How to Complete The Final Retreat Quest in Where Winds Meet

In Where Winds Meet, embark on The Final Retreat quest! Speak with Granny Pan at Squarewall Hold to hunt for three gong fragments: one on a roof, another in a ruined house, and the last in a watchtower. Once you gather them all, return to Granny Pan, ring the gong, and enjoy your rewards: 40 Echo Jades, 10 Hexi Exploration, and some coins!
