Genshin Impact: How To Collect The Burning Firestones (The Flowing Primal Flame Quest)

After assisting Bona in purifying the Chu'ulel Light Core from Abyssal Corruption in Genshin Impact, players must help her locate the Primal of Flame. Once found, Travelers must offer two Pyrophosphorites (obtained during the Palace of the Vision Serpent Quest) to the Altar of Primal of Flame.

This offering opens a path to Tonatiuh, a floating island above Ochkanatlan's Cradle of Fleeting Dreams fortress. Reaching Tonatiuh completes the To the Sky-Road Quest and begins The Other Side of the Sky Quest, requiring Travelers to gather four Burning Firestones to acquire the Jade of Return.
