We know that they are beastmen of a sort. We know that only a select few can see them, and even fewer can understand them. We know that they have some sort of hierarchy. We know they only stay in the Black Shroud. They also, apparently, spoke on behalf of the Elezen of Gelmorra in order to gain them passage to the Twelveswood (I read that somewhere, but can't remember where. Feel free to correct me.)
However...so many of these things are inconsistent. NPCs talk to and about moogles all the time. Moogles interact with objects (non-Legacy opening cart ride, for example) but other people never see what they do. The moogles also talk of helping those of Eorzea in their time of need (the beginning of the Seventh Umbral Era), but if only a few can see, interact with, etc. with them, just how do they help? Are they a game mechanic only in that regard? Did the devs forsake continuity in favor of reviving the Mog Net? The Padjal were the ones that asked the moogles for help, which they only did very begrudgingly.
Do the moogles have a sort of glamour that they use to deceive others? What is it about certain people, making them "special" (according to the moogles), allows them to see the moogles? And just why are they so darn happy about being potentially endagered?!
They have also been seen in the service of Padjal. White Mage quest NPC Raya-O-Senna is seen ordering her moogle acquaintances around, even inciting fear in them.
Now let's talk about Good King Moggle Mog XII. According to game legend, he, and all the other moogles, resided in another realm before migrating to Eorzea after a terrible war. What that war was, and who it was against, is unknown...I think. He was left behind in that realm after helping his moogle followers to Eorzea, but was summoned here using the same method the beast tribes use to summon their Primals. Does this mean he is a Primal himself? Is this other realm the same realm the consciousnesses of the Primals resides in? If that's so....did the moogle fight a war with the Primals? Why don't the moogles need to constantly feed on aether...or do they already?!
This makes my brain squiggle a bit. If we assume the moogles have been in Eorzea for a long while, how is King Moggle Mog XII still alive? The moogles refuse to crown a successor in honor of him. So unless moogles have a ridiculously long lifespan (spanning multiple Eras), I don't see how he isn't a Primal. That would make the moogles, by extension, beings of aether, similar to plasmoids....right?
PERSONAL SPECULATION AHEAD
I dunno, man. I think he's a Primal. He even tempered his followers. Kupdi Koop is uncharacteristically fierce for a moogle....I also think the moogles secretly hoard crystals and consume them. The bard quest line mentions the moogles hoarding Soul of the Bard crystals. Granted, they were doing so in order to selfishly preserve the bardic tradition, but it still sort of serves my point.
However, I don't think they malevolently consume. I think there might be some sort of...for lack of a better term...Aether Cycle going on, in which the actions of the moogles actually perpetuate aether, despite having consumed it. Hence the hoarding of Soul Crystals.
The rest of the inconsistencies....I dunno. I'd be, admittedly, a little miffed if there was such an inglorious oversight in such a staple of the Final Fantasy series.
So...what's your take? What do you think is up with the moogles?
Also...how much do I have wrong or have I mistaken?
