Traveler/Lore

==Personality==
The Traveler's personality is determined primarily by the player themselves through dialogue options.
Their personality can range from stoic, humble and helpful to boastful, lazy, and short-tempered. Regardless of the player's in-game decisions, they are generally liked by the playable characters. There are instances of single speech options or similar options which give a glimpse at their personality overall. They are, for example, observed by Paimon as not believing the gods are any more worthy of unearned respect than mortal inhabitants of Teyvat. They also are pointedly uninterested in getting involved with each nation's troubles and primarily only concern themselves with finding out their sibling's whereabouts. Their response to Morax's "death" was initially to simply leave, both to avoid suspicion and seemingly a level of apathy considering the circumstances of their arrival on the world. 
This trend continues into Inazuma, where the Traveler initially denies aid to the rebellion and refuses to take sides, interested only in meeting with the Raiden Shogun. The Traveler is visibly frustrated, not wanting to meddle in the country's affairs or get involved with anyone, even for a task as simple as delivering a letter. Yet despite this hesitation to get involved, they are ultimately a compassionate person, eventually choosing to aid the resistance against the Shogun's injustice after seeing the circumstances of each situation particularly at the prodding of Kamisato Ayaka and Thoma. Later on in Sumeru, they later help free Lesser Lord Kusanali from the sages of the Sumeru Akademiya after learning of her plight. Despite their slight indifference to Teyvat's conflicts, they greatly cherish every bond they create with the people. Arlecchino also believes that the Traveler is incapable of performing intentionally malevolent acts.
The Traveler does not appear to be very talkative, with several characters noting that they are not very fond of speaking or starting conversations. Though Shikanoin Heizou once joked about Paimon serving as the Traveler's "voice," the Traveler does indeed prefer having Paimon speak on their behalf.
Due to their experiences with the Fatui and the Abyss Order, the Traveler is immediately on guard at the mere mention of them. The Traveler is shown to be friendly to a degree to those that respect them, such as Tartaglia and Enjou. Although initially friendly with Lyney and Lynette, their friendship was damaged after they failed to inform the Traveler that they were Fatui operatives from the House of the Hearth (as they knew of their interactions with them). Eventually, after some apologizing from Lyney, the Traveler reconciles with them, and subsequently maintains a good relationship with Arlecchino and the House.
They also show significant concern for their sibling, as their initial goal was to find them and get answers from the Unknown God that sealed them away. Upon reuniting with their sibling, the Traveler was more concerned with returning home with their sibling as opposed to their role as the Abyss Order's leader or their war with the Heavenly Principles. Despite their position with the Abyss, they still miss them dearly, and continue to follow their instructions in seeing the world for themselves.
==Appearance==
Aether uses the medium male model, and Lumine uses the medium female model. Both siblings have hair, fiery-gold eyes, and pale skin. During their fight with the unknown god, both siblings had yellow wings.
Aether's hair is a more saturated color and very long, while Lumine's hair is paler and chin-length except for two locks of shoulder-length hair framing her face. Lumine also has two light-blue Inteyvat flowers pinned on the right of her head and two pale blue feathers tucked at the left.

==Trivia==
* No default name is given for the Traveler at the start of the game. Their real name, Aether (male) or Lumine (female), was first determined through the name the Traveler calls their sibling by in the opening cutscene. Later, during We Will Be Reunited, their sibling calls the Traveler by their real name regardless of the name the player chose. Within Caribert's memory it's revealed that they're the only ones to use these names for each other.
* Aether and Lumine are seen wielding a multitude of weapons across in-game cutscenes and official media:
** In the opening cutscene during the with the Unknown God, they are shown wielding white-and-gold swords. Aether's sword had a cruciform guard and Lumine's sword had a crescent guard.
** They are shown wielding the ascended version of the Silver Sword in their character cards and portraits.
** They are shown wielding the Dull Blade in most in-game cutscenes.
** They are shown wielding Prototype Rancour in the cutscenes during , , and .
* The Traveler is currently the only playable character who:
** Does not have a Utility Passive.
** Has their Vision listed as "None" on their profile.
** Has no Friendship Level listed in Attributes, and Story passages are instead unlocked by completing certain Archon Quests.
