Character Details

Kaeya is an adopted son to the Ragnvindr Family, the renowned tycoon in winery. It has been a long time since he last called Diluc Ragnvindr "brother." Kaeya currently serves as the Cavalry Captain of the Knights of Favonius, trusted by Jean. Kaeya is often the one cleaning or wrapping things up in every incident occurred in the vicinity of Mondstadt.

Character Story 1

What's more interesting is that your best chance of finding Kaeya is not at the Knights' headquarters, but at taverns at night. Kaeya is often seen sitting at the bar, gossiping with other denizens and sipping the famed Death After Noon of Mondstadt. He is surprisingly popular among the pensioners of Mondstadt, even earning the title "most suitable grandson-in-law candidate."

It's hard to imagine someone as mischievous, amiable, and wine-loving as Kaeya as being the Cavalry Captain of the Knights of Favonius. Both hunters and bandits alike are often among Kaeya's drinking buddies. As weary of him as they may initially be, they all eventually find themselves victim of his smooth talking, telling him all he wants to know. Depending on what they then make privy to Kaeya, their night can turn into anything from an uncontrollable nightmare to a harmless night of banter. 

"Everyone's got a secret, but not everyone knows what to do with it."

Says Kaeya, with his usual arrogant smirk.

Character Story 2

"Justice is not an absolute principle, but is the result of striking that fine balance between strength and strategy. As for the details of how it's done... Don't worry yourself too much about that."

Kaeya once said these words in front of Grand Master Varka. As long as everything falls into place the way he expects in the end, Kaeya doesn't care all that much about the means. This cavalier attitude is what defines his character. Not so unlike Death After Noon's wild and explosive taste, one might add.

However, his reckless approach to things is not uncontroversial. Once, in order to force a bandit leader into facing him directly, Kaeya triggered the guards of an ancient ruins to cut his opponent off, putting his own men at risk in the process. It's times like these when even Jean, who puts a lot of trust in Kaeya, finds herself shaking her head in disapproval. Not that this bothers Kaeya, of course. On the contrary, he actually enjoys putting people into the difficult position of making tough decisions. He takes pleasure in seeing the hesitation in his comrades' eyes in the moment just before they dive into battle with him, just as he takes pleasure in the look of fear in his enemies' eyes as they face off against him.

Character Story 3

The prosperous winery business has long since brought wealth to Mondstadt. Prosperity begets greed, and greed draws in bandits and monsters. The scourge that loiters in the shadows festers with complexity, each within it having their own reason for gathering in Mondstadt. Kaeya defends Mondstadt from this threat not only with his sword, but also with his smarts and wit.

A young knight dedicated years of his life to studying the threats in and around Mondstadt, and reached an astounding conclusion: The seasons when the famous Death After Noon cocktail is not available, the threat levels and incident reports both inside and outside the city show a drastic decrease, until Death After Noon once again becomes available... The young knight showed his findings to Cavalry Captain Kaeya in hopes of getting some advice from him.

"Interesting. I'll look into it." Kaeya answered, with an obscure smirk on his face

Character Story 4

Generally speaking, Kaeya is easy to talk to and nice to have a conversation with. The only matter that he sheds no light on is his past. Even when the Grand Master demands information on his backgrounds, Kaeya glides over the answers with only vague details.

"It was an afternoon near the end of summer a decade ago; my father and I passed by Dawn Winery."

"'I'll go get us some grape juice for the road.' He said, but he never came back."

"If Master Crepus hadn't taken me in, I doubt I'd have made it through the storm that night."

The matter-of-fact description hides a carefully constructed lie. Kaeya has never once spoken the truth about what happened that afternoon: 

"This is your chance. You are our last hope."

His biological father squeezed his lean shoulders, but his look stretched through Kaeya, to some place far beyond. On the other side of the horizon, sat their distant homeland of Khaenri'ah. Kaeya would never forget that look, intertwined with both hopefulness and hatred.

Character Story 5

Many denizens still remember the two most eye-catching young gentlemen in all of Mondstadt. One of them was the impeccable Diluc, an elegant swordsman who always wore a friendly smile on his confident face. The other gentleman was the eccentric Kaeya. He was Diluc's friend, support, and sounding board, ensuring he got through every challenge he faced smoothly. They were almost like twins, knowing each other's thoughts and intentions without a word, protecting Mondstadt in both light and dark.

...Until that fateful day, now ingrained deep in Kaeya's memory, when the convoy Diluc was escorting was attacked by a huge monster. It was the first and only time Kaeya failed in his duty. By the time Kaeya finally reached Diluc, it was all already over. The power their father had used to successfully fend off the monster also backfired and took their father's life with it.

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..."

As this dangerous thought flashed through Kaeya's mind, he simply smirked—

"This world is truly... fascinating."

Their father lay dead in a pool of his own blood. It was on that night that the two sons' paths diverged.
