The main goal of the Echoing Tales event is collecting Echoing Conches.
The first event to go live is Echoing Tales, which tasks you with finding Echoing Conches around the Golden Apple archipelago, and runs from launch on June 9th until July 21st.
Currently there are five Echoing Conches available, with more expected to be added over the next few days as the event progresses.
Then once you reach the second part of the event, another 23 Echoing Conches appear throughout the area.
