No, Kaeya is not the Prince of Khaenri'ah; his family, the Alberich Clan, were regents who served the throne, but they weren't royalty themselves, though he carries the destiny and secrets of a fallen nation, with lore suggesting he's a descendant of a significant Khaenri'ahn figure and potentially an heir to a new dynasty or linked to the Abyss Order, rather than direct royalty from the old regime.
He is a prince. His grandfather (or his father, could be either) is the heroic king of Khaenri'ah. Dainsleif may recognize Kaeya. Istaroth most likely has a hand in Kaeya's story as well.
Prince of Khaenri'ah Kaeya is a pretty popular headcanon amongst the fandom, so I wanted to compile a list of evidence supporting it! Previously, Kaeya's passive talent was named 'Heart of the Abyss'. It was changed in one of the updates, however, to be named 'Glacial Heart', presumably to avoid the obvious spoilers.
Kaeya's family, the Alberich Clan, became the Regents of Khaenri'ah after the cataclysm. It is unclear how many generations passed between Kaeya and the cataclysm; it is also unclear why Kaeya is unaffected by the curse.
With King Irmin as the ruler of Khaenri'ah there were 5 other people that hold quite the reputation within the nation the 5 sinners. According to the recent events in Natlan and the confrontation of Capitano and Ronova, the 5 sinners and King Irmin were responsible for the problems Khaenri'ah caused for everyone.
There isn't one single "rarest" 5-star character, as rarity changes with player count and banner availability, but Diluc, Jean, Qiqi, Keqing, and Mona (the Standard Banner characters) are often cited as rare because they're always available and hard to get specifically, while limited event characters become rare when their banners haven't rerun in a long time, like early releases such as Venti or Klee for newer players. Some players consider characters with very few reruns, like early limited units, to be the rarest.
Both Kaeya and Diluc were shocked by what they had witnessed, losing the calm composure a knight should retain. "Even someone like Master Crepus would submit to such a dangerous and evil power..." Sinister thoughts flashed through Kaeya's mind, and he simply smirked: "This world is truly...
So long story short I've seen some people in the other Genshin groups arguing that Kaeya is the Khaenriah's missing King and the last descendant of the Eclipse Dynasty when it was already revealed that Kaeya was in fact a descendant of Chlothar of the Alberich Dynasty, the infamous founder of the Abyss Order until it ...
Khaenri'ah was a nation without a god — not because it had a god that died or abandoned them, but because it never had a god to begin with. It was a powerful nation, built purely by humans, an unprecedented flourishing and glorious civilization — it was the pride of humankind.
That night, Kaeya revealed his true identity to Diluc — he was a secret agent from Khaenri'ah, who was planted in Mondstadt, as “last hope.” This led to a life or death confrontation between the two which ended with Kaeya receiving his Vision.
Yes, Genshin Impact features characters who are canonically LGBTQ+, or heavily queer-coded through lore, dialogue, and events, with examples including Jeht being a lesbian and Venti being canonically non-binary, alongside many player interpretations of characters like Chongyun/Xingqiu or Ningguang/Beidou, though developer miHoYo often avoids explicit romantic confirmations for playable characters to maintain broader appeal.
Dainsleif was a royal guard and Kaeya is implied to be a descendent from there. This could mean that Dainsleif knows of or was once acquainted with Kaeya's ancestry, or perhaps even Kaeya himself. This seems to be the main reason people theorize they are connected.
The 4 Pillars are Gold=Alchemy,“The Wise”=Irminsul/Fate, “The Foul= Beastmaster Knight”, and “Racher of Solnari”=“Hunter of the Moon, Avenging the Sun”.
Fans notice that for the flirty dialogue after defeating Dvalin, Kaeya's dialogue does not change based on which twin you choose. This led to the idea that Kaeya is bisexual, also supported by his flirtatiousness to Sara (female) and Albedo (male).
The Traveler is a quasi-deity of trickery and joy worshiped by Jester Lavorre.
Despite the curse of immortality placed on him by Ronova, Dainsleif appears much like any normal person would compared to others, such as Capitano, who also suffered from the curse and had a more advanced state of decay. This is due to a ring gifted to him by his elder brother, which resets his condition.
If I remember right, Kaeya is only a halfling that was born after the cataclysm, that's why he isn't immortal and not a hilichurl either.
Yes, right after Kaeya admitted to being a spy, Diluc attacked him and struck his right eye, cutting off his eyepatch and revealing a fully functional eye, albeit now with a crude mark due to his previous attack.
Kaeya is disliked because he's smug and his character quest is essentially him abusing you to do his job while also making fun of you by leading you around the map and lying to you. People don't like that, because pretty much everyone else in the game treats you like you're special. Kaeya doesn't care though.
if crepus had adopted kaeya, diluc would have become automatically his brother, yet kaeya still calls him yixiong (sworn older brother) and calls crepus yifu in dialogue.
Kaeya, a character from Genshin Impact, is speculated to have romantic interests in both Sara and Albedo, indicating a bisexual orientation. There are also discussions about his complex relationship with Diluc, suggesting a deep bond that has been strained over time.
He is a self-proclaimed "anti-hero with an attitude problem;" as long as everything ends the way he wants, Kaeya does not care about the methods used.
