If you’ve just booted up Genshin Impact for the first time, you’ve probably already made your first big choice: picking between the blonde male twin and silver-haired female twin to play as. After that opening cutscene where an unknown god separates you from your sibling, you’re prompted to enter a name for your character, which might leave you wondering what's the main character's name in Genshin Impact, officially. A lot of new players get confused by the mix of customizable options, fan nicknames, and canon lore terms for the protagonist, so we’re breaking down all the key details you need to know to follow along with the story and fan discussions alike.
What's the Main Character's Name in Genshin Impact, Officially?
The official, universal name for the main character across all Genshin Impact media is The Traveler. This is the title all NPCs use to refer to your character no matter what custom name you pick, and it’s the term used in official patch notes, lore books, and promotional content from HoYoverse. The two individual twins also have set canonical given names, if you want to stick strictly to the official lore instead of using a custom name. The male twin is named Aether, and the female twin is named Lumine.
The twin you don’t pick at the start of the game becomes the Abyss Princess or Prince, the central antagonist driving most of the main story’s overarching plot. Even if you rename your playable twin, their canonical backstory as one of the two outlander twins remains the same, and the lost sibling will still be referred to by their official name in cutscenes and dialogue. I’ve seen a lot of new players pick custom names for their first playthrough, then switch to Aether or Lumine on their second account when they want a more lore-accurate experience, and that’s totally valid.
Common Nicknames for the Genshin Impact Main Character
After years of the game being available worldwide, the Genshin fan community has come up with dozens of nicknames for the main character, for everything from casual discussions to build guides. You’ll run into these nicknames all over TikTok, Reddit, and fan forums, so it’s helpful to know what they mean when you see them:
- MC/Protagonist: The most generic, widely used nickname, used by players who want to talk about the main character without referencing a specific custom name or twin choice.
- Traveler (by element): Players often add the Traveler’s current resonated element as a prefix when talking about team builds, like Anemo Traveler, Dendro Traveler, or Hydro Traveler, to specify which kit they’re discussing.
- Lumine/Aether simp: A playful, lighthearted nickname for players who main the Traveler exclusively, and rarely or never use other 5-star or 4-star characters in their team comps.
- Outlander: A less common nickname pulled directly from in-game lore, referring to the fact that the twins are not native to Teyvat, and have traveled across dozens of other worlds before arriving there.
You might also run into region-specific nicknames if you browse international fan content. In the Chinese fandom, for example, Lumine is often called Ying and Aether is called Kong, which are their original Chinese canonical names. It’s not unusual to see these names pop up in fan art or translated lore deep dives, so don’t get confused if you see them referenced alongside the English official names.
Why the Genshin Impact Main Character Has No Fixed Name for Most Players
HoYoverse intentionally made the main character’s name customizable to give players the option to self-insert into the story if they want. The Traveler is intentionally written as a mostly silent protagonist with very few fixed personality traits, so letting you pick their name makes the story feel more personal, like you’re the one exploring Teyvat and meeting all the different characters across the seven nations. That’s why you can pick literally any name you want for your Traveler, as long as it fits within the game’s character limit and content guidelines.
You might have noticed that no NPC ever says your custom name out loud, no matter what voice acting language you play with. That’s because recording thousands of possible names in four different languages would be logistically impossible and extremely expensive, so all voice lines refer to the main character as Traveler, or another generic title. I once named my Lumine “Potato” for a full month just to mess around, and it didn’t break any cutscenes or dialogue at all, since no character ever says the custom name out loud.
If you pick a name you end up hating later, you can change it once for free in your account settings. Any additional name changes cost 500 Genesis Crystals, so make sure you’re happy with your pick if you don’t want to spend real money to change it later. You can also change your Traveler’s appearance at any point, though you can’t swap between Aether and Lumine after you make your initial choice at the start of the game.
Key Lore Facts About the Genshin Impact Main Character You Might Have Missed
Even if you rename your Traveler and give them a silly backstory for your own playthrough, their canonical lore remains fixed, and there are a lot of small details most players miss even after dozens of hours of gameplay. First, the Traveler is at least 500 years old, as they arrived in Teyvat right around the time of the cataclysm that destroyed the nation of Khaenri’ah. They were asleep for 500 years after the unknown god separated them from their sibling, so they don’t remember most of what happened in Teyvat during that time.
Another little-known fact is that the Traveler’s original home world has never been named in any official lore content, though there are small hints dropped across archon quests and story chapters that they’ve traveled to dozens of other worlds before landing in Teyvat. Their ability to resonate with all seven elements is also completely unique to them, as no other character native to Teyvat can wield more than one element without a delusion, which comes with severe side effects.
A lot of players skip the Traveler’s dedicated story quests because they don’t main the character, but those quests have some of the most important lore drops about the game’s overarching plot, including clues about where the lost sibling is, what the unknown god’s motives are, and what the true purpose of the Archons is. Even if you only use the Traveler when the game forces you to, it’s worth playing through their story quests to get context for the rest of the game’s plot.
Now you know exactly what's the main character's name in Genshin Impact, whether you’re referencing their official canon titles, the fan nicknames you’ll see across social media, or the custom name you picked for your own playthrough. You don’t have to stick to one naming convention either—most players swap between Aether/Lumine, Traveler, and their custom name depending on the context. At the end of the day, the name you pick for your protagonist doesn’t change the core story or gameplay, so feel free to get as creative as you want as you explore all of Teyvat’s nations.
