Lumine

Lumine is the lost twin sibling of the Traveler and the princess of the Abyss Order. The primary goal for the Traveler in Genshin Impact is to find and reunite with their sibling — traveling through Teyvat, obtaining information about them from meeting with The Seven. The physical appearance of the sibling is very similar to the Traveler's. Both have slim figures, (blond/blonde) hair, golden-yellow eyes, and very pale skin. Lumine's hair is a bob cut with shoulder-length, straight twin-tails; while Aether's is medium cut with a long braid. Lumine wears a pale white sleeveless dress with blue lines and tail capes, with gloves covering her thumbs. Also, she wears white stockings and boots; Aether wears a dark breastplate vest and black boots, with dark brown pants, a white scarf and a two-tailed cape with golden embroidery and decals. Certain parts of the Traveler's clothing light up based on the current element they are attuned to. In the opening cutscene, both siblings are seen with glowing white clothing and yellow wings. However, though they retain their glowing white clothes, the sibling has yet to show use of any of the Seven Elements in or out of combat. In the Archon Quest Chapter I: Act IV - We Will Be Reunited, the Sibling is shown wielding the same white-gold sword as in the opening cutscene, but it now glows with dark energy. Lumine has a vendetta against the divine after finishing their journey across Teyvat for reasons unknown. She is solely devoted to accomplishing the goals of the Abyss Order regardless of what has to be done to do so. Despite her questionable actions, the sibling still cares for the Traveler, as she expresses a desire to return home with him after finishing her goals and convinces him to continue his journey across Teyvat to witness the truth himself rather than forcing her views on him.
