Genshin Impact Version Luna I “Song of the Welkin Moon” Update Brings Nod-Krai, New Characters & Special Codes

It’s official, Travelers! Genshin Impact’s Version Luna I, Song of the Welkin Moon: Segue, arrives on September 10, 2025—and it’s shaping up to be one of the biggest updates yet. Hoyoverse has confirmed that instead of calling it 6.0, this brand-new cycle kicks off a year-long version series under the name “Luna I.” If you’ve been following the story closely, you already know what that means: a new region, a major Archon Quest, and some of the most exciting character debuts we’ve seen in a while.

Welcome to Nod-Krai – A Moonlit Land Full of Secrets

The centerpiece of Luna I is the introduction of Nod-Krai, a mysterious self-governing region at the southern edge of Snezhnaya. This place is unlike anything we’ve explored before. Charged with Kuuvahki energy—an uncommon lunar element—Nod-Krai radiates power, mystery, and a sense of looming peril.

As you step into this region, you’ll notice something different right away. Street signs hum with ancient energy, puzzles glow with unipolar fields, and everyday life here revolves around this power. Depending on the color of Kuuvahki fields, you’ll either be pushed away or drawn closer, creating clever environmental mechanics that aren’t just gimmicks—they tie directly into combat advantages and exploration.

The region is split into three distinct areas:

• Nasha Town – a lively hub where residents weave Kuuvahki into their daily routines.
• Clink-Clank Krumkake Craftshop – home of the inventive duo Aino and Ineffa, always tinkering with moon-infused gadgets.
• Hiisi Island – ruled by the Frostmoon Scions, a devout order that worships the moon goddess Kuutar and guard their traditions with an iron will.

And that’s just the beginning. As you push north, you’ll come face-to-face with the Fatui’s Kuuvahki Experimental Design Bureau, where sinister war machines fueled by this energy are under construction. Whether you go in stealthily or smash through the gates—it’s up to you, but either way, it’s a high-stakes playground.

Archon Quest: “Song of the Welkin Moon”

If you’re itching for more story, the new Archon Quest will not disappoint. This chapter pulls you straight into the heart of Nod-Krai’s conflicts—uncovering the Fatui’s schemes, ancient moon secrets, and even deeper mysteries tied to Columbina. Yes, you read that right—Columbina, the Damselette, is back, but in a completely different role. She has shed her Fatui past and now walks her homeland as the Moon Maiden.

You’ll find her at the Sanctuary of the Silver Moon Court, a serene yet powerful stronghold that offers more than just lore—it’s a chance to earn her assistance on your journey. The game even teases a link between her appearance and the statues of the Idol of the New Moon scattered across the land. That’s the kind of lore breadcrumb Genshin fans like me live for!

The Archon Quest also has you teaming up with new allies like Lauma, the Moonchanter of the Frostmoon Scions, and Flins, a veteran Lightkeeper. Both characters embody the struggle between tradition, faith, and the raw pull of Kuuvahki energy. Your decisions and battles alongside them will literally shape the fate of this moonlit region.

Meet the New Characters: Lauma, Flins & Aino

Let’s be honest, most of us are counting primogems already. So, here’s the breakdown of what’s coming:

• Lauma (5-star Dendro Catalyst)
  • Specializes in a brand-new mechanic called Lunar-Bloom, which converts the regular Bloom reaction into a powerful damage-dealing version.
  • Collects Verdant Dew to unleash devastating AoE Dendro attacks.
  • Capable of reducing enemy Hydro and Dendro resistance—making it a game-changer for team synergy.
  • Outside of combat, she can transform into a cervitaur form to sprint across the land.
• Flins (5-star Electro Polearm)
  • A Lightkeeper with an aristocratic vibe and a combat kit built around Lunar-Charged DMG.
  • Can switch between burst-heavy or tempo-based combat depending on the fight.
  • His dual-style kit means you’ll need to adapt mid-battle—something veteran players will love.
• Aino (4-star Hydro Claymore)
  • The “Whiz-Kid Mechanic” from Nod-Krai.
  • Free character via the Archon Quest (yes, free!), making her instantly valuable.
  • Brings Hydro utility to the team, plus loads of personality from her day-to-day tinkering.

What I really love here is that each character isn’t just combat fodder. Through the new Meeting Points system, you’ll actually interact with them in their own spaces—whether that’s helping Lauma at the Frostmoon Enclave, hanging out with Aino in her workshop, or listening to Flins share Lightkeeper legends at his home. It’s a level of immersion that makes the world feel alive, and honestly, it feels like Hoyoverse is leaning harder into RPG territory with this feature.

