After assisting Bona in purging the Abyssal Corruption from the Chu'ulel Light Core in Genshin Impact, players are tasked with locating the Primal of Flame. Once found, offering two Pyrophosphorites—collected during the Palace of the Vision Serpent Quest—to the Altar of Primal of Flame is essential. This act paves the way for players to ascend to Tonatiuh, which hovers above the Cradle of Fleeting Dreams fortress in Ochkanatlan. Upon reaching this floating island, the To the Sky-Road Quest concludes, ushering in The Other Side of the Sky Quest. At this point, players must gather four Burning Firestones to secure the Jade of Return.

Subsequently, the Dragon of the City of Flowing Ash will interrupt the journey once more. Players must then follow the Taunted One to the Nursery of Nightmares island to finish The Other Side of the Sky Quest in Genshin Impact, earning 50 Primogems in the process.