** Does not appear in the Character Archive at all, and thus cannot have their full "Wish" artwork viewed there like those of all other characters and outfits.
*** Their "Wish" artwork does show up in the credits of the Imaginarium Theater, though not in full.
** Uses different means from other characters to obtain materials used for Ascension and Constellations.
*** Ascensions require the Brilliant Diamond Character Level-Up Material, which are only obtainable through Adventure Rank rewards.
*** Ascensions do not require Ascension Gems.
*** Constellations, which are maintained separately for each element, require Memories, which are obtained through various means, including Adventure Rank rewards, Quest Rewards, and the Souvenir Shop or similar of the respective city, as opposed to Stella Fortuna obtained for other characters from wishing. As a result, neither the male nor female Traveler have Wish artworks.
**** The Traveler was initially the only playable character who was completely unavailable through wishing. As of Version 2.1, Aloy is also unavailable through wishing. However, unlike the Traveler, Aloy shows up in the Character Archive and has her "Wish" artwork viewable there.
* Though the Traveler does not possess a Vision, they are still able to use the power of the seven elements by resonating with Statues of The Seven, and do not require the respective Archon's permission to do so. For gameplay purposes, the player must use a Statue of The Seven of the corresponding nation each time they wish to switch the Traveler to a different element.
** The Traveler's clothing will glow with the color of the element they are resonating with: teal for , yellow for , purple for , green for , blue for , and orange for . When unaffiliated with an element, those parts won't glow. In the opening cutscene with the Unknown God, both siblings' clothing will glow white. The Traveler's Sibling's clothing glows white in their present-day appearances, but the Traveler's will match their resonated element.
*** In lore, the Traveler can access any previous element they've resonated with at will. During the mid-battle cutscene in , the Traveler uses both Anemo and Geo, regardless of their currently resonated element. This ability to wield multiple elements at once is shown again in , as the Traveler demonstrates to Kachina their use of Electro, Hydro, and Anemo in front of a Statue of The Seven. During those quick-swaps, the Traveler's gems immediately switch to the relevant element's glow.
*** Starting in Version 2.0, pre-rendered cutscenes and Hangout Memories usually have the Traveler's element match the region's element instead of the player's current Traveler alignment.
** Pyro is the only element the Traveler was unable to resonate with upon first arriving in Natlan. For this reason, art and cutscenes featuring the Traveler in Natlan kept the blue Hydro elemental glow, obtained in the previous region of Fontaine, until , where Yohualtehcutin grants the Traveler the element along with special Constellations to aid in defeating the Lord of Eroded Primal Fire. Afterwards, the Traveler can resonate with Pyro with Natlan's Statue of the Seven just like other elements. 
* The Traveler is one of the characters with ornaments that glow. 
* 
* In the Traveler's Chinese official introduction, as well as the first official artbook, their profile's Constellation parameter reads , which is not found on any other character's profile.Chinese HoYoverse: In-game, the Traveler's Constellation parameter is named the same as everyone else's.
* Despite their youthful appearance, the Traveler descended on Teyvat five hundred years ago and has been traveling between different worlds for an unknown amount of time before that, making them older than they look. In a developer video regarding Azhdaha's design, one developer mentions that "the Traveler's life span is by no means short."Design Notes, Azhdaha: The Birth of a Dragon § Core: Azhdaha's Initial Design A running gag in the game features the Traveler hoping to drink alcohol only to be rebuffed, probably on account of their youthful appearance. On other occasions, the Traveler voluntarily rejects alcohol. Voiceover lines with Paimon indicate, however, that the Traveler thinks and acts in a manner befitting a mature adult.
** As such, a select few characters are aware the Traveler comes from outside Teyvat:
*** Barbatos, Morax, Beelzebul, Buer, and Haborym are aware of the Traveler's origins, likely due to their status as part of The Seven, though Barbatos had to be explicitly informed by Paimon of this as he was initially unaware. The Tsaritsa is also likely aware of this, as Buer was able to locate Fatui records categorising the Traveler as one of the Descenders.
**** Although she was maintaining a façade of being an Archon, Furina is aware of the Traveler's origins, as the Traveler told her about it during their discussion prior to her trial.
