Chilaether

Chilaether is the slash ship between Tartaglia and Aether from the Genshin Impact fandom.

Archon Quest
Aether first meets Childe in 'Archon Quest Chapter 1 Act 1'. Aether is escaping to avoid suspicion of being the culprit of Rex Lapis' murder. When he was at the stairs he stepped on shard of glass accidentally grabbing the guards attention. Unfortunately, he gets surrounded by the guards until he hears Childe's voice saying "Hey buddy-- Hold still,". Childe then knocks all the guards unconscious and escapes with Aether. After both Paimon and Aether are exhausted from running, Childe formally introduces himself. Of course, that wasn't his real name but an alias of sorts. Paimon and Aether figured that Childe is one of the Fatui. Childe claims he isn't here for trouble, but is here to help them. Childe trusts Aether for not killing Rex Lapis since he's been keeping an eye on Aether. Childe has gave Aether a fake Sigil of Permission created by the Fatui, and the story continues.

Aether enters The Golden house to check on Rex Lapis' Gnosis, there he sees Childe who also had his eyes on Rex Lapis' Gnosis. Childe then challenges Aether to a battle. Aether successfully defeats Childe three times throughout three stages, but Childe wasn't finished. With all the Sigil of Permissions that the Fatui have been reproducing Childe summons Osial, Overlord of the Vortex.

Monoceros Caeli
In Tartaglia's Story Quest which can be unlocked at Adventure Rank 40 with Story Key, is where Aether and Paimon meet Teucer or Childe's Little brother, almost at the end of the Story Quest Aether, Paimon and Teucer are at Northland Bank and, Paimon said that Teucer has been following them/Aether and Paimon the whole time, Teucer then gave an answer saying that he knew Aether and Paimon the whole time because of a letter that Childe sent home. Teucer also said, that if Childe could quit his job, then he would join Aether on adventures and after Teucer then left, Childe then appeared and he explained to Aether and Paimon that he didn't want his brother to see him all weak as his last memory of him. Childe invites Aether and Paimon to Snezhnaya they agree after all they made a pinkie promise to Teucer.

Fanon
This ship is still popular although Chilumi takes the popularity since it is also one of the 3rd most written fanfictions in AO3. Mostly, slash ships in the fandom are more popular than het or femslash but for Chilumi, it has beaten Chilaether.

Chilather tends to be controversial depending on fans as Aether has no official age so a few fans decrypt Aether as a minor while the other thinks Aether is an adult. After the release of the new archon it's revealed Aether is five hundred years old, it still caused some controversy as those who oppose the ship earlier on believe despite the number of his age, as those believed Aether 'still' has a body of a minor making him still a minor. However those theories were debunked in Diona's hangout as Aether mentions just because he looks young doesn't give the fact he's actually way older than he is, debunking the fact Aether is underage.

The ship became also popular because of the Childe Story Quest, in which Aether is befriending Childe and is promising Childe to visit him and his Family in Snezhnaya.

In AO3, Chilaether has 200+ fanfictions. It's less than the ship with his sister, Chilumi, but it's still a lot.
