Lumither

"We will meet at this journey's end... Once the dust has settled."

- Lumine to Aether

Lumither is the family ship and het ship between Aether and Lumine from the Genshin Impact fandom.

Canon
At the beginning of the game, Aether and Lumine were separated by an unknown god. They've had little canon interaction since.

In the Prologue of the game "The Outlander Who Caught the Wind", The Knights of Favionus asked Aether/Lumine what reward they wanted for defeating Dvalin and saving Mondstadt, to which Aether/Lumine replied that they wanted Missing Person Posters put up around Mondstadt to look for their lost kin.

Later, Chapter I of the game "Farewell, Archaic Lord", Aether/Lumine repeated this sentiment, asking that Missing Person Posters be put up around Liyue Harbor. During the Lantern Rite Festival Event, Aether/Lumine made a wish for their respective sibling, stating "That's my sister's deepest desire." or "I really hope her wish will come true" if you picked Aether as the MC. If you picked Lumine as the MC, she'd say "That's my brother's deepest desire." or "I really hope his wish will come true".

In a world quest that is treated like an Archon Quest "Bough Keeper: Dainsleif" Quest, Aether/Lumine then met Dainsleif, after fighting the enemies, Aether/Lumine sensed something familiar at a cliff, they then went to the cliff and examined the Dandelion, there was a rewind that was from the beginning of the game, if you picked Aether as the MC, he then says "This dandelion...reminds me of..." or "I...could feel her." and if you then picked Lumine as the MC, she then says "This dandelion...reminds me of..." or "I...could feel him.", after that Aether/Lumine then had to get to the bottom of this but Dainsleif stopped Aether/Lumine, Dainsleif was also now leaving.

Fanon
This ship isn't very popular as a het ship, due to the fact they have very little canon interaction. It has been widely disliked due to it's incestuous nature. There are few fan arts or comics/manga of a lover's relationship between them, but the ship was made more popularized through family-ship style media.
