Hey, fellow Traveler! If you’ve just helped Bona cleanse the Abyssal Corruption around the Chu’ulel Light Core, your quest log probably looks like a riddle wrapped in a Pyro puzzle. I know mine did. The next step sends you after the Primal of Flame, then up to Tonatiuh, the dreamlike island floating above Ochkanatlan’s Cradle of Fleeting Dreams. To finish The Flowing Primal Flame and unlock The Other Side of the Sky, you need four Burning Firestones. In 2026, this chain still feels like one of Natlan’s most cinematic detours, so here’s my first-person walkthrough for collecting every stone without losing your mind—or your map.
First, a quick reality check: after locating the Primal of Flame, you must present two Pyrophosphorites at the Altar of Primal of Flame. You should have collected them during the Palace of the Vision Serpent Quest. That offering creates the path to Tonatiuh and completes To the Sky-Road Quest. If you skipped that part, the game will politely—yet firmly—remind you.
This quest chain is less a checklist and more a séance conducted by a cartographer who keeps redrawing the map mid-ritual. So take a breath. We’ll go stone by stone.
🔥 Burning Firestone #1: The Welcome Wagon
From the ethereal heights of Tonatiuh, the first Burning Firestone is practically handed to you—after a cutscene, naturally.
-
Make sure you’ve reached Tonatiuh.
-
Watch Bona’s captivating cutscene. The Little One gathers the first Burning Firestone.
-
Trail the Little One toward the bridge.
-
Activate the mechanism next to the bridge to raise the lift.
-
Interact with the cheerful Saurian and talk to Bona.
-
Brace yourself for another cutscene.
That’s it. One down. If you’re like me, you’ll spend the next five minutes staring at the floating architecture and wondering who pays the maintenance bills.
🔥 Burning Firestone #2: Northeastern Isle
The second stone waits on the northeastern isle. Here’s the route I used:
-
Rotate both the right and left floating isle mechanisms.
-
Cross eastward over the extended bridge.
-
Raise the lift to access the next area.
-
Follow the Little One until it points you to the second Burning Firestone.
-
Keep an eye out for a Common chest along the way.
-
Activate the mechanism to the right of the Firestone location.
-
Ascend the newly spawned platforms to the upper floor.
-
Defeat the enemies waiting there.
-
Claim the Exquisite chest atop the tower.
-
Engage the mechanism behind the chest to unveil the gate.
-
Return to the Saurian, open the locked door, and choose: 'Let’s return to the altar!'
-
Navigate back to the Altar of Primal of Flame.
Tonatiuh’s floating islands rearrange themselves like a librarian reshelving books while the floor tilts. Don’t fight it. Just follow the Little One and trust the lifts.
🔥 Burning Firestone #3: The Secret Source Sentinel Shuffle
The third stone involves a little more spectacle. The Secret Source Sentinel’s route is a silent ballet performed by a clock that refuses to tick in order—beautiful, confusing, and slightly rude.
-
Rotate the right floating isle mechanism, then the northern one.
-
Cross the bridge toward the northern isle’s lower level.
-
Shadow the Little One and watch the Secret Source Sentinel transport the third Burning Stone to the southwestern isle.
-
Head toward the northwestern edge.
-
Transform into a Qucusaurus and soar toward the Pyroculus.
-
Activate the mechanism inside the tower.
-
Fly up to the previously locked door and engage the lift to return to the upper floor.
-
Join the Little One, activating the lift on the way back to the Altar.
If you miss the Sentinel’s movement, don’t panic. The quest markers are generous, and the Qucusaurus transformation makes the vertical detour feel like a victory lap.
🔥 Burning Firestone #4: Northwestern Isle Upper Level
The fourth and final Burning Firestone sits at the northwestern isle’s upper level. This one has combat, so bring a team that can handle a sudden skirmish.
-
Walk briskly across the northwestern bridge.
-
Call upon Bona to adjust the bridge upward.
-
Jump and glide to the northern isle’s upper level.
-
Lower the lift and follow the Little One carefully.
-
Round up the spawned enemies with a strong team.
-
Ask the Saurian for help returning to the altar.
-
Collect the Precious chest along the way.
-
Conclude your journey at the Altar of Primal of Flame.
After this, you can finally offer all four Burning Firestones at the Altar. That completes The Flowing Primal Flame Quest.
🎁 The Payoff: Golden Entreaty, Dragon, and 50 Primogems
Once you offer the stones, enjoy a riveting cutscene where flames morph the Jade of Return into a Golden Entreaty. That’s a significant turning point, and it’s one of those moments where Genshin reminds you that lore and loot can share the same campfire.
But your journey doesn’t stop there. The Dragon of the City of Flowing Ash appears and disrupts your path again. Follow the enigmatic Taunted One to the Nursery of Nightmares island to finalize The Other Side of the Sky Quest. Your reward: 50 Primogems. 💎
Here’s a quick reference table for the four stones:
| Firestone | Location | Key mechanic |
|---|---|---|
| #1 | Tonatiuh arrival | Bona cutscene, bridge lift |
| #2 | Northeastern isle | Rotate mechanisms, cross bridge, tower chest |
| #3 | Northern / southwestern isle | Sentinel tracking, Qucusaurus flight |
| #4 | Northwestern isle upper level | Bridge adjustment, combat, Precious chest |
💡 My 2026 Tips for a Smooth Run
-
Bring a flexible team. You never know when a cutscene will end and a fight will begin.
-
Use the Qucusaurus transformation whenever the quest offers it. It turns frustrating vertical puzzles into short flights.
-
Check every side path for Common, Exquisite, and Precious chests. They add up.
-
Don’t rush the Little One. It’s basically a glowing tour guide with four legs and zero patience for your detours.
-
If you’re returning to this quest in 2026, the steps remain the same, but your roster is probably stronger. Enjoy the spectacle.
As you traverse Teyvat, the quest for the Burning Firestones does more than raise your character’s abilities. It reveals the intertwined destinies of Natlan’s people, its dragons, and its land. Each stone is a flicker of history, and together they ignite a story that’s worth the climb. May your adventures in this magical realm be filled with wonder, discovery, and at least one perfectly timed Qucusaurus glide. 🌋✨
