How old are Lumine and Aether in Genshin Impact?

Genshin Impact is a lore-heavy game, and the main story revolves around two twins who were separated. While many things in Genshin Impact are still being revealed, there are a few story details that the developers have confirmed. Some of these have to do with the mysterious lead character(s) Lumine and Aether.

Lumine and Aether are referred to as twins, meaning that they are the same age. Their appearance seems to be around 14 to 16 years old, but we know that they have been in Teyvat for more than 500 years. This is confirmed by the fact that they were separated after trying to flee the world during the fall of Khaenri'ah.

We also know that they have likely traveled to many worlds before, possibly making them much older than originally thought. It can be assumed that the two are likely immortal or long-lived as neither of them has aged during their time in Teyvat. Even during your travels with Paimon, the twin you choose shows no signs of growing any older.
