Aether, also known as the Traveler and the Outlander, is the main protagonist and player character of the 2020 action role-playing fantasy video game Genshin Impact. Both him and his sister (Lumine) were traveling out of Teyvat, but they were blocked by an Unknown God and were both defeated and sealed away. They were separated from each other and had their powers sealed away. While the Traveler's sibling eventually returned to Teyvat, the Traveler was sealed until 500 years later.
