The Fountain Flows Again is a Genshin Impact Hidden World Quest that can be accepted in Fontaine. I recommend completing it as it's part of the nation's Reputation Board. However, you can't accept the quest through a blue exclamation mark on the World Map. If you're having trouble finding it, here's how.
Where to find The Fountain Flows Again Fontaine World Quest in Genshin Impact
To unlock The Fountain Flows Again World Quest, you must first complete the following prerequisites:
- Archon Quest Chapter IV: Act I - Prelude of Blancheur and Noirceur
- Archon Quest Chapter IV: Act II - As Light Rain Falls Without Reason
When you're done, head to the midway point between Marcotte Station and the Fountain of Lucine, where you'll find a pool of water with a malfunctioning fountain. Its exact location is circled in the image below.
To trigger the World Quest, inspect the fountain by interacting with it. An NPC named Remaudiere will appear. He'll ask you to speak with Edel. Keep going forward, toward the direction of the Fountain of Lucine, to find and speak with Edel.
Next, head to the Beaumont Workshop in the Court of Fontaine, marked by the blacksmith icon in the World Map. Speak to the blacksmith, Estelle, and give her three Iron Chunks. Once you're done, you'll be teleported back to the broken fountain, triggering dialogue with the party and completing the World Quest.
Don't forget to claim Reputation EXP rewards from the Reputation Board west of the Court of Fontaine. I recommend speed farming EXP until Reputation Level three to get a Gadget called the Crystalfly Trap, which will allow you to farm Crystalflies with zero effort.