Limited-Time Events & Rewards

Of course, no Genshin update is complete without events. The headliner this time is Clink Clank Clash, a quirky, combat-driven event where you’ll earn an exclusive event weapon. Pair that with seasonal challenges, world exploration puzzles, and the always-expected primogem rewards, and you’re looking at a packed calendar.

But the cherry on top? This update coincides with Genshin Impact’s 5th Anniversary. Hoyoverse is celebrating by handing out:

• 10 Intertwined Fates
• 1,600 Primogems
• Two exclusive gadgets
• And—this one’s huge—a free 5-star standard banner character of your choice

That’s not just fan service—that’s Hoyoverse saying “we know you’ve stuck with us for five years, and here’s something truly rewarding.”

Banners & Event Wishes – Who to Pull For?

Banner watchers, here’s the lineup you’ve been waiting for.

• In the first half of Version Luna I, you’ll get the debut of Lauma alongside a Nahida rerun. If you missed the Dendro Archon the first time around, this is your chance to fix that. Plus, Lauma’s kit screams synergy with Hydro characters—she’s basically made to supercharge Bloom teams with her Lunar-Bloom reaction.
• In the second half, the spotlight shifts to Flins, Yelan, and of course Aino. What’s particularly interesting here is that Aino, though obtainable for free via the Archon Quest, will also be featured in the wish banners—so you can grab constellations to power her up even further.

If you’re wondering where to spend your primos, here’s my take: Lauma looks like a game-changer for anyone invested in Dendro comps, while Flins brings a flexible playstyle that veterans will appreciate. If you’re low on primogems, remember—you also have those anniversary rewards coming to help you snag at least one 5-star this patch.

Now, let’s talk free stuff. The special program livestream dropped three limited-time codes that every Traveler should redeem right now:

• HiFiveTraveler

Each of these codes gives you a bundle of Primogems, Mora, and Adventurer’s EXP. But here’s the catch—they expire on Sept. 1 at 12 a.m. EDT. That’s incredibly soon, so don’t procrastinate.

👉 Quick guide to redeeming:

2. Browser method: Visit the official redemption site, log in, and copy-paste the codes (easier and faster).
3. Rewards will arrive almost instantly via in-game mail.

I can’t stress this enough: log in and redeem them before you forget. Primogems are currency you never want to leave on the table.

Developer’s Words on Luna I

Here’s where things get exciting on a meta level. Zhenzhong Yi, Studio Technical Director at HoYoverse, shared an official statement about the Luna I series:

“Greetings, Travelers! We’re excited to announce that Genshin Impact Version Luna I, Song of the Welkin Moon: Segue, will be released on September 10. This update, which marks the beginning of the year-long Song of the Welkin Moon version series, will also introduce a major new region, Nod-Krai.”

What this tells me is clear: Hoyoverse isn’t treating Luna I as just another patch. This is a reset point, much like Inazuma’s arrival back in 2.0. It’s the start of a new era of storytelling, with plotlines designed to tie together lingering mysteries about Teyvat, the Fatui, and the moon’s secrets.

Why Luna I Feels So Important for Genshin’s Story

The moon has been a recurring symbol in Genshin lore, and now we’re finally seeing it take center stage. Nod-Krai isn’t just another scenic map—it’s a region woven directly into the Traveler’s overarching journey.

• The Lightkeepers vs. The Wild Hunt brings an aura of legendary menace that overshadows ordinary regional struggles.
• Columbina’s shift into the Moon Maiden might mark the start of a redemption journey—or perhaps foreshadow an even darker twist within the Fatui ranks.
• The introduction of Kuuvahki energy and its role in combat, exploration, and story feels like a foundation for future mechanics, not just a one-off gimmick.

From what I’ve seen, this is the most lore-heavy update since Inazuma—and if you’re someone who plays Genshin for the story, Luna I looks like the payoff to years of world-building.

Between a brand-new region, three playable characters, lore-packed Archon Quests, anniversary freebies, and limited-time codes, this update is basically a love letter to Genshin’s global community.

If you’ve been waiting for a reason to dive back into Teyvat—or you’re a veteran hoarding Primogems for the “right” character—this is your moment. Personally, I’m excited to wander through Nod-Krai beneath the moonlight, uncover its hidden mysteries, and discover how Lauma, Flins, and Aino reshape the gameplay experience.
