Community members are curious about how old the knight captain Kaeya is in Geshin Impact.

Kaeya is a tall, lean young man with dark skin, according to his description. He has purple eyes with long eyelashes, diamond-shaped pupils, and long, dark cobalt hair with highlights that is usually pulled back into a low ponytail. Most of his armor is navy with the exception of a black eyepatch and white fur cloak. Currently, he is Cavalry Captain of the Knights of Favonius.

How Old is Kaeya in Genshin Impact

Kaeya is at least 25 years old, according to assumptions based on the game's lore.

In-game, players are made aware that Kaeya has been a member of the Knights of Favonius for about a decade. Since he certainly doesn't look like the typical 10-year-old — and it's dubious that the knights would accept an infant into their ranks, let alone allow him to use a weapon — he must be older. The question is by how much.

Unfortunately, players aren't privy to much surrounding Kaeya's birth. His birthdate is Nov. 30 — making him a Sagittarius — but there is no year listed. We'll need to search elsewhere for that information.

According to the lore, the youngest warrior to join the ranks of the Knights of Favonius was 15 at the time of their induction. It's never said that this is or isn't Kaeya. However, assuming that this could be him and adding on the length of experience he's been with the group, Kaeya would have to be 25 at the youngest.
