Egi Appearance

[finiteHP]

I'm def interested with what you can do with them instead of what they look like or what they're called. I'm also understanding that Carbuncle will come im many different colors! Is this true or just a concept?

Your theory is also consistent with what the Sylphs had to say. They always said that the scaled-ones and feathered-ones were not violent until after they called the Primals. Another thing, though, is that the Primal summons require large amounts of crystals to summon them. The official page says "In times immemorial, there lived mages who had not only the power to summon the primals, but also the means to transmute the primals' essences, thus binding them to their will." So transmute means to change the nature of something, and then they bind it to their will. So my line of thought is Summoners must acquire a fraction of the Primal's power, which they can then command.

Let's also think about weapon choices here... Traditionally in summoning mythologies, you see summoning circles, or patches on the ground made for summoning creatures. We start to see them appearing in X, but they also show up a lot after X. Let's assume that in XIV, the Summoning Circles don't magically appear as part of the spells (The Beast Tribes seem to like summoning in specific places and have what's needed for ceremonies out ahead of time). The books provide easily mobile summoning circles, and probably lesser consumption of summoning resources (Magic, crystals) which would explain a smaller size, and incomplete summon. I like to think though, what's being summoned is just their essence, which is then bound to a catalyst like a crystal, giving them shape.

Or, perhaps more likely, binding them to our own aether/soul to sustain them. If the transmutation was to say, align the primals essence from ambient aether absorption to a specific type of aether, in this case, ours, it would then become a dependency type of situation. If the primal wishes to exist, it does our bidding, as we're giving it the sustenance it needs to exist at all in our world.

To note, Arcanist magic IS heavily dependant on geometrical shapes. That's been told to me in an Alchemist quest where you need to make a grimoire.
They really depend on special geometrical patterns drawn in enchanted paint, that is why they carry books full of them for more ease than requiring creation of those on the spot, also why grimoires are written with enchanted ink of various types, from silver-based ink to plant-based.

ALSO the usage of Egi... According to Fantasia it means 'To do, drive, lead', or to 'pass or spend time' in Latin... You know, saying "Ifrit Egi" would pretty much be the same as saying "Ifrit Driven" or "Ifrit Led", which is exactly where I think they went the "Powered by" sense of 'driven by'.

Of course i'm not sure if latin works that way but, it makes sense

That makes the most sense out of any explanation of the word's usage I've come across; the pet being "driven by" the power of the relative Primal, tapping into its power, and not actually channelling from the Primal directly.

In a way I can kind of imagine the SMN pets being a kind of empty vessel, and that vessel only takes form once you've called upon the power of the Primal to 'complete' it. In a sense the pet could potentially be the same creature in every Egi state, but it's just being imbued with the essence of a different Primal whenever its summoned.

Egi is the first-person singular active indicative of ago.

Ago can mean a lot more than is listed in this thread so far, including the to manage, to guide, to govern, to put forth, or to arouse (as in stir-up or conjure).

I think that makes perfect sense.