***Neuvillette is aware of the Traveler's origins, likely due to being one of the Seven Sovereigns and their shared experiences of being outsiders to Fontaine.
*** Fischl and Kamisato Ayato are somehow able to determine this without any apparent logic.
*** Mona determines this through her astrology.
*** Albedo compares himself similarly to the Traveler, while also discerning this through their ability to use multiple elements without a Vision.
*** Similarly to Albedo, Kaedehara Kazuha also notes that the Traveler is capable of using multiple elements without a Vision, while also commenting to them that they have an "incredibly complex" smell that he compares to a mysterious being.
*** Xinyan also knows that the Traveler is not from this world. Based on how she talks about this fact, it seems that the Traveler has deliberately told her about their origin.
*** Ganyu has at least been able to clue in that the Traveler is different from other people of Teyvat, viewing them as something not exactly human similar to herself.
*** Aloy was told by the Traveler that they also aren't from this world, and that they stayed to look for their sibling.
*** The Traveler reveals this to Nilou, Navia, Kirara, and the Wanderer at the end of Summertide Scales and Tales by saying they have "traversed many worlds" in their blessing to Mini Durin.
*** Through fortune-telling, Citlali determines this and the Traveler's status as a Descender. Xilonen is also present at the event.
*** When Lan Yan attempted to connect the Traveler to the Seven-and-Eight Gate Method array, the Ley Lines did not respond due to them not containing information on the Traveler, a revelation that surprised Lan Yan. Ningguang was present when this occurred.
* The Chinese version of the opening cutscene trailer is titled , which incorporates both Aether and Lumine's default names.Bilibili: 
* According to the Chinese, Japanese, and Korean pronouns the twins use to address each other in the opening cutscene and in later interactions, Aether is the older twin and Lumine is the younger. The English translation does not make distinction on which is the older/younger twin.
* The Traveler is implied to be skilled at playing chess, or at least good enough to surprise Diluc.
* As children, both the Traveler and their sibling had imaginary friends.
* The Steambird's Teyvat Food Notes columnist, Long'er, is a rendition of Aether. (See Teyvat Food Notes § Trivia for details.)
* The Traveler likes rock 'n' roll.
* The reveals that the Traveler is proficient in archery. However, because the Traveler only wields a sword in-game, they must rely on ranged Talents such as Starfell Sword to complete the commission.
* The Traveler's voice-over line About Jugemu references the famous about a child named a very long name due to his parents' indecision.
* The Traveler's voice-over line About Tanuki has the traveller humming "Shojo Temple Tanuki" in Chinese, Japanese, and Korean. In English, the traveller hums randomly.
* The Traveler and the Captain from are both seen commenting on a video in the Character Trailer for Robin from , both of which are HoYoverse games.
** The Traveler's profile picture is shown to be a silhouette of Aether's in-game avatar. Likewise, the Captain's is shown to be a silhouette of Ai-chan.

* The Traveler is the first Ancient Name bearer to not be a native inhabitant of Natlan.
* The Traveler is referred to by several nicknames:
** Their blonde hair has been the basis of a few nicknames, such as Kayabuki Ikkei's "blond-haired outlander" and "Golden Whirlwind," Taliesin's "golden-haired ," and Kichiboushi's "Yellow Fur" (shortened from " Yellow Fur"). In Sumeru, the Aranara give the Traveler the nickname "Golden Nara" presumably also in reference to their blonde hair.
*** The Traveler is not fond of such nicknames, going as far as to call Taliesin's (and Paimon's "Blondie") "terrible-sounding, non-consensual appellations." They also disapproved of Kichiboushi's nickname, but tolerated it for the duration of Eight Locales Over Mountains and Seas.
** Teucer addresses them as " throughout , because despite having known the Traveler's identity the entire time, he forgot their name.
** The Traveler and Paimon are sometimes called "the Guests of Tenshukaku" by Inazuman characters, such as Souka in the Fabulous Fungus Frenzy event.
** Souka also referred to the Traveler as "Her Excellency's Hanamizaka tour confidante."
** A prince/princess in exile (by Liloupar)
** Knight (by Ann and other members of the Narzissenkreuz Adventure Team)
