So, not gonna lie, I've had about a liter of nihonshu. With the greater share of my pre-Endwalkers achievements/desires done, I've not much else to do but think and ruminate.
A line has always bothered me/stuck out to me/begged me to overthink it.
Leading up to our final confrontation with Hades, he makes the quip, "Fool. Who are you? No one. Nothing. Once I have reclaimed my heritage, my first act will be to expunge your stain from history's weave."
Emet-selch/Hades averts his eyes. He cannot look at you while he says this.
My world will have no need for heroes.
So, if you know these lines in another language, then please, tell me what differs. Especially if you know them in Japanese. I want to know what context was possibly lost in translation, or what possible loopholes localization cleverly used to get the lip sync a little more accurate.
Anyroad, my line of thinking follows thus: Emet-selch is Older Brother Coded.
1. He's old. That's made abundantly clear.
2. He shows a favoritism towards the WoL. This could be for many reasons, but the subtext reads that it is personal. Hades seems to be at odds with not just the WoL being presently set against him, but against the very core ideals that the WoL holds... i.e. Heroism. It reminds me of one of my older brothers who has differing philosophical/political/social views from my own.
3. The average player picks a fairly short character, whereas Emet-selch is tall. Hence, most people will always be looking up to him, in and between cutscenes.
4. In my experience, brothers have the fiercest personal conflicts. Whenever my brothers and I have fought, we have held nothing back. This sort of conflict has had a few trope-like things throughout history. Namely Cain and Abel from Abrahamic Religions, as well as the rivalry between Zeus, Hades, and Poseidon.
5. Emet-selch's true name is Hades. I have an, admittedly personal, belief that Azem's true name was Poseidon(or something relational like Neptune or Pontus). This is mostly related to the fact that the WoL's aetherial signature is Blue Aether. The first Blue Mage spell the WoL easily learns is Water Cannon from a young Kraken. Poseidon was also the god of horses and earthquakes(not just the sea). Horses in myth represent many things, but chief among them are: power, heroism, independence, nobleness, and triumph. Poseidon is also the younger of the two, between Hades and himself. However, since Lahabrea is said to have made the pegasi, that is attributed to Poseidon, so it leaves room that Azem may have been Zeus. Zeus is the youngest of the three.
6. "Oath of Blood, Born from Blood, or our Fallen Brothers. Time stands still. Oaths fulfilled, now we run for freedom!" <- approximate lyrics from Endwalkers theme trailer music. Perhaps it's just my addled brain speaking, but SE always did seem to favor metaphors that took on a literal meaning on top of their symbolic ones. There's a word for that, but I'm too drunk to look it up.
7. I reckon that Emet-selch's hatred of heroes arises from his sense of duty to the orderly society that his people generated, on top of his inferiority complex in regards to his brother and more particularly, his brother's methods. I feel as though, try as Emet-selch might, time and time again he tried to prevail with the methods he and society loved, only to see Azem smash them to pieces and stand triumphant over them, not merely grandstanding as the Scions do (though they follow). However, I assume that the one time Emet-selch was right, was when the Convocation and Azem had their difference, and so doing, doomed Azem. In this way, Emet's disgust for heroes is not actually with heroes, but with the fact that the greatest hero he ever knew needed him, and for pettiness's sake he was not there for him. I also reckon that the voiceover we here in the Endwalker trailer, which is Emet-selch speaking, will be found in a holo-recording in the Mare Lamentorum.
We don't have anything concrete, of course, but it's something that's stuck in my brain since 5.0.
If anything, could any other lore enthusiast, or any lore forum peruser that happens to care and know, let me know if the line about, "reclaiming my heritage." is radically different in other languages?
