Celestial Throne: King of the World

Aether, an ancient being from another world, appeared in another world with his twin sister, Lumine.

When Aether woke up, Lumine appeared before him with a panicked face, begging to leave this world, much to his confusion. Aether listened and they would have left, had it not been for a certain unknown god.

Now, Aether is trapped in the world of Teyvat and has lost most of his power.
