Fragment of Childhood Dreams in Genshin Impact is a permanent Sumeru search problem with a specific unlock or completion route. Fragment of Childhood Dreams is a one-time Sumeru domain hidden behind a two-stage water-draining route. The useful preparation is a Dendro character plus a Bow user, because the cave uses Dendro Monuments, Dendrograna targets and a final mechanism.
For Fragment of Childhood Dreams, the important part is separating the visible destination from the progression flag behind it. In Sumeru, reaching Fragment of Childhood Dreams physically does not always mean the quest, mechanism or reward is ready, so the order below avoids unnecessary backtracking.

Fragment of Childhood Dreams in Genshin Impact becomes much easier once the required progression is in place. Check these conditions before committing to the route, especially if your map already shows Fragment of Childhood Dreams but the interaction itself is not working.
- Reach Adventure Rank 35.
- Complete The World of Aranara so the relevant Sumeru exploration route is available.
- Bring Dendro application and a Bow character before entering the cave.
Step-by-step route
- Start near the Statue in the Fane of Ashvattha area and activate the first mechanism to lower the water.
- Enter the cave behind that mechanism and move into the central chamber.
- Find and activate all four Dendro Monuments, including the ones hidden behind the green barrier and breakable rocks.
- Use the newly available mechanism to lower the water again.
- Continue deeper, summon Dendrograna and shoot the sequential Dendro targets at the domain entrance.
During Fragment of Childhood Dreams in Genshin Impact, keep the relevant quest or map layer visible instead of navigating only by the surface marker. Around Fragment of Childhood Dreams, Sumeru uses underground routes and progression-gated interactions heavily, and the intended path often becomes obvious only after the previous step has registered.
A hidden Dendrograna source is used to reveal some of the monuments that are not immediately visible.
The second target at the final doorway appears only after the first Dendro target is hit correctly.
Why it can still look locked or incomplete
The most common mistake is stopping after the first water drop. The domain still remains submerged until the four Dendro Monuments unlock the second drain mechanism.
If Fragment of Childhood Dreams in Genshin Impact seems stuck, compare your current objective with the prerequisite list before assuming the game has bugged. The most common failure point around Fragment of Childhood Dreams is reaching the correct location one quest step too early or solving only part of a multi-stage mechanism.
Useful details before you leave the area

Common questions
Why is Fragment of Childhood Dreams not working for me?
For Fragment of Childhood Dreams in Genshin Impact, the usual causes are incomplete prerequisite progression, approaching from the wrong map layer, or missing one local interaction. Work backward from the current Fragment of Childhood Dreams quest text rather than redoing unrelated exploration elsewhere in Sumeru.
Is Fragment of Childhood Dreams permanent?
Yes. Fragment of Childhood Dreams is part of permanent Sumeru content rather than a limited-time event. Later game updates can adjust interface details around Fragment of Childhood Dreams, but its underlying quest or exploration route remains available to accounts that have not completed it yet.
What should I do next?
After opening the domain, activate it immediately so it becomes a permanent teleport point even if you leave the cave before completing every nearby exploration objective.
After Fragment of Childhood Dreams in Genshin Impact, the next useful move is to finish the nearby follow-up content while the route is fresh. HoYoverse keeps current game notices on the official Genshin Impact website if a later update changes any interface or progression detail around Fragment of Childhood Dreams.
