After taking the commission that Ganyu and Lan gave to Aether, he was devastated to see what happened during that time. He saw his sister Lumine, but he felt confused, sad, and angry. He could have taken her with him, show her around Mondstadt and Liyue, meet his friends and eventually stay there with him. But then, it was not possible, for she was the Abyss Princess. Dainsleif had gone after her and Aether did not fully grasp what happened, from Khaenri'ah's and Dain's true nature to Lumine's so-called 'war with destiny'. The events that occurred that day were too much, and he still thinks about it. What did Lumine really mean that day? What did she mean by the "true nature" of the world? Aether remembered that her sister had already traveled through Teyvat and could only wonder what was waiting for him at the end of his journey.
