9.0, I'd believe it; even then, the time span of those expansions may be too short for it to be anything but an "honorary" status.
