Without the assistance of their god-queen, the Amuni had begun building their new settlement, which soon resembled their perished ancient culture. The building ground they chose, however, proves unstable and so their settlement suddenly and unexpectedly sinks into the earth. Only a young scout manages to escape in time. He makes it to the nearest town and asks for support there. Players can now help this scout with his problem and gradually excavate the settlement, buildings and ancient stone tablets depicting a powerful cat queen who once ruled a land that fell victim to the desert.

During the event, players can complete quests and scour the outskirts of their town to find provisions that can be traded for shovels, wind in bottles and vacuum flasks. All of these digging tools can be used to unearth the sunken city: Shovels remove the sand from a single field, the wind in bottles blows the sand away in an entire column, and the vacuum bottle clears all adjacent fields of sand. In the process, players can not only earn new daily rewards, but also Amuni knowledge, which can be used to acquire artifacts to upgrade the event`s main building, the "Echoes of the Lost," to the highest level.

In this event, there is once again an exciting league system and the opportunity to acquire the "Royal Prize Pass."

The Sunken City event runs until March 16, 2022.
